this episode: https://github.com/cjavilla-stripe/rails-accept-a-payment If you have any questions, feel free to reach out to me on Twitter @cjav_dev :D #rails #rubyonrails ## Transcript all right so i think we're live again um we had some i had i messed up i did not uh i did not go back to um to the browser here so i've been chatting with aaron here about um you know watching sca or so so aaron watched the sca for accepting payments on stripe on youtube where i used sinatra but aaron is using rails and has shared a repository here with me where they are going through and creating these submissions where folks are submitting films and they're collecting payments for these films so i just recorded like 20 minutes and went on and like built some of a rails app but i realized that like i wasn't actually sharing my screen it was all like just me uh talking so instead i am like super optimized now for showing you what's actually going on on the screen instead of just what's uh what's here also before i forget um in this in this last thing i was talking about um how for chris sanchez this was another question that came in we got two questions this week about how to use stripe with rails chris sanchez again sorry i'm gonna do without react this time and we're gonna do one time payments with payment intents and then we'll come back in the next episode and do rails with react um and yeah if you haven't checked out the hundred days of code yet super cool uh for new folks so today what we're gonna do is we're gonna talk about stripe elements and collecting and accepting a one-time payment with stripe elements using ruby on rails and then later we'll do collecting payment with stripe checkout in rails and the big difference is that stripe elements is a set of form controls that you use to build your own html forms and stripe checkout is a stripe hosted page where you can redirect customers to to create collect one-time payments accept these payment details in setup mode or start recurring subscription so checkout is a little bit easier to implement you offload a lot of regulatory requirement addition of payment methods localization tons of stuff to stripe if you use stripe checkout if you use stripe elements you build a lot of those forms yourself so that's we're going to do today is build our own custom form to accept one of these things called a submission and we're going to um yeah so just going to kind of go through how to accept a one-time payment in an sca-friendly way and i'm going to go through this uh best as i can here without without too much hopefully okay so this is uh aaron was kind enough to share his setup here so what's going on is there is a it's a rails application and there's a controller called submissions and the submissions controller is receiving post requests and it's creating a new submission model this is a rails database model and then separately it is setting the user and then calling save and charge and save and charges creating a stripe charge object and the stripe charge object once it's saved everything is good and then you can kind of like send your submission mailer this is what i would call fulfillment and so i'm glad this is the example because there's a couple things that go into this number one payment intents are asynchronous and so we want to deal with or they're not they're not asynchronous but we want to deal with the fulfillment in an asynchronous way by listening to web hooks rather than handling them synchronously just like this because it's possible the user is going to confirm the payment intent but then their browser might disconnect or they might have a network connection error or something before uh before coming back to your site and so or before you're able to handle that with javascript to tell your own application that it's successful so we want to handle these fulfillment options with a web hook handler so the very first thing i'm going to do is create a new rails application and it looks like this i'm going to say we're calling it accept a payment i'm using dash t to say skip tests because i think by default you get mini tests i like rspec so i always do dash t skip turbo links um turbo links mess with javascript it's like a way to like do p jacks where like only part of the page is loading so i always skip that skip listen i've run into weird issues where rails console and rails server won't start if i use listen and then bit databases postgresql it doesn't really matter what you use for the database but um so that's the command to ins that i'm using to install a new app what i'm going to do is create a submission model i'm also going to create a submissions controller but before we do that i'm going to first install some dependencies get my api keys set up etc etc so i hope that you can see this now we'll jump to this view here so if i say let's uh dependencies first install the stripe jam i like annotate i also like pry rails or when we're working in um in development mode okay so then once those are created i'm going to open up initializers config initializers i'm going to make a new file called strika rb and this is where i'm going to add my api key rails.application.credentials dot stripe secret key and and i'll show you in a minute what my what's setting my api keys looks like so if i just go into here and i say editor uh is vi rails credentials colon edit this allows you to open the credentials editor here and i'm going to say stripe secret key is this thing public key is this thing and my web hook secret is this thing okay so this is what uh the api keys look like and so when i say rails.application.credentials it accesses this encrypted credentials file and then if i say dot stripe that's going to grab this object here and now i can key into that with secret key and that's going to pull out my secret key value okay so that's the reason why i want to use an initializer over setting it in the model object is that when you set it in the initializer it's loaded and available everywhere um when when rails boots so instead this is kind of what was going on here in aaron's submission um database model where we're calling save and charge we were setting the api key here instead of doing it here in the model i want to do it in an initializer and also instead of using charges charges are deprecated so today we're using payment intents it's going to