Team,

We are having a clarification related to Calling Campaign Management REST APIs using C#.

POM Version: 3.1.1

With POSTMAN, we are able to trigger the methods and getting the response for the request. But while we trying to invoke the same using C#, we are getting 403 Forbidden Exception. This is happening for both GET and POST Methods.

Could you please help us on this.

Please find below the snippets:

GET Invocation:
bool bResult1 = GET("https://192.168.31.175/VP_POM_Service/v2/globalconfig/name/WeekEndDays","siva","siva@123", out postBody);

POST Invocation:

string WSURL = "https://192.168.31.175/VP_POM_Service/v2/campaigns";
Zoneepmlist zoneepmlist = new Zoneepmlist("default", new string[] { "EPM" });
Zoneepmlist[] arrayZoneepmlist = new Zoneepmlist[] { zoneepmlist };
Campaign reqBody = new Campaign(campaignName, campaignDescription, "InfiniteWithoutContacts", campaignStrategy, arrayZoneepmlist, "false");
string json = JsonConvert.SerializeObject(reqBody);
string postBody = string.Empty;
//log.Debug("[SetTwilioRecordingDetails] URL = " + WSURL + " Request " + json);
bool bResult = POST(WSURL, json, out postBody);
var Result = JsonConvert.DeserializeObject<CampaignResponse>(postBody);
//log.Debug("[SetTwilioRecordingDetails] Response - status is " + Result.result);

Console.WriteLine(Result.campaignID);
