Sending Composite Data through REST

Overview

This tutorial demonstrates how to send Composite Data Types via the POST method using Rest Service Integration.

Define the Rest Service 

1. Navigate to System > Integrations > External Services in the Portal, then select ADD REST SERVICE from the top Action bar.
2. From the Add REST Service window, define the Service Name and Service URL. 
   1. Click SAVE INTEGRATION.  
      
      
3. From the newly created Rest Service Folder, navigate to All > Add Method to Service. 
   
   
4. In the resulting pop-up window, provide a Name, and define the URL as "test."
5. Define the HTTP Method as POST and Service Content-Type as JSON.
6. Select Specify Below (Use {} for variables) from the Request Body Format dropdown. The Request Body is used to define the Composite Data Type between the two curly brackets. Define the Request Body as the following code snippet, then select OK.
   JSON

   {
   "namedsession": "{sessionID}", 
   "datastring": "{stringinput}"
   }

   
   

Design the Flow
