Hey AC,
just a heads up that your Webhook UI (the one under Settings > Developers > Webhooks) offers a way to define Signature and other Headers. When entered and saved, the signature/headers is shown again while editing the same webhook (so it seems they are correctly saved along the other webhook data).
BUT: neither signature (which itself is also just a header with redacted value field) nor the other public headers are sent along. Not while sending test data, nor when receiving real triggered data.
Please fix this bug asap or remove the UI that suggests the feature is available.
PS: If it helps, the webhook in question is an unsubscribe webhook with contact, user and system initiated sources.
