Not able to complete order Shopify HPSDK

Not able to complete order Shopify HPSDK

6 0 1

I have created my own Shopify payment gateway, I am trying to mark order as completed on my test store using HPSDK method but getting following error.


I am also trying to make asynchronous callback which is also giving me an error "Notification acknowledgment failed".

Can anyone give me idea what I am doing wrong here?

Hey @Akshay3,

Have you confirmed the signature you're gateway is calculating is correct?

Can you also rule out this similar-sounding issue? 

If necessary after checking the above items, send over an x-request-id response header from one of your unsuccessful callback requests and we can look at the logs further.
