Payment gateway app error message

[sanjay7]

We have a live payment app with shopify. Shopify is sending a payment request to app provider server and on it, there is cancel_url like this: "https://my-test-shop.com/1/checkouts/4c94d6f5b93f726a82dadfe45cdde432" but here, we are not abel to send a error message along with the cancel_url

can you please guide us, how can we add a error message to cancel url or how can we send a error message to customer where there is any error happened on payment app or transaction.

Yes, we are also facing this same problem with new payment app upgrade. Can anyone help us to understand how we can inform or send back the error message to customer/end user via the cancel url redirect instead of calling the reject mutation if something went wrong in the payment transactions.

No, we have not got any solution, we are not able to send a error message with failure.
