Test a connector URL

Test whether the platform can reach a given endpoint, behind the Test connection action used before creating a data source. The request is made from the server rather than the browser. Requests to private or internal network addresses are blocked.

Sends a GET to the URL from the server and returns the status and the start of the body. Rate limited to 20 calls a minute.

Notes.

• A URL that cannot be reached is not an HTTP error: the answer is 200 with ok: false, status: 0 and error.
• A blocked private or internal address answers 400 with the { data: { ok: false, status: 0, error } } body, not the usual error body.
