# Retrieve a webhook delivery

`GET /webhook-deliveries/{id}`

## Request

- Base URL: `https://api.cavuno.com/v1`
- URL: `https://api.cavuno.com/v1/webhook-deliveries/{id}`
- Auth: HTTP bearer

Returns a delivery including its most recent attempt history (≤500 attempts, ascending by attempt_number). `attempt_count` is authoritative: when it exceeds `attempts.length`, older attempts were truncated. Never exposes lease fields or serialized event bodies.

## Path parameters

- `id` string, required: The webhook delivery ID.

## Response `200`

Successful response. `attempts` holds the most recent ≤500 attempts in ascending order; `attempt_count > attempts.length` implies truncation.
