# Put Work Channel Output Document

`PUT /work/channels/{channel_id}/outputs/{output_id}/document`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/work/channels/{channel_id}/outputs/{output_id}/document`
- Auth: HTTP bearer

Replace a linked document's body (Markdown, whole). Needs canvas-write authority in the channel.

`expectedUpdatedAt` makes the save conditional: 409 if the document changed since you read it.

## Path parameters

- `channel_id` string, required: Channel id or slug
- `output_id` string, required: Output id

## Headers

- `Authorization` string, nullable
- `X-Target-Org-Id` string, nullable

## Request body

- WorkDocumentBodyBody: A document's new body: Markdown, replaced whole.
  - `content` string, required
  - `expectedUpdatedAt` string, nullable: The `updated_at` the editor loaded. The save fails with 409 if the document has moved on.

## Response `200`

Successful Response

- ApiResponseWorkChannelPayload
  - `data` WorkChannelPayload, required: A Work channel, chat, output, task, decision or activity document, as the app returns it.
  - `pagination` PaginationMeta
    - `page` integer, required: Current page number (1-indexed)
    - `limit` integer, required: Items per page
    - `total` integer, required: Total number of items
    - `has_next` boolean, required: Whether there are more pages
    - `next_cursor` string, nullable: Opaque cursor for the next page; null when there are no more items. Pass it back as the `cursor` query param to fetch the following page without computing page numbers.
    - `total_available` integer, nullable: Search endpoints only: how many records really match, when known. Can be larger than `total`, which is capped at the 10,000 results that can be paged. For company search this is a distinct-company estimate. Null when unknown; absent outside search.
    - `total_is_lower_bound` boolean, nullable: Search endpoints only: true when more records match than `total` shows (the result set is larger than the 10,000 results that can be paged). Absent outside search.
    - `notes` string[], nullable: Search endpoints only: plain-language notes about the result, e.g. that more records match than can be paged, or that a reversed `between` range was put in order.
