Authorizations

​
Authorization
string
header
required

Timbal API key. Obtain your API key from the Timbal platform settings. See Authentication for more information.

Path Parameters

​
org_id
string
required
​
kb_id
string
required
​
file_id
string
required
​
chunk_uid
string<uuid>
required

Body

application/json
​
content
string | null
​
embed
string | null

Text used for vector / full-text indexing. When content is provided and embed is omitted, embed is auto-set to the new content. Send an explicit value to keep an indexing-optimized variant distinct from the user-visible text.

​
page_end
integer<int32> | null
​
page_start
integer<int32> | null

Tri-state: omit to leave unchanged, send null to clear, send an integer to set.

Response

Chunk updated. Search results reflect the change after re-indexing completes (index_status field).

​
blocks
object
required

Source-document layout metadata (e.g. bounding boxes, page coords) when available. null for chunks created or edited by the user.

​
content
string
required
​
created_at
string<date-time>
required
​
embed
string
required
​
index_status
string
required

Indexing state. One of pending, indexing, indexed, failed. While not indexed, the chunk's contribution to search results may be stale.

​
kb_file_id
string
required
​
ordinal
string
required

Ordering key. Chunks in a file are returned in ascending ordinal order. Treat the value as opaque — placement on insert is controlled by after_uid / before_uid, not by setting ordinal directly.

​
revision
string
required

Optimistic concurrency token. Send back as If-Match: <revision> on the next mutation (PATCH / DELETE).

​
source
string
required

Origin of the chunk: parser, user_edit, or insert.

​
uid
string<uuid>
required

Stable per-chunk identity.

​
updated_at
string<date-time>
required
​
index_error
string | null
​
indexed_at
string<date-time> | null
​
page_end
integer<int32> | null
​
page_start
integer<int32> | null
