Send a test event to a webhook endpoint
The webhook_endpoints.test operation: POST /api/v1/webhook_endpoints/{id}/test in the REST API and the webhook_endpoints_test tool in the MCP server.
/api/v1/webhook_endpoints/{id}/testSends a webhook_endpoint.test event to this endpoint only, signed like every delivery, so you can check that
your receiver verifies Ownrecord-Signature and answers 2xx. It works for enabled and disabled endpoints.
The call returns the queued delivery at once; it is attempted right after (one attempt, no retries). Read the
outcome with webhook_deliveries.get: status, responseCode and the start of your response body. The test
event isn't part of the event feed, and endpoints can't subscribe to it.
