To create our backend, we will use PHP as the primary language and make use of the library provided by Stripe. So before moving onto the implementation of the app, let’s stop for a minute and setup our server in order to process the payment. Your app will then pass this token to your backend to follow up with the actual charging. For security reasons, Stripe doesn’t charge the credit card which is sent directly from an app. All the text fields are associated with the corresponding outlets in the ViewController.swift file.Īs mentioned at the very beginning of the tutorial, the charging of the customer’s credit card actually happens on our own server. If you’re using the project template, I have already built the payment interface for collecting customers’ payment details. The other thing you may want to obtain is email address, so you can keep a record of the person who makes the donation for later communication. But I also recommend to secure CVC in order to prevent fraudulent transactions and gain a trust from users. Stripe requires us to collect at least the card number and expiration date. In this tutorial, we’ll opt for the third option and build our own payment form. by using Stripe’s built-in payment form component, PaymentKit.through Apple Pay to access your users’ stored payment information.Stripe suggests three ways to collect the payment information: To perform a transaction, your app should have a mean to collect the user’s information. Note: Later when you roll out your app to production, you can update the publishable key to a live one. Note that you have to change it to yours. Here we configure Stripe with our test publishable API key. Lastly, the server side sends a response back to the app about the transaction result.No matter the transaction succeeds or not, Stripe will return you the result. Your web application sends the token to Stripe to perform the actual charging.Stripe has provided us with server code to implement the charging process easily. For security reasons, Stripe requires you to perform the actual charging process through a server instead of the mobile device itself. The next step is to send it to your own server to complete the charging process. Later, you’ll use the token to perform the actual transaction. At this point, the credit card is not charged yet. If the payment information is valid, Stripe will return you a token.It then sends the credit card data to Stripe backend by calling its API. The app first collects payment information including email, credit card number, expiration date, CVC, and payment amount from the payment form.In brief, here is how the app works when the customer sends a payment: Donate App Cycle and How Stripe Worksīefore we dive into the implementation, let’s first see how the app will communicate with Stripe and process the transaction. According to App Store Review Guidelines, if your app supports donation, it should be free and the collection of charitable donations must be done via a web site in Safari or an SMS. In this tutorial, we will create a Demo app called “Donate” to demonstrate how to accept credit card payment using Stripe.Įditor’s note: The app is for demo purpose. First, download the project and have a trial run. To save you time from building the app from scratch and focus on learning Stripe, I have created the project template for you. This is one of the reasons why this company expands so quickly and has made its name in the startup world. The integration process is just so straightforward. As you will soon see, on top of the easy-to-use APIs, it even streamlines the registration process. Stripe wants to make online/mobile transactions as easy as possible. With Stripe, you can easily enable your app to take a payment from credit cards and even make recurring payments. You do not have to worry about opening a merchant account or setting up a credit card gateway. It provides friendly APIs that instantly enables businesses to accept and manage mobile payments. So, in this tutorial, I will give you a brief introduction of Stripe, explain how it works and show you how to build a demo app using Stripe’s API for accepting credit card payments. For physical goods like clothing, you’re allowed to use other payment solutions such as Stripe. According to Apple, you’re required to use In-App Purchase to sell digital content such as extra game levels for your game, and bonus content for your apps. I get asked a lot about why iOS developers need to use Stripe rather than In-App Purchase. If you are planning to sell products in your iOS apps and searching for a payment solution, Stripe should be on the top of your list. Stripe provides one of the most powerful libraries for accepting payments online and mobile apps. In this tutorial we will talk about Stripe integration.
