Im using envelope level connect keys and setting the includeHMAC to true in the eventNotification object of the envelope.

This works and the x-docusign-signature headers are being sent as part of the call. We are using this with a client and initially the x-docusign-signature headers were coming through. But the x-docusign-signature headers are no longer present. Ive checked with our client and the connect key still exists for that account.

Is there any reason or a configuration setting that would stop the headers coming through?