work just a little bit differently so what have we got going on here let's make a um rails new plus steps this is going to be our rails new plus our dependencies are installed rails g controller submissions index new um so i'm going to generate a controller with the index view and a new view so that kind of jumps us into some uh gives us a couple extra things i love the all the rails generators and scaffolding and stuff it makes things so quick to work with so we're generating an index and a new view come on i don't know what's hanging come on all right take a sip i just got my new um pear programming shirt today from [Music] tuple the tuple hardware it's pretty sweet um what is going on here why isn't this going hmm i'm drinking peach tea whoa everything is what's going on again what i thought yeah what is going on hmm hmm undefined method square bracket for nil class so maybe i messed something up here credentials dot sh did i not oh i didn't close this all right so once i close that now this should this should work now uh i think spring was like i'm trying to boot up i'm trying to boot up i'm trying to boot up and it wasn't telling us that it was failing um because i had that i had not saved that thing so that credential didn't exist yet whatever it's cool uh all right so now let's let's also uh rails g model submission it's going to have a title a price stripe payment id and a status for now i'm going to just keep it just like this in an errands application here there's quite a bit more to the schema but i i'm going to leave that i think those those are all like you know implementation details or part of the details of that that business so i'm just going to make the submission be a title price stripe id and status you can also think of this as an order or like an intent to buy something intent to purchase something so create submissions is our migration here's the model if i say rake db drop bb create db migrate that should drop the old database that i created while we were doing the first version of this demo it'll create a new database and it'll migrate and create these submissions okay so in our routes file we've got a couple things here i'm just going to say resources submissions and i'm going to say route to submissions index if we go to here rails s so i'm going to start up my server and it looks like it's going okay cool localhost 3000 and cool cool cool so here's our submissions index that's great um all right so permissions index let's say we want to make a link to um submission slash new create a submission okay this doesn't exist yet so let's make a form there okay new submission okay so if we look at um aaron's form i guess uh new.html sub news at the top we've got this film submission 10 bucks and uh this is using simple form 4. i don't know simple form 4 or the helpers for this so i'm just going to write it from scratch with html so the it's a post request by default um we would be sending it to this slash submissions thing um i know that aaron's form when you're using simple form it creates an id called new and underscore and then the thing so i'm going to add that field so we're going to add a field for the title uh wow that's cool um input text the name is going to be submission title and the id doesn't oh it does matter i guess test submission okay so we're getting close to being back to where we were before all right so we've got this form right now it has one input and it has a title and if we click create submission it's going to send a post request a full page refresh back to rails it's going to post this this data here that includes the authenticity token for csrf checking and our submission title but we don't actually want to submit yet because first what we want to do is we want to add another form element here which is where we're going to mount the stripe.js element so i'm going to call it card just like aaron's was called and what i'm going to do is i'm going to make this an inline script tag so on aaron's form we've got an inline script tag at the bottom here where we're initializing a new instance of stripe we're setting up some fonts some styles we're initializing a new instance of stripe elements creating the card element here so we're creating an element of type card and passing in those styles so they match and then um we are mounting the card is it styler styles the style object let's see i thought it was styles oh it's style totally a styles okay that cool before we do that though we need to go to application html erb so this is the kind of like the master layout or the base template or the kind of like the default aspx or whatever kind of this is the page where um all the other templates are going to build off of and so when we're using stripe.js we want to install it on every single page so i'm adding that script tag at the top here you can put it wherever you want it just the only thing that matters is that stripe.ps is loaded before you try to use it so because i'm loading it in the head and this yield is where this template is being rendered on the left side so all of this code is going to be rendered into where this yield block is so because this code that i'm writing over here is in the yield block and the yield block appears after the stripe.js block i can use stripe.js just directly here um so i can install an instance of stripe.es like this rails.application.credentials.stripe public key i think this matches what aaron has and then i'm actually just gonna copy what they've got for styles and fonts um okay and these i think are one space okay cool all right so the next thing we need to do is initialize an instance of elements and we called okay so this div with id card this id equals card is the css selector that we're using when we mount the card element okay so the hashtag octothorp whatever refers to us working with the id and the fact that we're working with the id and it's card means that we want to use this hashtag id that's a css selector to grab onto this card element you cannot have multiple html elements on the page with the same id they have to be unique um and so yeah so we've got one card element and that should be good to go um cool so what's the next thing that we want to do so on um on aaron's page here we're doing this basically kind of like following the same pattern up to now right and by if we refresh the page we should