You can create Service REST rules to expose the REST APIs that can be called by another application to invoke an action or to retrieve data from Pega Platform. You need a service package and a Service REST rule to create and expose a Service REST from your application.

1. In the header of Dev Studio, click CreateIntegration-ServicesService REST.

2. In the Service REST Record Configuration section, in the Service name field, enter a label for the Service REST rule.

3. In the Service package name field, press the Down arrow key, and then select the service package for the Service REST rule.

4. In the Service version field, enter the implementation version for the Service REST rule.

5. Create a new URI template:

   1. Click Build URI.

   2. In the Build URI Template window, click Add.

   3. In the URI component column, specify the name of the URI component.

   4. In the URI component type column, specify one of the following values:

      • Literal
      • Variable
      Note: The first component in a URI template must be a literal component. For more information, see URI template component requirements.

   5. Click Submit.

6. Click Create and open.

7. On the Service tab, configure the URL path parameters mapping, data transform, and other configuration options for your service.

   For more information, see Defining resource and processing details for a Service REST rule.

8. On the Methods tab, identify the activity that is called by each method in the service REST rule.

   For more information, see Service REST methods.
