Using HTTP to Access The API

You can use an HTTP library in your environment to access the API. This is most useful for those environments that don’t already have a client library.

Content Negotiation

You can use either XML or JSON as the request and response format. Use the Content-Type header to specify the format of any request message and the Accept header to specify the desired output format

Paging

The number of results returned from many messages is limited to 200 records. If a web service response would have contained more than 200 records then it will include a field named NextPage with a link to the next page. You can follow the link to retreive the next page.
