If your tenant has Dynamic Client Registration enabled, you can let third party applications use a connection by promoting it to a domain level connection. Domain level connections are enabled or disabled for all applications in a tenant. You can promote a connection to domain level using Auth0’s . Make a PATCH call to the Update a Connection endpoint. Be sure to replace CONNECTION_ID and MGMT_API_ACCESS_TOKEN placeholder values with your connection ID and Management API , respectively.
