Delete the integration between Pixop and Mimir tenant

Deletes the integration and performs the following clean‑up steps:

• Removes the Pixop webhook.
• Cancels all ongoing jobs.
• Removes Pixop custom actions in Mimir.
• Deletes Pixop metadata and Pixop videos created via the integration.
• Deletes the tenant mapping.

Notes:

• Videos in Mimir are not deleted - only their Pixop related metadata is deleted.
• The Pixop subtype and Pixop Status option list in Mimir remain untouched.
• Pixop processing configurations in Pixop are not deleted.

If no integration exists, or the provided Pixop key has no access to the team, a 404 is returned.
