# Create an entity narrative

**POST** `/entities/{entity_id}/narratives`

Append a free-form note to an entity's customer file, such as the context a reviewer records while collecting CIP/CDD documentation. Narratives are append-only: they cannot be edited after creation, only deleted as individual records.

### Path Parameters

- `entity_id` `string` _(required)_ — Unique identifier for the entity.

### Body Parameters

- `body` `string` _(required)_ — The free-form text of the narrative. Maximum length is 30,000 characters. Narratives are append-only and cannot be edited after creation.
- `related_document_id` `string` — Optional ID of a document this narrative references. The document must belong to your platform.
- `related_field` `string` — Optional entity field path this narrative is about, e.g. `last_name` or `associated_persons.control_person.address`.
