What is an Application Key?

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.

  2. Select the createDeveloperAppKeys operation from the list of Operations on the top left hand side of the demo tool.

We are aware that when using some browser versions to create App Keys the Demo Tool throws an UNEXPECTED_ERROR when requesting createDeveloperAppKeys. Using an alternative browser/s should resolve this problem.

You should also ensure that your Application Name is unique as attempts to create a duplicate Application Name will return an APP_KEY_CREATION_FAILED error response.

Live & Delayed Application Keys Usage

The createDeveloperAppKeys service will assign two Application Keys (App Keys) to your Betfair account.

One 'Live' Application Key and one 'Delayed' Application Key. A Delayed Application Key is displayed as 'Version 1.0-DELAY' via createDeveloperAppKeys/getDeveloperAppKeys

Key points:

  • Upon creation, the Live Application Key will be inactive.

  • The Delayed App Key operates on the live (production) Betfair Exchange and not a testbed/sandbox environment.
  • The Delayed App Key should be use for development purposes and any functional testing.  The key provides delayed Betfair price data. The delay is variable between 1-180 second snapshots.

  • The Delayed App Key must also be used in simulation/practice applications where the facility to bet into live Betfair markets is not available.
  • The Delayed App Key does not return traded volume data 'totalMatched' or EX_ALL_OFFERS via listMarketBook.
