## Detail response

Reading one delivery adds `event`, `rawBody` and `attempts`. An event includes `id`, `type`, `projectId`, `environmentId`, `occurredAt` and JSON `data`. Each attempt records `id`, `attemptNumber`, `replayCount`, `status`, `signingSecretVersion`, `signatureTimestamp`, `httpStatus`, `errorCode`, `startedAt` and `finishedAt`.

Attempt status is started, succeeded, failed or abandoned. HTTP status and completion/error fields can be null.
