Updates an instructor using PUT. Only the fields you send are changed; omitted fields are left unchanged.

To disconnect an instructor from an admin user, send idUser with an empty value (e.g. idUser=).

Request

For every API request you make, you'll need to present the API access key in the HTTP Header as X-API-Key to be authenticated.
