Hi Alex, Since there are duplicate elements in the upload when trying to add the same extension setting object to multiple campaigns, I would recommend creating the extension setting separately using CampaignExtensionSettingService (rather than a dependent operation), fetching the feed ID and feed item ID from the extension and using these IDs when trying to add the extension setting to multiple campaigns. This would also help you in the case where the sitelink already exists and you do not want to create duplicates.
Referring to the Batch Jobs <https://developers.google.com/adwords/api/docs/guides/batch-jobs> documentation, Temporary IDs <https://developers.google.com/adwords/api/docs/guides/batch-jobs#using_temporary_ids> allow you to reference the result of an ADD operation from the previous operation in the same batch job. However, you need to ensure that the operation that creates a parent object comes before the operations that create its child objects. In your case, the situation becomes a little different, as explained below: *Expected Scenario:* When you define an extension_setting object with a feed item ID of -5, you are assuming the object to hold this value for *both *(or all) operations where this extension_setting object would be applied. *Actual Scenario:* During creation of the first campaign extension, the extension setting is created as a *dependent* object of the first campaign extension setting operation (and not the other way around). As a result, when the second operation executes, the original extension setting object is now treated as a duplicate. Please let me know if you are facing issues when creating extension separately and re-using them in the batch job.
