Hi Gaddy,
Thank you for contacting support, could you confirm if the output that you retrieved from the TargetingIdeaService is similar to the Keyword Planner 's output when you use the exact same parameters?
Also, could you provide to me the complete SOAP request and response logs that were generated so I can further investigate from my end? You may reply using the Reply privately to author option.
Thanks and regards,
Peter
