# Update Content Chunk

`PATCH /api/content_chunks/{chunk_uuid}`

## Request

- Base URL: `https://api.regdoor.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.regdoor.com/api/content_chunks/{chunk_uuid}`
- Auth: HTTP bearer

Update an existing content chunk.

Updates the text, embedding, or tags of an existing chunk. Only provided
fields will be updated. The actor is taken from X-Regdoor-Actor-* headers
set by content-proxy, not from the JSON body. This API trusts any caller
that already holds the main-api/admin machine scope. It does not check
that the header matches a person.

## Path parameters

- `chunk_uuid` string, uuid, required

- `X-Regdoor-Actor-Email` string, nullable
- `X-Regdoor-Actor-Id` string, nullable
