We've provided documentation of API request parameters in an interactive format:
Request parameters are displayed in a web form that you can fill out and submit to try out the APIs. To use the interactive documentation:
1. Click on the name of the web service to expand the test client interface.
2. Fill out each required parameter (click app id & key to pre-populate with your credentials)
3. Send Request to see the actual JSON response. You will also be provided with a curl invocation including a pre-formatted REST URL. To see the XML response, replace the json in the URL with xml.
4. Please be aware that large responses may take a long time to pretty-print in your browser.
Note that you must provide valid application credentials when you submit requests through the interactive documentation. If you are signed in to your account, you'll be able to select your credentials from a pop-up when you enter the appId and appKey fields.
