Apparently with the API endpoints of projects and clients it is not possible to use integration_ext_id, integration_ext_type and integration_provider to integrate a third party app like Monday. These attributes are exlusivley for integrations developed by the Toggl team (Asana, Salesforce, Jira…).
It would be very helpful if these attributes could be updated with a PUT and POST request so it is possible to integrate other plattforms like Monday as well.
