Add new customers to user list

[Karan]

I have created and populated a com based audience list through Adwords api.

how can I add more customers in the same list through API.

I see the option to do it through dashboard but can't find a documentation for doing it through API

Hi Karan,

Thanks for reaching out. You could use the AdwordsUserListService.mutateMembers() to add members to an existing customer match list. This is an example code to create and populate a user list. You could get rid of these code snippets and set the existing userId in this line of code.

Thanks and regards,

with a 'ADD' operator in mutateMembers() will the new data get appended onto the existing customers in that list?

because 'SET' operator is not supported In this case.

P.S. I am using python client.
