Any business that is developing an e-commerce application will certainly consider Stripe when it comes to processing payments. Stripe SDK has increased in popularity tremendously in the last 5 years, and it represents our preferred payment processor in our app templates. Integrating Stripe Firebase in iOS is extremely powerful, but quite challenging, which is the reason why we have written this tutorial.
We are going to cover a series of critical aspects of mobile payments. What are the components of a payment feature? How do they work together? How is Stripe integrated with Firebase? Accepting payments in a mobile native app has been traditionally challenging, so we hope you are as excited about this tutorial as we are.
Stripe is a payment support platform with user-friendly APIs, allowing developers to seamlessly integrate payments processing into their web and mobile apps. You can learn more about Stripe on their website. We would like to describe some important keys, which are random strings that you need to add into your app. It is used to create an ephemeral key, which is used for securing credit card management.
Secret key As the name implies, it is a secret key that you must keep confidential. With this key, you can perform transactions such as payments, delete transaction history, refunds, etc. Wondering about what a customer ID is?
Initially, while creating a new account, we also trigger a function which requests the Stripe server to give us a new Stripe account a. The Stripe server will return a customer ID as a result, which we can use to process all subsequent payments for that user. While that will make it easier to accept payments in iOS apps, handling the actual payment in Firebase keeps our code private and more secure.
Another benefit of processing payments server-side is that we can use the same code for all client platforms, such as Android or Web. In this section, we will list out what you need to do on the Firebase server-side, with cloud functions. Check it out this example provided by the official Stripe documentation. Pay attention to the following block of code. Similarly, we will have other functions such as adding a Payment source addPaymentSource or making payments makePayment.
You can find out more right on that example page. Nothing new at all. How to integrate Stripe in your iOS app using Firebase? So what is the ephemeral key? Then add this Swift method to that class:. As you can see, there are two important parameters in that request. The reason why we need two parameters is that they are required by the Stripe API.
It looks like this. At this point, we will need a view controller whose purpose is to help users fill in the necessary information, then proceed with payments for example, CheckOutViewController. We will need to pay attention to two objects: a. A customer context. You can also set the amount to be paid from here.
The amount is usually the total amount of the order.React Stripe. It allows you to add Elements to any React app. The Stripe. You can use Elements with any Stripe product to collect online payments. To find the right integration path for your business, explore our docs. This doc assumes that you already have a basic working knowledge of React and that you have already set up a React project. If you are new to React, we recommend that you take a look at the Getting Started guide before continuing.
Install React Stripe. Include the Stripe. Always load the Stripe. Do not include the script in a bundle or host a copy of it yourself. The Elements provider allows you to use Element components and access the Stripe object in any nested component. Render an Elements provider at the root of your React app so that it is available everywhere you need it.
The loadStripe function will asynchronously load the Stripe. Pass the returned Promise to Elements. Replace it with your actual publishable API keys to test this code through your Stripe account. A Stripe object or a Promise resolving to a Stripe object. The easiest way to initialize a Stripe object is with the the Stripe.

Once this prop has been set, it can not be changed. You can also pass in null or a Promise resolving to null if you are performing an initial server-side render or when generating a static site. Optional Elements configuration options. See available options. Once the stripe prop has been set, these options cannot be changed. Element components provide a flexible way to securely collect payment information in your React app.
You can mount individual Element components inside of your Elements tree. Note that you can only mount one of each type of Element. There are many different kinds of Elements, useful for collecting different kinds of payment information.

An object containing Element configuration options.After that, I am going to be using the firebase cloud function to talk to stripe API in order to create a charge. I expect you to be familiar with a basic understanding of vuehow components work, how to Create A Project in Firebase and Make Queries to the Cloud Firestore. As you can see on the Checkout. Stripe will attach the input field to each. The final step would be to instantiate the stripe object inside the mounted function using the publishable key.
Assign it to the stripe property that is declared on the data object. The first thing to do is to create an element object by invoking elements method on the stripe object inside createAndMountFormElementslike so. Then, create a stripe element by calling create method on the elements object by passing a name called cardNumber as a first argument and assign it to this.
For more info have a look at the stripe elements page. After that, attach custom element card-number-element to the stripe element this. As you can see, stripe elements are already giving some validation out of the box. Invoke createToken method on the stripe object by passing any one of the three stripe elements as an argument which will give back a promise. Note: Inside createToken function, I can also check server side card errors such as insufficient funds, etc.
Go ahead and create another property called amount to the data object and give it an initial value of 25, then bind it to the template where it says So, I will be adding the currency property on the server end for fun but you could add it in here as well. Note: Stripe request object is not just limited to three properties. Have a look at what other properties you can add to it here. Next, go ahead create a firebase project and obtain configuration code. Note: If you want to know how to create a firebase project in order to get the configuration data, check it out here.

