Update Item

PATCH /items/{id}

Update an item (only the fields sent)

Scope items:write; role permission inventory.edit.

Request

PATCH https://example.com/api/index.php/v1/nextinventory/items/{id}

Parameters

Name Type In Required Description
id integer path Yes (min 1)
Idempotency-Key string header No Optional. Any unique string (1 to 191 printable ASCII characters, no spaces; a UUID is ideal). The request runs once: a retry with the same key gets the first response back, with the header Idempotent-Replayed: true, instead of running again. Keys are kept for 24 hours per token. 409 IDEMPOTENCY_IN_PROGRESS while the first request is still running; 422 IDEMPOTENCY_KEY_REUSED if the key comes with a different request. A 5xx answer is not kept, so it can be retried with the same key. (min length 1, max length 191, pattern ^[\x21-\x7E]+$)
If-Match string header No Optional. The ETag from your last read of this record. The change is made only if the record is still that version; otherwise 412 PRECONDITION_FAILED and nothing changes, so two systems editing one record cannot silently overwrite each other. * matches any existing record.
