# Get one message

`GET /v1/messages/{id}`

- Authentication: required (Bearer token)
- Required scope: `messages.view`

Returns the aggregated detail for a single message (the same
`V1Message` projection as the list endpoint). Lookup is by the
SES-issued message id, not an internal UUID. Cross-org lookups and
unknown ids both return `404 not_found` — no information leak about
whether a message exists in another org. Detail lookups go further
back than your plan's analytics-retention window: up to 365 days of
message detail is kept regardless of plan tier. Very old ids will
eventually 404 once they fall outside that window.

## Path parameters

- `id` (string, required) — SES message id (the SES-issued string, not a UUID).

## Example request

```bash
curl 'https://api.sendops.dev/v1/messages/string' \
  -H "Authorization: Bearer $SENDOPS_API_KEY"
```
