The OpenX API platform is the easiest way for you to access and manage claim and eligibility data in the OpenX database. Before you start developing, here are a few things you need to know:

• Getting Started:  Application IDs and Shared Secret Keys
• Get an Application ID: Your Application ID gets you onto the OpenX platform and lets you access the sandbox for testing.
• Get data in XML or JSON: By default, the OpenX API platform sends data to you in XML format. But by adding a /JSON/ to the URL, we will serialize your results to JSON. You can find more information in our JSON overview.
• By default, we limit your application ID to 1000 calls per day. Need more? No problem, let's talk.