Following the Stripe Documentation it seems like having its own Server is required. So first, which one to use? The good old Industry trusted http endpoint with good old Retrofit? Or the much more simple Write to Firebase Database to trigger the function? Also, as for the next step, I could not find any Android tutorial for the next steps.
Only thing Android is doing is entering card details, sending token, triggering and listening for future charges. As far as HTTP is concerned, concept is similar but only thing different is you wait for the response and if there is any errors you get it there, whereas if you were to do with Cloud Functions, you would have to write those errors somewhere and read those from client.

Stripe Elements is their pre-built library of UI components that help you easily create your own checkout flows.
Check out this post if you're interested in integrating Stipe Elements into an Angular app instead. Stripe Elements is a collection of components with a variety of elements you can use to create checkout forms like buttons and inputs for collecting information from the user.
The card element lets you collect card information all within one element. It includes a dynamically-updating card brand icon as well as inputs for number, expiry, CVC, and postal code. Stripe Elements is available as part of Stripe.
Stripe suggests always including it directly onto your index. Stripe Elements handles and initializes its own UI and so there can be conflicts if Vue. To avoid this, setup Stripe Elements after the Vue. In order to customize the style of the element you have to declare the styles inside of an object:. Stripe allows you to collect and convert card information collected by Elements into a single-use token that you can then pass into your server to use in an API call. You could have a purchase method bound to a button and then call the stripe.
Still though, sometimes different types of errors can get through, and Stripe Elements lets you handle that inside of the createToken method with the result. Make sure you checkout the documentation for more information. What is Stripe Elements? Installation Stripe Elements is available as part of Stripe. Tweet It.Finally, I will teach you how to get all the user accounts at once when the signed-in user has admin privileges and change user roles using Firebase callable function.
Go ahead and create a project on the Firebase Console and include the initialization code inside the main. I use semantic UI but feel free to use your favorite.
Integrating Stripe Elements and Vue.js to Set Up a Custom Payment Form
I have included CDN link in the index. When the user role is set via auth custom claims, it will become available after signing out and signing back in. For that reason, I have signout functionality below after creating a new user account.
If you have any better solution than this, please let me know in the comment section below. I assume that you already know how to get up and running with Firebase Cloud Functions. The AddUserRole function will be triggered when a new Firebase user account is created. Also, store user data to the Cloud Firestore under roles collection. This way, you can get all the user information later when having admin privileges. When you log in with the user you have already created, you will be able to see the admin property is set to true inside the custom claims object.
React Native - Stripe project
For that, go to AddUserRole function on the back-end, replace admin property to customer in the custom claims object. The reason I use the customer role as a default is because I assume most of my users will come under that role. You may wonder what if I want to change roles, such as changing a customer to a driver for a specific user later?
Inside the beforeEach method, I am checking to see if a user is logged in or not using the onAuthStateChanged method. If there is a user, get an idTokeResult that has the claims object in which I can get the user role that was set when creating a new user account. This view has a simple heading, user email and sign out button and the driver view is identical except for the heading text.
Only admin will be able to see all the user data from the roles collection inside created method. Now, add a drop-down menu next to each user with the roles they can switch to and send uid and new role data to the callable function called setUserRole on the backend. First, check to see if the request was made by an admin using custom claims on the server-side.
Then, set a new role to the custom claims object by uid as well as update the corresponding document to reflect the role change. Here is the full source code on Github. Feel free to reach out to me in the comment section below if something is not working as expected and I will get back to you as soon as possible.