see a stripe.js element here and we do this is the card number and the cvc etc etc so this is um actually the thing i didn't do that's different is style styles um refresh the page look at that okay so we've got um some cool looking style there so this is loading a i think it's a font from google fonts um and we can enter in our card number oh okay so maybe i should change the background uh let's see uh color um let's see if that no uh okay where is the color changing here all right all right so now we can see the card now we can see the card number all right so what's happening here though if we inspect this is that the um the html element that has id card is being populated and filled out by the stripe element and in fact this is actually using an iframe so that for pci compliance reasons right so if we click create submission at this point we're going to send all the data that's in our form invalid form controls not inside of iframes is going to be sent to our server but because we're using iframes for pci compliance we need to handle some of this with javascript and what we want to do is we want to bundle up these card details so the card number cvc expiry postal code etc etc we want to bundle those up send them directly to stripe and then stripe is going to respond to us on the client with um with a payment method object that is tokenized we call it tokenization when you are taking some data sending it on the front end and you get back a token this data should not hit your server if you want to depend on and offload your pci compliance burden to stripe into stripe elements so um all right so the next thing we need to do is actually create the payment method and confirm the payment intent and so when the form is submitted before uh we want to use we want to use javascript on the front end so before it ever makes it to the server we want to intercept that form submission and then do some stuff on the front end before we get back to your server okay if we look at this accept a payment integration builder guide here you'll notice that its recommendation so this is on the official stripe docs if you go to the client.js uh let's take a look client.js uh here then you'll notice that on page load we're making a fetch request to this create payment intent route and this is kind of where aaron's original question was there is no create payment intent where is this coming from this isn't really part of rails uh what is this actually doing it's in in the integration builder it's happening on page load we don't want it to happen necessarily on page load it's not required that it happens on page load if you know the amount that you want to charge if you know exactly how much you want to charge cool go ahead create the payment intent on page load if however the form input so if any input of your form is going to modify the cost so it's going to modify the amount that you're charging then you can also make this request to create the payment intent just in time so right before the form is submitted to your server after they click the button but before it's submitted to your server you can still make this fetch request to go create a payment intent this is hitting your server so this is this is a request to your server so a post request is going to be sent to your server your server is going to make a post request to the stripe api to create a payment intent stripes api is going to respond with json to your server your server is then going to return some data about the payment intent that you created back to the client and your this this promise here will resolve with an instance of a payment intent or at least it'll have the client secret of the payment intent so that's the important part we want to create a payment intent with the amount that we want to charge and then we need to use its client secret so that's what we're going to do next and i think what makes the most sense is actually to create a new controller called payment intents rails g model payment intents no not model controller payment intense and this is going to be a purely api controller so like we are we're only going to receive post requests as json and we're going to respond with json okay so if we go to uh there's probably uh there's probably some rails magic thing that tells it that it's only an api controller and not an application controller not sure i'm not sure it matters like a whole bunch but if we say um let's make a create method which is where we're going to receive post requests and then here we can say like uh resources payment intents so this is us adding the route so instead in the in the demo it says create payment intent that's the route that you hit to create a payment intent you send a post request to that route here by using resources instead of create payment intent like this the route is going to be payment underscore intents like that we send a post requested to this and we should hit this create endpoint so here we want to do is uh create a payment intent with the expected amount return the client secret okay so here we can do is say payment intent is equal to stripe payment intent dot create and at a minimum this requires two things an amount which is the amount in cents and the currency you can also pass a whole bunch of other stuff i think there's like a couple dozen so if we look at the um the api reference for creating a payment intent here you will see switch this to ruby um you'll see a whole bunch of different stuff that we can pass so we need we need to pass amount you see required currency required you can also pass confirm a customer description metadata off session these are all like really common things and then there's a bunch of even less common stuff so for now we're just going to pass the amount the currency and that's it um okay so we've got this endpoint that is that is hitting the stripe api to create a payment intent again we don't need to set our api key here because it was already set in an initializer right but we do need to make sure that we're returning the client secret back to the client so i'm just going to say render json of payment intent you can pass the entire payment intent back or you could pass just if you wanted you could just pass like client secret um but i'm just gonna render the entire payment intent um let's make it just client secret so we are going to render this json