Version 2 of the PayPal API was released earlier this year and it makes it extremely easy to start accepting payments from your progressive web app.
It's so easy, in fact, that I can show you how to integrate it into Angular, React, and Vue in a single video.
Dollar, dollar bills, y'all.
In today's video, you'll learn the basics of the PayPal version 2 API, and how to start start accepting and capturing real payments from your front end JavaScript app, and it's a lot easier than you might think.
If you're new here, like and subscribe, and you can find the full source code on FireShip IO.
Now just Say a few days ago, I implemented PayPal payments on Fireship, and also added the ability to purchase individual courses.
So ironically, you can now use PayPal to pay for my Stripe payments course if you want.
Now, during this integration, I learned that PayPal 2.0 delivers a really nice developer experience.
They've completely revamped the documentation and the API in a way that resembles Stripe payments.
Now in my case, I already have Stripe implemented, so I'm using PayPal alongside it as an additional option, but you can actually use PayPal as a stand alone payment solution to accept credit cards, Venmo, crypto, and more.
What we'll be looking at today is PayPal checkout, which allows you to mount this payment button directly in your application, and it will take care of collecting payment details from the user and can also capture and charge the payment entirely from the front end.
The first thing you'll need to get started is a PayPal Business account.
From there, you can go to the PayPal developers dashboard, and the first thing we'll want to do is create an application.
When you create this application, it will give you 2 sets of API keys.
The sandbox keys are used to make mock payments and to test your integration, and the live keys are used for actual payments in your production app.
Now each of these environments contains 2 API keys, the client ID and the secret.
The client ID is perfectly safe to expose in your front end application, and we'll use that client ID in the Angular, React, and Vue apps.
The secret on the other hand should never be exposed in your front end code or a public GitHub repo.
The secret is used to identify your app to a back end server like Node or Firebase Cloud Functions, so you can use it to interact with the API from the back end, but we actually don't even need to use it in this demo.
And that's because you can use PayPal checkout to do everything entirely from the front end and we'll talk a little bit more about trade offs later in the video.
Now we're going to implement the same basic payment spec in Angular, React, and Vue.
And even though each app is solving the same exact problem the implementation details vary widely.
Let's go ahead and get started with my personal favorite and generate a new Angular app with the CLI.
The first thing we'll do is go into the index HTML file and include the script tag for PayPal JS.
When you include the script tag, you'll also need to pass in your client ID, and and you wanna stick to the sandbox client ID for now.
And, again, you can retrieve that from the PayPal developer dashboard.
Now a quick side note, you might be wondering why using a script tag and not installing an npm module.
The reason payment systems generally use script tags is because they want your site to always have the latest version of the SDK.
A security flaw on a payment system is a very big deal, so they want to make sure that you're not running outdated code.
The next thing I'll do is generate a component, Then in the top of that component, I'll declare a variable for PayPal.
That PayPal script creates a global variable called PayPal that lives on the window object, and that's how we make it known to TypeScript.
The first thing that PayPal needs to do is mount the actual button to the DOM.
So we need to grab an HTML element that PayPal can attach itself to.
In Angular, we can do that with the ViewChild decorator and then pass in the name of the template reference variable, and we can make that reference in the HTML with a hashtag.
Now in these examples, we're just going to hard code the product data directly into the components, but in real life you'll most likely be pulling this information from an API or a database somewhere.
In this example here, we just need some data for the product and then we'll set a boolean that will tell us whether or not that product's been paid for.
When the component is initial utilize is when we'll mount the PayPal button to the DOM element.
So we call PayPal buttons and then pass in the native DOM element to the render method.
We can pass an object to buttons that contains the callbacks used to handle different events that happen in the payment life cycle.
The first thing that happens in the life cycle is the user clicks on the PayPal button, and we need to configure the order details to send to PayPal so they can process the payment.
So we call actions order create, and we can pass in a bunch of custom options here, but at the bare minimum, you'll want to have at least one purchase unit, and that should at least contain a description and an amount with a currency code.
This will send the user over to PayPal where they can authorize the order.
They can check out as a guest with their credit card details, or they can use their PayPal balance or some other form of payment on their account.
At this point, the order is authorized and approved, but the actual funds have not been captured yet, or in other words, the credit card has not been charged.
For most simple use cases.
You can simply capture the payment directly in your front end code by calling actions order capture.
Now it's important to point out that you don't actually need to capture the funds here if you don't want to.
An alternative would be to send the data from this callback to your back end server and then process the charge there.
