# GET /v1/subscriptions/:id/events/:eventId

> Retrieve a single event by ID. Returns the full delivery history, current status, and the exact webhook payload that was sent to your endpoint.

Use this endpoint to inspect any single event in a subscription's delivery history. The response includes the current status, attempt and delivery counts, the last HTTP response from your endpoint, and the complete Standard Webhooks payload. This is the most direct way to investigate a specific delivery failure.
