Developing
The topics in the Developing section describe tasks performed by an application developer.
Web services and WebSphere Commerce
A web service is an interface that describes a collection of operations that are accessible through the network by using standardized XML messaging.
Representational State Transfer (REST) services
WebSphere Commerce uses Representational State Transfer (REST) services to provide a framework that can be used to develop RESTful applications on several platforms. These platforms can include web, mobile, kiosks, and social applications.
Preview for RESTful applications
The web services framework and REST services framework can leverage the use of preview tokens to allow business users the ability to preview content in RESTful applications outside of the store's web module. For example, you can make customizations for your Android smartphone native reference application to preview actions in your application with the preview options specified in the preview token.
Enabling preview support for RESTful applications
If you are using REST services and customizing a service client to preview content, you must modify the wc-server.xml configuration file to enable <ServicesPreview>. Enabling services preview allows your service client to connect to the WebSphere Commerce server to process BOD and REST service requests and responses with a preview token.

Feature Pack 6

Enabling preview support for RESTful applications

If you are using REST services and customizing a service client to preview content, you must modify the wc-server.xml configuration file to enable <ServicesPreview>. Enabling services preview allows your service client to connect to the WebSphere Commerce server to process BOD and REST service requests and responses with a preview token.

Enabling services preview also enables preview token generation requests to be processed; otherwise, the following error message will be returned from REST:

Services preview support is not enabled.

About this task

Preview support for RESTful applications is enabled by default in Feature Pack 7 and 8. Complete this task if you are using Feature Pack 6, or have previously disabled this feature within the WebSphere Commerce configuration file.

Procedure

Open the WebSphere Commerce configuration file
Within the <InstanceProperties> tag, add the following code:
