docusign hmac validation failed connect webhook signature error

Fixes DocuSign Connect webhook deliveries failing HMAC validation in your listener. Use when envelope event webhooks arrive but your signature check rejects them. Not for webhooks that never arrive at all, which is a Connect configuration or delivery problem.

In DocuSign Connect settings, open the active configuration sending to your listener and confirm HMAC signing is enabled on that configuration.

Copy the HMAC key from that configuration into your application secret store again, replacing the old value.

Change the listener to compute the signature over the raw request body exactly as received, before any JSON parsing.

Read the signature header value sent with the delivery and compare its format with what your code expects.

Send a test envelope, capture one real delivery, and verify that single payload locally with the stored key.

Check whether multiple Connect configurations point at the same listener with different keys.
