How to use Stripe Payments in Your Next iPhone app
Traditionally, processing a customer’s payment through your iPhone app would require you bouncing a lot of information between several 3rd party accounts. These complications can be a thing of the past if you instead use the Stripe Suite of APIs to process your mobile payments in your iPhone app instead. By including Stripe in your iPhone app development pipeline, you will surely be using the most up to date billing technology to make the checkout processes in your final product.
Stripe takes care of every aspect of mobile payments so that you can build your own specialized payment forms that look beautiful and integrate seamlessly into whatever environment that you build them into.
The first thing that you will need to begin using Stripe in your iPhone app is going to be a Stripe Account. Making an account with Stripe is fairly easy and accessible through the signup page on Stripe’s website. From there, you will look in your Stripe Dashboard in the account settings tab to find your API key that is needed for the development of your app.
In a mobile app developed in Swift, integrating Stripe’s library into your project requires a bridging header so that you can utilize Stripe’s Objective-C library in your Swift written project. This is simply done by importing Stripe.h and AFNetworking.H into your bridging header. With this done, you are all prepared to begin implementing Stripe payments into your Swift project.
Now you will need to build a way to collect the payment information of your customers. You, as the developer, have some liberty on which route you’d like to go whether it would be through using building your own unique payment form, using Stripe’s own PaymentKit, or even integrating Apple Pay. Just keep note that you will need to have your text fields correspond to the correct outlets in ViewController.swift.
Since Stripe is a secure payment method that utilizes tokens for your customers, you do have to do some backend work in order for the app to function correctly. Though this may seem daunting to some users, you can very easily set up a server using PHP and XAMPP. The only thing that you will have to do to configure the backend of your Stripe payments is to import your Stripe API key into the payment.php file within XAMPP.
Next, to easily send the payment token to the backend so the payment can be processed into your Stripe account, you need to make an HTTP POST request. In this request, you need to submit 4 things to Stripe in order to actually execute the charge. You need to submit the parameters of the currency, amount, and some description (which is ultimately defined by your choices.).
Using Stripe in your next iPhone application can be one of the best things you can do to easily integrate a unique payment method into your commercial apps. Using these tools, making an effective app that not only has high functionality but also provokes trust from the user.
