Apple Pay on iOS

Accept Apple Pay in your iOS application using Finix.

This guide details how to get started accepting Apple Pay in an iOS application using the Finix API.

Make sure your app follows Apple Pay's Acceptable Use Policy before getting started.

Before you can integrate into Finix:

  1. Create an Apple Developer Sandbox Account
  2. Ensure you are logged into this developer account through iCloud on your Macintosh.
  3. You must use Apple Pay test card numbers from their documentation. Please see Apple developer website .

This guide is only for supporting Apple Pay in iOS applications.

Step 1: Register on the Finix Dashboard

Before you can begin accepting Apple Pay, you need to first verify and register your application with Apple. You can complete this step with the Finix Dashboard.

To register on the Finix Dashboard:

  1. Login to your Finix Dashboard and click Developer.
  2. Click the tab Alt Payment Methods .
  3. Click Add iOS Application and follow the on-screen instructions.

If you are a Core customer, instead of Step 1 please go to the Application you want to accept Apple Pay.

For detailed steps on how to download the certificate file, see the Apple Pay article on creating a payment processing certificate.

Step 2: Create a Payment with Apple

Once registered, your app is authorized to accept Apple Pay payments. At this point, you can also choose to include an Apple Pay button in your iOS app's checkout experience.

When a buyer requests to make an Apple Pay payment, your iOS app must create a payment with Apple by calling the startPayment method of Apple's PaymentHandler. You can find details on how to do so in Apple's PassKit documentation.

When a buyer authorizes a payment, Apple's completion handler reports the success or failure of the payment. Successful payments return a payment token that you need to include in your request to Finix to create a Payment Instrument. Details on how to create a payment with Apple can be found in Apple's PassKit documentation.

Step 3: Create a Payment Instrument with Finix

After creating a payment with Apple, use the payment token that's returned to create a Payment Instrument with Finix.

Your app needs to send the payment token (returned from Apple's completion handler) to Finix as a third_party_token and include a value for name when creating the Payment Instrument.
