# Retrieve / update / detach a QR

> GET, PATCH, DELETE /web-tracking/sites/qrs/{pk}/

Manages a single tracking-site/QR attachment. `DELETE` detaches the QR Code from the tracking site — it does not delete the QR Code itself.

<Note>
  Unlike every other endpoint in this module, the path here is `sites/qrs/{pk}/` rather than `sites/{site_id}/qrs/{pk}/` — the attachment `id` alone identifies the record, scoped to your account rather than to a specific site in the URL.
</Note>

<ParamField path="pk" type="integer" required>
  Attachment ID, from [List QR attachments](/api-reference/management-api/web-tracking/qrs-list-create).
</ParamField>

<ParamField body="is_active" type="boolean">
  Pause/resume the attachment (PATCH) without detaching it.
</ParamField>

<RequestExample>
  ```bash cURL Detach theme={null}
  curl --request DELETE \
    --url 'https://api.scanova.io/web-tracking/sites/qrs/2/' \
    --header 'Authorization: YOUR_API_KEY'
  ```
</RequestExample>

`204` on detach, `404` if `pk` doesn't belong to a site owned by this account.

    The complete Scanova Management API — every endpoint available at
    api.scanova.io (QR codes, folders, tags, leads, forms, analytics, plans,
    shared users & roles), plus the token-creation and usage-stats endpoints
    used to authenticate against it. Every path and request/response shape below
    was verified live against a real API key and the actual running backend
    (Phase 7, 2026-08-16) — not guessed from reading urls.py alone.

      description: >-
        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.
