 \"error\": {
  \"errors\": [
            


        

Answer 1

It was missing the header field X-Ios-Bundle-Identifier.

NSString *bundleID = @"com.yourCompany.yourApp";
//...define request as above
[request setHTTPMethod:@"GET"];
[request setValue:bundleID forHTTPHeaderField:@"X-Ios-Bundle-Identifier"];
