Hi Dhruv,
The Dynamic Re-marketing campaign needs to be created from the AdWords UI. Please refer to
this guide for more information on Re-marketing. Once the campaign is created, you may refer to
this guide which illustrates in detail about how to create a feed and how to associate this feed with a campaign. Code snippets in Java can be found
here. You may refer to
this code sample in C#.
Can you give this a try and let me know if you have any other questions.
Regards,
Bharani, AdWords API Team
