Apple Pay payment processing certificate error “CSR algorithm/size incorrect. Expected: RSA(2048)

Posted on

This error usually pops up if you try to upload Braintree’s CSR file to generate a Merchant Identity Certificate instead of a Payment Processing Certificate in Apple developer portal. Please confirm that you're clicking the Create Certificate button under the Payment Processing Certificate section and not Merchant Identity Certificate section. You can check out our Apple Pay configuration guide for more details.


Important: An Apple payment processing certificate is only required if you’re implementing our Apple Pay solution in your iOS app with Braintree iOS SDK. If you want to accept Apple Pay payments on your website (Apple Pay on the Web), you only need to add your domain in Apple Pay settings in Braintree Control Panel.
