1. In the navigation pane of Postman, expand the cases folder, and then click Create new Incident - success.
   
2. Click the Body tab, and then enter the following JSON code:
   {
       "content": {
            "pyDescription": "Description"
       },
       "caseTypeID": "SL-TellUsMore-Work-Incident",
       "parentCaseID": ""
   }
3. Click Send to send the DX API request.
   
4. Toward the bottom of the request page, analyze the JSON response data objects returned by the DX API:
   1. Review the caseInfo object and note the case ID.
      
   2. Review the relatedCaseTypes object.
      
   3. Review the assignments object.
      The assignments object in the API response provides information about the Assignments created as part of the Case. It can include details such as the Assignment ID, the name of the assignee, the deadline for completion, and any associated data or attachments.
      
   4. Review the availableChildCaseTypes object.
      
   5. Review the availableActions object.
      The availableActions object that returns in the response of Create DX API is a list of Actions that users can perform on the created work object. These Actions are defined in the Case Type and can include options such as submitting the work object, saving it as a draft, or canceling it.
      
   6. Review the stages section: 
      In Pega DX API, the stages object in the response for Case creation refers to the Stage of the Case where the newly created Case currently resides. A Stage in Pega Platform™ represents a logical division of a Case where a specific set of Actions or Tasks are performed. Each Stage typically has a set of Steps or Assignments that must be completed before the Case can move on to the next Stage. When you create a Case with the Pega DX API, the response includes a Stage object that provides information about the current Stage of the Case. This object might include properties such as the Stage name, ID, status, and other details about the current Stage. This information can be useful for tracking the progress of the Case and determining what Tasks or Assignments need to be completed before the Case can move on to the next Stage.
      
5. In the nextAssignmentInfo object, copy the Assignment ID returned by the DX API (for example, ASSIGN-WORKLIST SL-TELLUSMORE-WORK I-1!CREATEFORM_DEFAULT) for the next task.
   
6. Return to App Studio, preview the application, and then open the TellUsMore - BO Portal.
7. Click Incidents, and then confirm that the newly created Case is displayed on the landing page.

      For example, ASSIGN-WORKLIST SL-TELLUSMORE-WORK I-1!CREATEFORM_DEFAULT.
      
4. Click Save, and then click Send.

   4. In the actionID row, enter DetermineCategory.
      
4. Click Save, and then click Send.
5. Review the JSON response object.

3. In the central work pane, open the Params tab, and then modify the query param values:
   1. In the viewType row, enter none.
