Hi,
The first answer provided by Sreelakshmi in the forum thread you linked is still valid. Since there is still no direct feature that would clone an entity (e.g. campaigns, ad groups, etc.), then you need to follow the steps below (for copying a campaign and its dependencies) :
- Use CampaignService.get() method to get the specific campaign with fields that you want to copy from.
- Using the returned object in the first step, make necessary changes like changing the campaign name and then use that object as parameter in CampaignService.mutate().
- Since the step 2 only creates a new campaign, and not its dependencies like ad groups and criterion, then you need to use the service of each entity (e.g. AdGroupService, AdGroupCriterionService, etc.) to copy these entities and repeat steps 1 and 2 for each service.
As for your concern if we have a full list of objects/entities that you need to copy from a campaign, we only have a
guide for the object hierarchies that you can refer from.
Let me know if you have further clarifications.
Thanks,
Vincent
