ApplePay iOS error - This device cannot make payments

Question

When integrating ApplePay with my test app, I get the error:

This device cannot make payments

I have setup a card to use, and tested it at a Point of Sale terminal - works fine there.

The line of code that should be working (but doesn't) is:

PKPaymentAuthorizationViewController *auth = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:paymentRequest];

Answer 1

Apple's documentation is woefully inadequate in listing integration steps in detail.

Apple's Getting Started with Apple Pay document mentions these bullet points:

Prerequisites

In addition to implementing Apple Pay with the PassKit framework, you must:

• Set up an account with a payment processor or gateway, if you don’t already have one
• Register a Merchant Identifier via Certificates, Identifiers & Profiles
• Submit a Certificate Signing Request to obtain Public and Private keys that will be used to encrypt and decrypt Payment Tokens
• (missing step) Include the Cert in your KeyChain
• Include an Apple Pay entitlement in your app.

In my case, I'd forgotten step 3. The fix is to submit a new CSR with the merchant ID created in step 2, and include the resulting certificate in your keychain.

Edit: But wait, there's more!

You also need to go to the AppIDs section of your Apple Member Center and edit the App ID for the app to include the merchant account id you just created. Otherwise your app will not be provisioned to use the merchant id. After that, go to Xcode preferences and refresh your provisioning profiles (or download and install them manually if you need to).

These steps should get you past the "This device cannot make payments" error.

Answer 2

Make sure the Credit card you setup on Passbook is verified...otherwise, PKPaymentAuthorizationViewController will return nil.