And that tends to be a better option for more advanced use cases where you might need to validate the payment and then do additional back end work after the payment has been captured.
We're just going to stick with the easy route here and capture the payment directly in Angular, and then we'll set the paid for property to true.
And that's something that you would obviously want to persist in a back end as well in a real application.
And the last thing I'll point out is that there are additional callbacks we can use here as well.
For example, if we want to cache errors, we can use on error to do that.
That takes care of our TypeScript code.
Now we can go over to the HTML and set up our template logic.
We'll use n g f to see if the item has not been paid for, and if not, we'll go ahead and show the price and product details as well as the PayPal button.
And if it has been paid for, then we'll just go ahead and show an order confirmation.
And just like that, we now have a full stack payment solution in Angular.
Now one thing I really like about PayPal is that you can set up multiple mock accounts, and then you could add funds to those mock accounts as well as credit cards and bank accounts and things like that.
So it makes it really easy to test your implementation details in the sandbox, and that also makes it easy to perform negative testing where you handle different error conditions.
In our demo here, you can see we have a successful mock payment, and then it console logs the payment details to the browser.
And you can send this data to your back end to record in a database or send the user formation email and stuff like that.
That takes care of our Angular integration, now let's move on to React.
I'll use Create React App to generate a new application, and we'll want to build this app the modern way, so we'll go ahead and import some hooks like use state, use ref, and use effect.
Now including a script tag in React isn't quite as easy as it is in Angular, and we need to manually create the script and then append it to the Dom.
So we have 2 different pieces of state.
The first one paid for will tell us whether or not the product has been paid and then we'll have a loaded state that will tell us when the actual PayPal script has been loaded.
And if you know of a better way to do this with React Hooks, let me know in the comments.
Then we'll also use the useRef hook so we can set up a reference to a DOM element that the actual PayPal button can be mounted to.
Now at this point, I'm going to jump into the JSX and build out the template.
This follows the same general structure that we saw in Angular.
If the item has been paid for, then we'll show the confirmation.
Otherwise, we'll go ahead and show the actual product details and the payment button.
And to grab an empty div from the dom for the button, we'll go ahead and use that reference that we defined with the use ref hook.
Now the next thing we need to do is get the actual PayPal JS script into our code.
We can do that imperatively in the useEffect hook and then we'll define the script source as the same source that we used in the Angular app.
But this time we want to add an event listener to the load event and then when it's finished loading will set the loaded property to true on this React component.
Once we know that the script's been loaded, we can then initialize our PayPal button.
But for whatever reason, I had to wrap this in a set time out because there seems to be some weird issue between one of the dependencies in PayPal JS and React, but feel free to submit a pull request if you have a good workaround for this demo.
Now at this point, we can access PayPal from the window object, and then we'll have the exact same code that we wrote previously in the Angular example.
The only difference is that we're using React Hooks to update estate and to grab the DOM element to mount the actual button itself, and that's all it takes to get started with React.
And if you check out the PayPal JS repo, you'll see an example for React in there as well, but it doesn't use hooks.
But enough of React, let's go ahead and move on to Vue.
We can start by generating a new Vue app with the Vue CLI, and then we'll start by defining the template because it's conveniently located at the top of the file.
The template logic is very similar to Angular because Vue also uses directives.
So again, we'll show the item details if the item is not paid for, and then if it is paid for, we'll show the order information.
And then we'll also make a reference to an empty div with a ref of PayPal.
The next thing we'll do is define the data for this component which is exactly the same as React, but instead of hooks, we use a data function that returns an object with the data that we use in this component, and Vue will react automatically if we change any of the properties on this object.
The next thing we'll do is append the PayPal script to this application in the mounted life cycle hook.
This is the exact same thing we did in the use effect hook with React.
When the script is loaded, we'll have access to the global PayPal object, and then we'll mount it to that empty div that we made a reference to earlier.
From there the callbacks will be the same as the previous examples where we first create the order and then we capture the order and handle any errors if necessary.
And and that's all it takes to implement PayPal in a Vue app.
Well, that was easy.
Yeah, I guess it was.
My goal with these three examples was to show you how easy it is to start monetizing your progressive web app, but if you want to learn more advanced techniques, consider becoming a pro member to enroll in the Stripe Payments Master Course.
You'll learn how to build and test a reliable payment system that can work with any front end framework.
Thanks for watching, and I will talk to you soon.

