Architectural Option Analysis: Securing Data Flow from Shopify Webhooks to an API Behind Kong Gateway
When integrating Shopify webhooks with an internal API protected by the Kong API Gateway, one of the first—and most critical—challenges you’ll encounter is authentication. Shopify signs its webhook payloads using an HMAC-SHA256 signature, which is delivered in a custom HTTP header (x-shopify-hmac-sha256). Unfortunately, this doesn’t align neatly with standard authentication mechanisms, especially those built into…
