Feng-GUI has an open web Application Programming Interface (API for short).
This means that you can write your own program to integrate Feng-GUI technologies and services
in new and different ways.
For example, you could automate usability testing, Optimize your Ad placement , create a Photoshop plugin, etc'.

Anyone can write software to do cool stuff with available Feng-GUI technology via our API.
Here's how to get started:
1. Read the API documentation below. Don't forget to send us some feedback.
2. Request for an evaluation account. email to:
3. After you have learned how to use API and you have your authentication credentials, build your own application.

To perform an action using the API, you need to invoke a SOAP request to its endpoint specifying a method and some arguments, and will receive a formatted response.
SOAP format (recommended)
XML-RPC format. obsolete. do not use this format.

User Authentication
Feng-GUI services required HTTP Basic authentication for all methods.
Roles
A Role indicates the levels of permissions a User have while operating a method.
Your account is associated with one or more Roles, and it is most likely that your Roles depends on the Feng-GUI partnership level you have.
