POST/api/v1/webhooks/{id}/rotate

Rotate a webhook signing secret (dual-sign during grace window)

Generates a new HMAC signing secret for the webhook. During the configurable grace window, outbound deliveries are signed with BOTH the new and previous secrets (header X-EvalGuard-Signature-Previous) so receivers can roll their verifier without dropping events. After the grace window expires, only the new secret is used.

Authentication

Send Authorization: Bearer YOUR_API_KEY on every request. Generate API keys at /dashboard/api-keys.
