# testWebhookEndpoint — Postify API

`POST /v1/webhook-endpoints/{id}/test`

Send a test delivery. Sends a synthetic `webhook.test` event to the endpoint, signed exactly like a real delivery (Standard-Webhooks headers over the raw body). Use it to verify your signature handling before subscribing to real events. Disabled endpoints return 409 `resource_conflict`.

- Required scope: `webhooks:write`
- Auth: `Authorization: Bearer postify_live_…` or `x-api-key` header

## Parameters
