It is not logged and does not change the failure count. When the endpoint is not allowed, unreachable or answers with a non-2xx status, the request returns `422` with the reason on `endpoint` (for example `The endpoint returned HTTP 500.`). ## OpenAPI ````yaml /openapi.json post /webhooks/{webhook}/send-test openapi: 3.1.0 info: title: TryPost API version: 2.0.0 description: >- REST API for TryPost.
