# Update documents

Applies an ordered sequence of field-level patch operations to one or more existing documents. Patches are applied in the order supplied; if any patch in the sequence is invalid, the entire update for that document is rejected.

Request:
updates   - List of documents to update. Each entry includes:
id          - The document ID to target. Either id or externalId must be supplied.
externalId - The external system ID to target (alternative to id, useful when the document was created with an externalId for cross-system referencing).
patches     - Ordered list of patch operations. Field paths use forward-slash notation matching the document's field structure (e.g. /name or /metadata/status). Each patch is one of:
Add(path, value)     — sets a field that does not yet exist.
Remove(path)         — removes the field at the given path.
Replace(path, value) — overwrites an existing field's value.

Response:
ids   - IDs of the documents that were successfully updated.
