Send a test webhook delivery

POST /api/v1/webhooks/test

API key required Base https://api.emailvalidator.ai 60 requests per minute per account

Enqueue a test webhook delivery to a URL you control. Useful for verifying that your endpoint is reachable and that signature verification works before running real validations.

The delivery arrives as event: "test" with data: { "message": "This is a test event." }, and is signed with the same X-Signature header — and the same account signing secret — as production events (t=<unixSeconds>,v1=<hex>; see components.headers.X-Signature for the verification recipe and the freshness window). So the secret you pin for production verifies a test event unchanged. It arrives at your URL within seconds.

The response returns the event_id the delivery will carry as its envelope id, so you can match the event your endpoint receives to the call that produced it.

Responses

202

Test event queued. · application/json

400

Missing or invalid callback_url. · application/json

401

Missing or invalid API key. · application/json

403

The API key authenticated but is not scoped for this endpoint (code: insufficient_scope). It is a 403 rather than a 401 on purpose — the credential is valid, so retrying with it can never help; a key holding the verify scope is needed. · application/json

429

Rate limit exceeded. · application/json

500

Unexpected server error. The body carries code internal_error plus a request_id to quote in a support request, and never any exception detail. · application/json

Standard error response shape used by all error status codes.

Field	Type	Description
status required	integer	HTTP status code mirrored in the body. example: 400
code required	string	Stable, machine-readable error code. Branch your code on this — never on the `error` text, which is prose and may be reworded at any time. example: invalid_email
error required	string	Human-readable error message. example: Invalid email format.
param	string	The request field the failure is attributable to. Omitted when the failure is not about one specific field. example: email
details	array of string · null	Optional per-field validation messages. Null when not applicable. example: ["email: required"]
doc_url	string	Link to the documentation for this error code. example: https://emailvalidator.ai/docs/get-started/errors
request_id	string	Correlation id for this request. Quote it in a support request — it is how a single call is found in the server logs. example: 0HNCV1TQ3PLRK:00000003
