| --- | --- | --- | --- |
| `id` | `string` | Yes | The id of the Newsletter. |
| `at` | `string` | No | A time or Version name: the record as it stood then. Unset: as it stands now. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `newsletter` | [Newsletter](/business/nouns/newsletter) | Yes | The Newsletter. |

## Effects
| Fact | Value |
| --- | --- |
| Action class | None: a read |
| Modes | `try`, `do` (default): a read runs at once |
| Idempotent | Yes: a read changes nothing |
| Undo | Nothing to undo: a read changes nothing |
| Emits | No Event: a read changes nothing |

## Refuses when
| Check | Error | Fix | Then call |

| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | None. |
