Response Code=-1011 "Request failed: unsupported media type (415)

Question

I want to call API of "freshdesk" using AFNetworking. And that API is working perfectly from rest client.But I want to call that API from iOS application side using AFNetworking But I getting below error:

Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: unsupported media type (415)" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x7fd4a1579ed0> { URL: https://leotest.freshdesk.com/api/v2/tickets } { status code: 415, headers {

I think problem is that when I'm passed data in API

 NSDictionary *params=@{@"description":@"This is testing issue",
                               @"subject":@"Support needed..",
                               @"email":@"abc@gmail.com",
                               @"priority":[NSNumber numberWithInt:1],
                               @"status":[NSNumber numberWithInt:2]};

 [webServiceController PostWithHeaderUrlCall:@"https://test.freshdesk.com/api/v2/tickets" Param:params];

WebServiceController.m

-(void)PostWithHeaderUrlCall:(NSString *)IN_URL Param:(NSDictionary*) IN_Param
{

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    AFHTTPRequestSerializer *requestSerializer = [AFHTTPRequestSerializer serializer];
    NSData *basicAuthCredentials = [[NSString stringWithFormat:@"%@:%@",@"fsdwt52ewr5325wer5",@"x"] dataUsingEncoding:NSUTF8StringEncoding];
    NSString *base64AuthCredentials = [basicAuthCredentials base64EncodedStringWithOptions:(NSDataBase64EncodingOptions)0];
    [requestSerializer setValue:[NSString stringWithFormat:@"Basic %@", base64AuthCredentials] forHTTPHeaderField:@"Authorization"];
    manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"application/json"];

    manager.requestSerializer = requestSerializer;

    [manager POST:IN_URL parameters:IN_Param progress:nil success:^(NSURLSessionTask *task, id responseObject)
     {
         m_Status=1;
         self.dic_Response = (NSDictionary *)responseObject;
         [[NSNotificationCenter defaultCenter] postNotificationName:m_strPostMsg object:self];

     } failure:^(NSURLSessionTask *operation, NSError *error) {
         m_Status=0;
         self.dic_Response=[[NSMutableDictionary alloc]init];
         [self.dic_Response setValue:Time_Out_Msg forKey:@"message"];
         NSLog(@"%@",error);
         [[NSNotificationCenter defaultCenter] postNotificationName:m_strPostMsg object:self];

     }];

}

AFNetworking 3.0 use this code for pass data on server .

 NSMutableDictionary *params = [[NSMutableDictionary alloc]init];
 [params setValue:YOURV_VALUE forKey:@"description"];
 [params setValue:YOURV_VALUE forKey:@"subject"];
 [params setValue:YOURV_VALUE forKey:@"email"];
  [params setValue:YOURV_VALUE forKey:@"priority"];
[params setValue:YOURV_VALUE forKey:@"status"];

[webServiceController PostWithHeaderUrlCall:@"https://test.freshdesk.com/api/v2/tickets" Param:params];

-(void)PostWithHeaderUrlCall:(NSString *)IN_URL Param:(NSMutableDictionary*) _params
{
        AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:YOUR_URL]];
        manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];
    [manager POST:url parameters:_params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
            NSLog(@"response = %@", responseObject);
        if( _success )
        {
            _success( responseObject ) ;
        }
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
            NSLog(@"error = %@", error);
            if( _failure )
            {
                _failure( error) ;
            }
        }];
    }
    else{
        [Utility showAlertWithMessage:@"No Internet Connection"];
    }
   }
 }
