HTTP_X_SHOPIFY_HMAC_SHA256 by Kevin Scheurs

Hi there,

I noticed per http://docs.shopify.com/api/tutorials/using-webhooks#verify-webhook that this header is only sent for webhooks created through the API. Is there any way to add a default App or attach a shared secret to the seller account so all webhooks (even ones created through the admin interface) can benefit from this security check?

Thanks!
Kevin
