Send a signed webhook.test event now and return the result inline. Use this to verify signature verification end to end before relying on real events. The attempt is recorded in the endpoint’s delivery log but is purely diagnostic: it never counts toward the failure streak, never auto-disables the endpoint and is never retried. A receiver that rejects the event still returns 200 here with ok: false and the status code it responded with, because the CALL succeeded even though the DELIVERY did not; a disabled endpoint is still testable.

Authorization

This route requires the write scope. A missing or invalid credential returns 401 authentication_error. A valid credential without the scope returns 403 permission_denied, and the problem body names the exact scope required.

Headers

These are request conventions the contract does not declare as parameters, so they do not appear in the schema tables below.

Header	Applies	What it does
`X-Exo-API-Key`	Required	Your Exo API key, `exo_<env>_<token>`. `Authorization: Bearer exo_...` is accepted as an alternate.
`X-Exo-Subject`	Not applicable	This route is not subject-scoped.
`Idempotency-Key`	Not honoured	This route does not replay: a diagnostic send is meant to happen every time you ask for it.
`X-Request-Id`	Response	Returned on every response, including `204`s. Quote it in a support request.

Success responses

Status	Meaning
`200`	Successful Response

Errors

Status	Code	When
`400`	`invalid_request`	Malformed request, for example an invalid cursor.
`401`	`authentication_error`	Missing or invalid credentials.
`403`	`permission_denied`	Missing scope, or an unprovisioned subject selector.
`404`	`not_found`	The resource does not exist, or is not visible to this caller.
`409`	`conflict`	A conflict with the current state of the resource.
`422`	`validation_error`	The request was understood but failed field validation.
`429`	`rate_limit_exceeded`	Rate limit exceeded. Retry after the Retry-After interval.
`503`	`service_degraded`	A dependency is temporarily unavailable. Safe to retry.

Every error is an RFC 9457 application/problem+json body carrying a stable code, a requestId, and a suggestedAction where Exo has one. See Errors.

Notes

A test never counts against the endpoint. It is recorded in the delivery log but never contributes to the failure streak, never auto-disables and is never retried.
A receiver that rejects the event still returns 200 here, with ok: false and the status it responded with, because the call succeeded even though the delivery did not.
