Test a webhook endpoint

Sends a signed ping event now and reports what the URL answered. A 2xx within 10 seconds enables an endpoint that was disabled for failing deliveries.

Authentication

Send Authorization: Bearer gtk_…. Create the key under API Access → API Keys. A missing, invalid or revoked key is 401, including while this API is closed. A valid key while the API is closed for your organization answers 404, the same body as an unknown path. Every response includes FounderMCP-Api-Version and FounderMCP-Request-Id.

Path parameters

• webhook_endpoint_id string · required — The endpoint to ping.

Response

• object string · required — Always webhook_test.
• delivered boolean · required — The URL answered 2xx within 10 seconds.
• status_code integer | null · required — The HTTP status, or null when there was none.
• error string | null · required — Why the delivery failed.
• duration_ms integer · required — How long the attempt took.
• webhook_endpoint object · required — The endpoint after the test.