We can start by generating a new Vue app with the Vue CLI, and then we'll start by defining the template because it's conveniently located at the top of the file. The template logic is very similar to Angular because Vue also uses directives. So again, we'll show the item details if the item is not paid for, and then if it is paid for, we'll show the order information. And then we'll also make a reference to an empty div with a ref of PayPal. The next thing we'll do is define the data for this component which is exactly the same as React, but instead of hooks, we use a data function that returns an object with the data that we use in this component, and Vue will react automatically if we change any of the properties on this object. The next thing we'll do is append the PayPal script to this application in the mounted life cycle hook. This is the exact same thing we did in the use effect hook with React. When the script is loaded, we'll have access to the global PayPal object, and then we'll mount it to that empty div that we made a reference to earlier. From there the callbacks will be the same as the previous examples where we first create the order and then we capture the order and handle any errors if necessary. And and that's all it takes to implement PayPal in a Vue app. Well, that was easy. Yeah, I guess it was. My goal with these three examples was to show you how easy it is to start monetizing your progressive web app, but if you want to learn more advanced techniques, consider becoming a pro member to enroll in the Stripe Payments Master Course.
You'll learn how to build and test a reliable payment system that can work with any front end framework. Thanks for watching, and I will talk to you soon.

Version 2 of the PayPal API was released earlier this year and it makes it extremely easy to start accepting payments from your progressive web app. It's so easy, in fact, that I can show you how to integrate it into Angular, React, and Vue in a single video. Dollar, dollar bills, y'all. In today's video, you'll learn the basics of the PayPal version 2 API, and how to start start accepting and capturing real payments from your front end JavaScript app, and it's a lot easier than you might think. If you're new here, like and subscribe, and you can find the full source code on FireShip IO. Now just Say a few days ago, I implemented PayPal payments on Fireship, and also added the ability to purchase individual courses. So ironically, you can now use PayPal to pay for my Stripe payments course if you want. Now, during this integration, I learned that PayPal 2.0 delivers a really nice developer experience. They've completely revamped the documentation and the API in a way that resembles Stripe payments. Now in my case, I already have Stripe implemented, so I'm using PayPal alongside it as an additional option, but you can actually use PayPal as a stand alone payment solution to accept credit cards, Venmo, crypto, and more. What we'll be looking at today is PayPal checkout, which allows you to mount this payment button directly in your application, and it will take care of collecting payment details from the user and can also capture and charge the payment entirely from the front end. The first thing you'll need to get started is a PayPal Business account. From there, you can go to the PayPal developers dashboard, and the first thing we'll want to do is create an application. When you create this application, it will give you 2 sets of API keys. The sandbox keys are used to make mock payments and to test your integration, and the live keys are used for actual payments in your production app. Now each of these environments contains 2 API keys, the client ID and the secret. The client ID is perfectly safe to expose in your front end application, and we'll use that client ID in the Angular, React, and Vue apps. The secret on the other hand should never be exposed in your front end code or a public GitHub repo. The secret is used to identify your app to a back end server like Node or Firebase Cloud Functions, so you can use it to interact with the API from the back end, but we actually don't even need to use it in this demo. And that's because you can use PayPal checkout to do everything entirely from the front end and we'll talk a little bit more about trade offs later in the video. Now we're going to implement the same basic payment spec in Angular, React, and Vue. And even though each app is solving the same exact problem the implementation details vary widely. Let's go ahead and get started with my personal favorite and generate a new Angular app with the CLI. The first thing we'll do is go into the index HTML file and include the script tag for PayPal JS. When you include the script tag, you'll also need to pass in your client ID, and and you wanna stick to the sandbox client ID for now. And, again, you can retrieve that from the PayPal developer dashboard. Now a quick side note, you might be wondering why using a script tag and not installing an npm module. The reason payment systems generally use script tags is because they want your site to always have the latest version of the SDK. A security flaw on a payment system is a very big deal, so they want to make sure that you're not running outdated code. The next thing I'll do is generate a component, Then in the top of that component, I'll declare a variable for PayPal. That PayPal script creates a global variable called PayPal that lives on the window object, and that's how we make it known to TypeScript. The first thing that PayPal needs to do is mount the actual button to the DOM. So we need to grab an HTML element that PayPal can attach itself to. In Angular, we can do that with the ViewChild decorator and then pass in the name of the template reference variable, and we can make that reference in the HTML with a hashtag. Now in these examples, we're just going to hard code the product data directly into the components, but in real life you'll most likely be pulling this information from an API or a database somewhere. In this example here, we just need some data for the product and then we'll set a boolean that will tell us whether or not that product's been paid for. When the component is initial utilize is when we'll mount the PayPal button to the DOM element. So we call PayPal buttons and then pass in the native DOM element to the render method. We can pass an object to buttons that contains the callbacks used to handle different events that happen in the payment life cycle. The first thing that happens in the life cycle is the user clicks on the PayPal button, and we need to configure the order details to send to PayPal so they can process the payment. So we call actions order create, and we can pass in a bunch of custom options here, but at the bare minimum, you'll want to have at least one purchase unit, and that should at least contain a description and an amount with a currency