back so if we um yes yeah okay i was trying to think about whether or not we want to prevent csrf or skip csrf checking i'm going to leave it on and then actually use csrf on the client so we've got a new controller it's called a payment intense controller the only thing it does is create a payment intent i passed in ten dollars here right like uh because i believe that here if we go to uh submission model submission the charge that was being created before was using ten dollars as the amount in usd as the currency um notice that we are not passing in the source or a statement descriptor or any of this we definitely don't want to pass a source we could pass description and statement descriptor i believe let's see is statement descriptor yeah we could pass a statement descriptor let's actually do the same thing so statement descriptor is what is okay sure i'm sync okay and then description order for it looks like maybe a placeholder so that's cool all right so you'll notice though that we're not passing a source we're not passing any stripe tokens we're not passing anything that's actually going to collect payment right now we're just creating the intent to pay we're not actually creating the payment once we create the payment intent we then need to confirm the payment intent so that's going to be a future step so what happens is back on our client submit new right here we've got our we've got our elements all set up they're all styled and everything we want to say i'm going to grab reference to the form new submission and when it's submitted see do that let's see when the form is submitted we're going to make a post request to create payment intent and then we're going to confirm car or confirm create payment method and confirm payment intent all right so the first step here is we want to send a post request to payment intents because that's the name of our route that's the name of our controller all of that matches we're sending some json and right now the only thing that's going to be in the json is the form authenticity token the reason we want to do this is so that we can prevent csrf so that someone outside of our application can't just start pummeling the create payment endpoint so authenticity token is equal to form authenticity token so this is a this is like a rails thing but most web frameworks are going to have some concept of csrf protection okay so what what's happening here is when the form is submitted we are preventing default which says don't actually submit everything to the server yet handle it with javascript then we're making a post request to create a payment intent and then when this resolves successfully this is going to be a some data that's going to have a client secret this is where the second step happens so this is like kind of like a step one and this we'll call this like step two so we create the payment method and confirm the payment intent and the way this works is we say stripe dot confirm card payment and the first argument here is the client secret of the payment intent and the second argument is an object where we pass in the card element okay so here this card element that we created up um up above on shows line 22 now card element here is an instance of a card element that we created with those styles before right so this card element is a javascript object it's mounted in card and is rendering all of those controls for us to enter our card number cvc expiry whatever this card element we want to pass reference to that as under the payment method card slot when we're confirming card payment what this is going to do is confirm card payment will handle sca for us so this is going to do two things this will first it will take our card element input it will create a payment method and then second it's going to attempt to confirm that card payment so when this promise resolves if secure customer authentication was required the user should have seen a modal where they were walked through sca if secure customer authentication was not required they don't see anything but the payment intent gets confirmed the payment method gets created etcetera etcetera but either way it's going to resolve with a promise or this is returning a promise that will resolve with an object here so say then response and the response will either have if risk.error it'll have an error object with a message or it'll have a payment um it'll have a payment method on that object so what we want to do here is say like if there's a response that error i don't know do something to tell the user that something failed otherwise in this case we have like successfully created the payment and we can redirect or fully submit the form or whatever right so here what i think we want to do is say like e form dot submit but before we do that we might want to embed the payment id so i'll call this step three embed payment id in form so i'm going to grab reference to like an input payment id input and here we go we're going to add a new field here it's going to be another hidden field and its id name is going to be submission stripe payment id and its id is payment and its value is nothing so if we look back at submission we haven't uh annotated so notice that there's just like two lines here you only see the class definition and uh this submission thing so what we want to do is um we want to annotate this so we can see what fields exist on submission so i like using this tool called annotate so you can say bundle exec annotate models and that will annotate our models with comments so that at the top now we can see which fields are in the database and available so i just wanted to confirm that this is actually called stripe payment id sometimes i forget so we go back to um submission form okay so back over here we've got our payment id we've got this here set up we grabbed reference to the payment id input payment id input.value is equal to oh i guess we don't actually have the payment rest id let's go back to our payment intent controller and let's let's return the client secret and also the id um that should give us rest.id the data that we're that we're rendering as json here in the payment intense controller is what's available in data we can actually call this maybe like let's change this to be like a payment to make it a little bit more clear and then down here this becomes payment intent dot id okay