Payment App No backend requests received from Shopify at checkout

[Asad_A]

Hi @Shawn_Chang ! I have complete the payment app process on checkout page but I don't receive any request from Shopify. After I hit "Complete order", I see the screen saying "Your order's being processed. If you're not automatically redirected, refresh this page", and after it refreshes itself it ends up on the checkout screen with the following message "Your payment can’t be processed for technical reasons. Try again or use a different payment method" (please see the attachments).

Please guide me, how to send request to payment app or send itself. I m stuck here..

Same problem for me, did you find a solution?

Same issue here. There's no any type of request from Shopify when the user clicks "complete order" reach to our server. I believe I set all the requirements correctly by following the documentation.

Any solutions?

Same thing on my side. Have you activated the draft mode on the payment extension? the docs state that if you turn it on, the backend request will go to the url you configured there rather than to your active(and aproved) app extension.

Also have you configured MTLS with the Shopify certificates?  I am currently using nrgork for development and their tools allow to easily configure MTLS
