# Send test event

`POST /v1/webhook_subscriptions/{id}/send_test_event`

Dispatches a signed `ping.test` event to this subscription's URL through the same pipeline as real events. Useful for verifying your receiver's reachability and signature verification in any environment without creating a real business event. Test-event failures do not affect the subscription's health counters or trigger failure-notification emails.

## Path parameters

- `id` string, uuid, required

## Headers

- `Idempotency-Key` string, required

## Response `200`

The newly created webhook event. Poll its delivery via `GET /v1/webhook_deliveries?event_id={id}` for receiver status.

- EventResourceDto
  - `id` string, uuid, required — Unique identifier of the event. Matches the envelope `id` delivered in the webhook payload and is stable across subscription fan-out and retries.
  - `type` 'event', required — Resource type discriminator.
  - `event_type` 'payout.created' | 'payout.initiated' | 'payout.paid' | 'payout.failed' | 'return.initiated' | 'return.paid' | 'return.failed' | 'return.returned' | 'deposit.received' | 'conversion.created' | 'conversion.completed' | 'conversion.failed' | 'account_holder.active' | 'account_holder.closed' | 'ping.test', required — Event type.
  - `api_version` string, required — API version the event payload was rendered at. Stable across retries and redeliveries, and mirrored in the webhook envelope `api_version` field.
  - `created_at` string, date-time, required — ISO 8601 UTC timestamp when the event was created.
  - `data` object, required — Event payload. Shape matches the resource schema for `event_type`.
