Functions
Verifies the Shopify HMAC signature.
Every request or redirect from Shopify includes an HMAC signature that can be used to ensure that it came from Shopify.
This function will compute an SHA256 HMAC digest based on the provided
message
and shared_secret
. The digest is then compared to the hmac
signature. If they match, verification has passed. Otherwise verification
has failed.
