Copy or clone a Campaign using API

[Emanuele Bragagnolo]

Hi!

I am trying to implement a functionality to clone an AdWords campaign using the API. Basically I want the same behavior of the CTRL+C and CTRL+V that is available in the AdWords UI with a deep copy of the campaign and of all the AdGroups contained in it.

The approach I am trying to use is to get all the campaigns data with CampaignService GET and then create a new campaign changing only some fields. 

I've found this old thread https://groups.google.com/forum/#!topic/adwords-api/rErEluYfpAQ , but It's not indicated a clear solution for this use case.

Because I want to clone all the campaign the response should contain all fields: where can I find the list of such fields?

for the moment I am checking this documentation https://developers.google.com/adwords/api/docs/reference/v201702/CampaignService 

At the moment I'm having some problems to include the AdGroups list inside the response

Best regards, Emanuele