so we are creating an instance of a payment intent returning its client secret and its id to the client then we're gonna um can confirm and collect the payment on the client we're gonna submit our form that's gonna create a new submission that has a title and it has a straight payment id um let's let's give it a whirl this is this was like a lot of moving parts so i totally get if it's a little confusing so on the new page i'm going to add some break points here in the browser console so that we can see that a little bit better um okay so what's happening now is when we submit the form i'm going to add a break point here just to make sure we're getting inside of the form handler then i'm going to add a break point here to make sure that we created the payment intent successfully then i'll add a break point here to see what happens afterwards so we've got our test submission i'm going to say zc44 okay put in my test card number click create submission the form submission is stopped with prevent default and now we're about to make a network request to slash payment intents to create our payment intent if we click play we get down in here we created this we've got the id of the payment intent we've also got the client secret this looks right okay that is the client secret that we want and now these details are going to be bundled up and sent to stripe to tokenize and confirm that payment intent so this client secret here is the client secret for the payment intent and is going to confirm it and then if that's successful then we'll enter into this then block um and we at that point we will have taken payment so we will have taken payment we won't even have a submission model yet in the database but we will have taken payment so i'm going to click play we've take okay so we've we got back a response object it has a payment intent if we scroll to the bottom we see status has succeeded so this payment intent is now successful we've we've taken payment we're entered we've entered into this block cool we have this payment id input where we're going to grab reference to the payment to that hidden input and we're going to set its value equal to this payment intent id and now we're submitting the form okay so if we click play unknown action submissions okay i didn't spell that right refresh the page nope go back pretty submission test submission let's uh so i'm going to use an sca test card just so you can see what it looks like we click create submission open the modal where then you can see what um what it would sort of feel like again in practice when you're working with sca in production this this model will be populated by the banks sort of like secure customer authentication uh page which will allow the customer to enter a one-time pin or a password or log into their bank or whatever so um in test mode we see this test 3d secure page we can just click complete authentication we enter into our success block and we submitted again to the wrong endpoint am i not spelling it right submissions routes submissions post subs oh we just haven't defined it yet okay so we're we're getting we're getting close let's see how was the submissions controller defined over here so in the submissions controller create method we're creating a new instance of submission with form params see how those are defined so we are going to expect we're going to require permission and we're going to permit title and stripe um payment id because the only things that are coming in that we care about for our submission um and then what are we doing so then if submission save okay we set the user cool so we say if at submission dot save else and um if submission was saved then we want to like redirect to at submission um else we want to render some errors and redirect them back to actually we probably want to like render new uh okay so let me think through this a little bit here so we've got this new submission it has the stripe payment id um and we we have a couple of actions here that we want to automate on right um so yeah because we won't have the idea of the submission in the by this time the payment was successful for sure um because we're not submitting the form until it's successfully resolved so i think this stuff might be safe to do just directly in line here so you might say something like this right like uh s send your emails right here in practice again i think it's a little bit safer so like what what might happen is if you get to this point like right exactly right here if the browser fails and you don't enter the success callback and you don't submit the form then you may have a successful payment and no submission created um and so in order to add some safety rails around this i might actually just send these as part of the um as part of the web hook handler um yeah so if we go back here and refresh the page we should be okay cool okay use submissions go to html.erb uh add the submission title okay so we've got our test submission and um yeah okay so with with web with the web hooks that are coming in one way that we could we could solve this is wait and only process them after we have a submission with that payment intent id filled in um let me think about this a little bit but in the meantime let's just put out like at submission.js we have like some data to look at so we've got the stripe payment intent id we could retrieve this from stripe um the status is null um okay we've got our creator updated at and we have this object okay so couple of thoughts i'm almost wondering if we want to create the submission in this case if we want to create the submission when we're creating the payment intent um so yeah okay so this is this is definitely one way that you could do it right i'm gonna add a save point here um create payment intent and submission separately okay and then right right right yeah the reason why i'm why i'm hesitating is because uh watch let's take let's take a look so if we um rails g controller web hooks i'm gonna add a web hooks controller um and this web hooks controller is going to receive post requests directly from stripe and you don't want to verify authenticity token because it's a post request coming directly from stripe we want to say something like payload is actually i'm just going to go to webhooks build and um under the check signatures stripe documentation we have some an example here