Hi Morteza, The configuration is almost fine, here's what you need to do to make calls to sandbox.
1. Run GetAllCampaigns.cs. This initializes the sandbox with 5 test accounts, but since you haven't added any campaigns, you will get an empty list. 2. Run GetAccountHierarchy.cs. This will give you the sandbox account structure and the customer ids of the 5 newly created accounts. 3. Pick any one of those customer ids, uncomment the ClientCustomerId field in your App.config and put the value there. 4. Now run AddCampaign.cs. It should work fine. Let me know if you have more questions. Cheers, Anash P.
