- Apply tags to many QR Codes — the bulk equivalent.
- List tag names — the existing tag names to choose from.
- Detach tags — remove a tag across the whole account.
- QR Manager overview — the quotas, role permissions, and Trash model shared by every endpoint in this module.
- Management API overview — the auth scheme and quota rules that apply to this endpoint.
Authorizations
Send your Management API key as the raw value of the Authorization header — no "Bearer " or "Token " prefix, and no other characters. Example: Authorization: 401f7ac837da42b97f613d789819ff93537bee6a. A header containing more than one space-separated part is rejected outright. Requests also require the request's Host header to be the management API host (e.g. api.scanova.io) — the same key sent to the regular API host will not authenticate.
Path Parameters
The QR code's qrid — the opaque public identifier returned by the list endpoint, not the numeric id.
Response
Tags updated.
