# Remove websites from a notification configuration

POST https://api.modulards.com/api/public/v1/alerts/{alert_id}/sites/detach
Content-Type: application/json

Removes the websites you list in `sites` from a notification configuration. It is the counterpart of "Add websites to a notification configuration" and answers the same way.

`meta.status` is `applied` when at least one website was removed and `skipped` when none was. Websites that cannot be processed are reported in `meta.skipped`, each with a `reason_code` and a message, and do not fail the call. A website is skipped as `ALREADY_APPLIED` when it is not in the configuration, and as `PERMISSION_DENIED` (with a null `site_name`) when your token cannot reach it; a member who reaches only some websites leaves the others in place.

**Body**
- `sites` (array of integers, required): ids of the websites to remove, 1 to 50. Each must be an existing website.

**Errors**
- **422**: `sites` is missing, empty, has more than 50 ids or contains an id that is not a website. The body is checked before the configuration, so a configuration of another organization answers 404 only when the body is valid.
