I am integration the ETN instant-payment in nodejs. There are one issue i am facing, i couldn’t match the SIGNATURE hash with mine. Using library ‘js-sha256’, i’m doing sha256.hmac(‘secret_key’, ‘payload’), it wasn’t the same result as the SIGNATURE hash send to me.
However, i tried the webhook in the vendor setting, it works totally fine… Anyone has the same issue? or someone can help me?
