get https://{instance}-api.private.fin.ag/v3/{customerId}/partnerdata/authsecret/disable/
Use the /AuthSecret/Disable endpoint if you are a client of Flinks and want to revoke access from a partner that you have previously granted access to.
This endpoint disables their AuthSecret so that they can no longer retrieve data through Flinks APIs.
To re-enable the AuthSecret, use the /AuthSecret/Enable endpoint.