code. This will send the user over to PayPal where they can authorize the order. They can check out as a guest with their credit card details, or they can use their PayPal balance or some other form of payment on their account. At this point, the order is authorized and approved, but the actual funds have not been captured yet, or in other words, the credit card has not been charged. For most simple use cases. You can simply capture the payment directly in your front end code by calling actions order capture. Now it's important to point out that you don't actually need to capture the funds here if you don't want to. An alternative would be to send the data from this callback to your back end server and then process the charge there. And that tends to be a better option for more advanced use cases where you might need to validate the payment and then do additional back end work after the payment has been captured. We're just going to stick with the easy route here and capture the payment directly in Angular, and then we'll set the paid for property to true. And that's something that you would obviously want to persist in a back end as well in a real application. And the last thing I'll point out is that there are additional callbacks we can use here as well. For example, if we want to cache errors, we can use on error to do that. That takes care of our TypeScript code. Now we can go over to the HTML and set up our template logic. We'll use n g f to see if the item has not been paid for, and if not, we'll go ahead and show the price and product details as well as the PayPal button. And if it has been paid for, then we'll just go ahead and show an order confirmation. And just like that, we now have a full stack payment solution in Angular. Now one thing I really like about PayPal is that you can set up multiple mock accounts, and then you could add funds to those mock accounts as well as credit cards and bank accounts and things like that. So it makes it really easy to test your implementation details in the sandbox, and that also makes it easy to perform negative testing where you handle different error conditions. In our demo here, you can see we have a successful mock payment, and then it console logs the payment details to the browser. And you can send this data to your back end to record in a database or send the user formation email and stuff like that. That takes care of our Angular integration, now let's move on to React. I'll use Create React App to generate a new application, and we'll want to build this app the modern way, so we'll go ahead and import some hooks like use state, use ref, and use effect. Now including a script tag in React isn't quite as easy as it is in Angular, and we need to manually create the script and then append it to the Dom. So we have 2 different pieces of state. The first one paid for will tell us whether or not the product has been paid and then we'll have a loaded state that will tell us when the actual PayPal script has been loaded. And if you know of a better way to do this with React Hooks, let me know in the comments. Then we'll also use the useRef hook so we can set up a reference to a DOM element that the actual PayPal button can be mounted to. Now at this point, I'm going to jump into the JSX and build out the template. This follows the same general structure that we saw in Angular. If the item has been paid for, then we'll show the confirmation. Otherwise, we'll go ahead and show the actual product details and the payment button. And to grab an empty div from the dom for the button, we'll go ahead and use that reference that we defined with the use ref hook. Now the next thing we need to do is get the actual PayPal JS script into our code. We can do that imperatively in the useEffect hook and then we'll define the script source as the same source that we used in the Angular app. But this time we want to add an event listener to the load event and then when it's finished loading will set the loaded property to true on this React component. Once we know that the script's been loaded, we can then initialize our PayPal button. But for whatever reason, I had to wrap this in a set time out because there seems to be some weird issue between one of the dependencies in PayPal JS and React, but feel free to submit a pull request if you have a good workaround for this demo. Now at this point, we can access PayPal from the window object, and then we'll have the exact same code that we wrote previously in the Angular example. The only difference is that we're using React Hooks to update estate and to grab the DOM element to mount the actual button itself, and that's all it takes to get started with React. And if you check out the PayPal JS repo, you'll see an example for React in there as well, but it doesn't use hooks. But enough of React, let's go ahead and move on to Vue. We can start by generating a new Vue app with the Vue CLI, and then we'll start by defining the template because it's conveniently located at the top of the file. The template logic is very similar to Angular because Vue also uses directives. So again, we'll show the item details if the item is not paid for, and then if it is paid for, we'll show the order information. And then we'll also make a reference to an empty div with a ref of PayPal. The next thing we'll do is define the data for this component which is exactly the same as React, but instead of hooks, we use a data function that returns an object with the data that we use in this component, and Vue will react automatically if we change any of the properties on this object. The next thing we'll do is append the PayPal script to this application in the mounted life cycle hook. This is the exact same thing we did in the use effect hook with React. When the script is loaded, we'll have access to the global PayPal object, and then we'll mount it to that empty div that we made a reference to earlier. From there the callbacks will be the same as the previous examples where we first create the order and then we capture the order and handle any errors if necessary.

The
the
only

is
is
that
that
we're
we're

you'll
you'll
see
see
an
an

there
as

it
it

But
but
enough
enough
of
of
React,

let's
let's
go
go
ahead
ahead
and
and
move
move
on
on
to
to
Vue.

We
we
can
can
start
start

The PayPal API release allows for easy payments through the front end of an app and integrates with various platforms. Payment information is easily processed through a script tag and a component in the front end. The speaker provides instructions on how to access and process payment information and explains the use of a script tag and a component in the front end. They also provide instructions on how to use the app in React and explain how to access a reference for a referral. The speaker concludes by reminding the audience to consider becoming a pro member to enroll in the Stripe Payments Master Course.
