When should I use the Delayed or Live Application Key?

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 with virtual currency.

• The Delayed App Key should be used for development purposes and any functional testing.  The key provides delayed Betfair price data. The delay is variable between 1-180 second snapshots.
