Required scope: TAGS_WRITE

​
Behavior

Pass tag keys (lowercase, slugified identifiers) — not display names. List available tags with GET /v2/api/tags to get the keys. Adding a tag that already exists on the item returns a 409 error with code TAG_ALREADY_EXISTS. No action is taken — the tag remains applied.

​
Idempotency

This endpoint supports the Idempotency-Key header. If a request succeeds and you retry with the same key, the stored response is returned without re-executing the operation. See Idempotency.
