Topics covering webhook creation & management, event handling, Pub/Sub, and Eventbridge, in Shopify apps.
Hello,
Recently I have experienced an issue with HMAC verification from the webhook app/uninstall.
When I check HMAC with GET methods or POST method for mandatory webhook (GDPR) everything is Okay.
The webhook uninstall used to work properly buy now I can't verify the HMAC. I checked with several parameters and the verification still fail.
How can I fix this ?
