Applies to: In-App Payments SDK - Android | In-App Payments SDK - iOS

Learn how to troubleshoot problems with the In-App Payments SDK.

Cause:

There's a problem with your Apple Pay payment processing certificate or Xcode has cached an older (invalid) certificate.

Solution:

1. Ensure that your Apple Pay certificate in the Apple Developer Portal is active.
2. Verify that you've uploaded the certificate to the Developer Console.

If you continue receiving the error, you might need to clear a cached certificate:

1. Create a new Square CSR for Apple Pay using the Square Developer Console.
2. Sign in to the Apple Developer Portal and create a merchant ID.
3. In the Apple Developer Portal, create a new Apple Pay payment processing certificate for your new merchant ID by uploading the new Square CSR.
4. Upload the new Apple Pay certificate to the Developer Console.
5. Update your Apple Pay merchant ID on the Capabilities tab in Xcode.
6. Update the code that creates your PKPaymentRequest to use the new merchant ID.
