It might be easier to ask which ones we do NOT support.

Our services are built API-first with a focus on data quality and ease of integration. 
We support REST, SOAP, GET and POST requests over HTTP/S outputting in XML and JSON formats.

We test our services with:

• ASP
• ColdFusion MX
• PHP
• Java (Apache SOAP and Apache Axis)
• Perl (SOAP::Lite version 0.52)
• C# in MS Visual Studio .NET
• Ruby on Rails
• Apex (for Salesforce)
• Python
• and the list continues to grow

Our API web services are compatible with all major programming languages and we have over 200 pieces of sample code (both snippets and full solutions) available to help with your integration.

Our APIs are built for developers, by developers.  If you don't see what you are looking for, let us know.
