I have received the requested information you provided privately on another thread. For better communication, I will respond in this thread.
Upon my investigation, I was not able to find the adGroupId you are using. Could you confirm that this adGroupId (63567506098) still exists in your account? You may confirm this by running the
AdGroupService.get() and see if the adGroupId (63567506098) is returned in this service. I asked this because upon checking from my end, it appears that this adGroup doesn't belong to any campaign and might have caused the issue why the keyword update is not working properly.
If it was not returned, could you change the adGroupId to a valid or existing one before doing your service call again? After changing the adGroupId and it still did not update your keyword, kindly provide the complete SOAP request and response logs that were generated by using the reply privately to author in this thread so I could investigate further. However, if it returns the specified adGroupId, kindly inform me the campaignId it belongs to so I could check on this further.
