Chris,
I am trying to use the Shopify Webhooks feature in order to ping a custom URL that we have created, but my Shopify Webhook requests are missing the needed "x-shopify-hmac-sha256" request header in order to authenticate.
http://requestb.in/1a6b5471?inspect
These 2 requests are from using the "send test notification" feature but that header is also missing from live requests.
Do I need to activate something to see that "x-shopify-hmac-sha256" request header? Once I see this, I can use Tim's code (thanks!) to validate the request. Thanks for the help!
Ryan
