A Json API key is a unique code that identifies and provides access to your affiliate reporting. For example, if you enter your iTunes Json API key in your Linkfire board settings, we will be able to provide you with your iTunes sales insights directly within the Linkfire suite.
You can locate your Json API key inside your affiliate dashboard through Performance Horizons Group. Once you have your key, enter it into the corresponding field in your Linkfire board settings. Note that it takes up to 30 minutes for commissions on sales to be registered by iTunes.