that's again written in sinatra but it should be fine or it'll get us like pretty close so we are reading the payload and then our endpoint secret is stored again in rails credentials so rails.application.credentials scrape webhook secret this will verify the event that's coming in so if the payment intent succeeds what we kind of want to do is we want to look up the submission um uh stripe payment id is payment intent id right because event.data.object will be an instance of a payment intent and the um the submission will have a payment id also but i think that we might receive this post request faster than we have a payment intent set up so what i'm going to do is add a find by bang here so that this fails if we try to find a submission that doesn't have this payment intent id and then the web hook will be retried by stripe so stripe is going to retry web hooks for us automatically submissions controller if we don't respond with the 200 or if we don't respond with the 200 xx http response then stripe is going to um retry so if we receive the post request from stripe with a payment intent succeeded event before we have the submission saved because we get the post request for the web hook faster than we have the submission saved then we will just um fail and return with a uh you know um 400 or something status code because we're using find by bang which should raise if we don't have a submission in the database with this id uh otherwise we should return a status 200 um so yeah if i just say like uh render json message success we don't care about this event type yet i think this is where you want to do your submission mailer stuff and probably deliver later and okay let's put um payment intent succeeded uh actually let's put that above and then let's say um submission found at submission dot in title okay so how do we test this how do we test this you may wonder stripe cli so the stripe the stripe command line oh here it is stripe cli is a tool for helping you build test and manage your stripe integration right from the terminal as the pitch says and so what we're going to do is uh create a listener with stripe listen so you can kind of see that here this stripe listen command super cool that's going to set up a direct connection between stripe and our local account so if i say stripe listen stripe listen dash dash forward two local host 3000 slash web hooks i'm remembering that we may not have set this up in here yeah resources webhooks only uh create but this says create a you know a route for slash web hooks that's going to go to that create action and it only receives post requests we don't want to list anything we don't want to allow access for other any other methods in here we only want create um so okay so now that we're listening any event that happens on our stripe account um in terms of web hooks will be output here so what's uh let's let's go back to the entire let's go back through the entire flow or actually like uh yeah let's do it so go back to uh submission slash new and enter a card number i'm just gonna use 4242 for now um we create a submission and then you'll see over here the payment intent was created it succeeded the charge succeeded all of those are being posted directly to this webhook endpoint if we look at the server log we are seeing post requests come into this web hook um let's see so we received a post to the webhook endpoint for this event and this event type is super hard to see in here let me see if i can find okay so payment intent succeeded so yeah okay so here's our log submission found test submission cool and here is okay so here was the request for here was the post request where we created the submission before that before we created the post request for the submission we did get an event but it was of type payment intent created so this is it's totally possible for this to happen um where it would fail um let's see if we can get it see if we can make it happen here or it fails um oh complete and we should see some more events happen cool um submission found okay so what's what's happening here is it continues to find the submission that's cool we want to say add submission uh update uh status maybe to paid or something and then we want to send these two emails um which i'm going to leave as an exercise for the reader you can say like rails g submission mailer and kind of like set up the submission stuff and yeah so i think this is roughly how i would build this uh yeah here i might say like render json signature verification failed and then status 400 same thing but invalid json um okay and again the reason that we use a web hook endpoint is so that if a submission um if the submission of a submission uh if the submission of a submission um so if if again if the browser disconnects or there's a network disconnection between when the payment is confirmed and when this promise is resolved if there's some sort of disconnect there you want to be able to still fulfill the payment which you can do when you receive those web hooks you could also add some like other handling in the web hook to like look up the submission if it doesn't find one even after you know 10 tries or something then um send you an email as the administrator to know like okay this is this thing is broken so hopefully this was helpful i'm gonna put this code up on github and share it and i'll just i'll put a link in the description um uh okay cool i hope hopefully this was helpful i know i was like super rushing because in the last episode i had full screen i had like the full screen face situation where i was just talking through stuff and i was showing things on screen but i didn't realize that the screen wasn't shared so i kind of uh called an audible restarted hopefully this is okay thank you for watching please let me know if this answered your question if it did not answer your question um i really want to like make sure that we're uh putting out good content that is helpful and um that you're able to successfully build your business based on the stuff that we're putting out so if this wasn't enough or if you still have questions let me know and we can wind it back and and roll it again so um but yeah i think i'm gonna end there and wish you all uh yeah happy uh happy day happy rest year --- [Back to all videos](https://www.cjav.dev/videos) --- ## Hey Agent, thanks for visiting!
