BrainerceSet the tags of an order
Replaces the order's complete internal tag list. Tags are for the store team: the customer never sees them, no email is sent when they change, and they are not sent to a sales channel. Send an empty list to clear them. Up to 100 tags of 100 characters, no commas; repeats that differ only in letter case are merged, and a tag takes the spelling the store already uses. Imported (view-only) orders can be tagged too.
Supports Idempotency-Key header for safe retries.
Admin API key (server-to-server). Issue via the dashboard at Settings → API keys. Plain-text key is shown once — store in a secret manager. Format: Authorization: Bearer brainerce_xxxxxxxxx.

Header Parameters
Client-supplied key (a UUID v4 is the recommended form, max 255 characters) that makes this mutation safe to retry.
- Replay window: 24 hours. The first response for a key is cached; a retry inside the window with the same request body returns the original status and body without re-running the handler.
- Reusing a key with a different body returns
409 Conflictwithcode: "IDEMPOTENCY_KEY_REUSED". The request fingerprint (method + path + body hash) is compared against the stored one; a mismatch is refused rather than served the old response. - Keys are scoped to the calling credential and store — two API keys may safely use the same key value.
- Error responses are cached too, so a retry of a request that failed validation returns the same 400 immediately.
- Sending this header on a
GETreturns400withcode: "IDEMPOTENCY_KEY_NOT_SUPPORTED"— GETs are already idempotent. - Support is per-route and this parameter is the authoritative signal: a key sent to a route that does not declare it is accepted and silently ignored.
length <= 255The order's complete tag list (internal, never shown to the customer). Up to 100 tags of 100 characters, no commas; repeats that differ only in letter case are merged. An empty list clears the tags.
