Create Azure Function Code which requests a GET Rest API

Please create c# code which we can upload to azure functions and run once per hour. The code should authentificate with a given API-Key and API-Secret using the provided POST-Method. After authentication your code has to call one GET endpoint and load the json result into three azure sql-tables. The API is described here: [login to view URL] The endpoints you will have to use are: POST: /developer/sign-in - for authentification GET: /time-entries/{stoppedAfter}/{startedBefore} - for data loading
