In order to use the Betting & Accounts API, you need to have an Application Key. The Application Key identifies your API client. Two App Keys are assigned to a single Betfair account, one live App Key and one delayed App Key for testing.
You must pass the Application Key with every HTTP request. You do this by setting the HTTP header with the value of the key assigned by Betfair.
