# Read a test sink delivery

`GET /v1/test-sinks/{sinkId}/deliveries/{deliveryRecordId}`

## Request

- Base URL: `https://docs.greatwait.dev` (the document declares no server; this is the origin it was published from)
- URL: `https://docs.greatwait.dev/v1/test-sinks/{sinkId}/deliveries/{deliveryRecordId}`
- Auth: one of:
  - HTTP bearer
  - HTTP bearer and API key in header `Greatwait-Environment` and API key in header `Greatwait-Project`

Reads one recorded delivery including the exact bytes that arrived, truncated at the published cap with the original length stated. This is the one place a callback body is readable, and it is narrow on purpose: a test environment only, the creating authority only, a single record rather than a listing, and never a log. The signature is included because a MAC is not secret and comparing it against a locally computed one is how a body-mutation bug is found; no signing key appears in this shape.

## Path parameters

- `sinkId` string, required
- `deliveryRecordId` string, required

## Response `200`
