Re: INVALID ID and empty trigger field when an adword was deleted.

Hi Daniel,

You may use AdGroupService.get operation to get all existing adGroup and pass the adGroupId on the TrafficEstimatorService. The same can be done for getting the existing criterion using AdGroupCriterionService.get operation.

Please let me know if it helps answer the question above.

Cheers,

Joyce, AdWords API Team
