Hi, Thank you for reaching out to the Google Ads API support team.
Can you confirm whether you are trying to upload the audiences to an already created audience using the customer match in the Google Ads API? If yes, you can absolutely use the Google Ads API (specifically Customer Match) to upload data to an existing audience and target only that audience. You need to use the Google Ads API with the OfflineUserDataJobService to manage your Customer Match audience data. First, you must identify your existing audience. While you know the name, the API requires the resource name of the existing CustomerMatchUserList. You can query the user_list resource to find the ID based on the name. You can initiate an upload process by creating a new OfflineUserDataJob. When creating the job, you explicitly link it to your existing audience by setting the CustomerMatchUserListMetadata field and providing the resource name of the existing CustomerMatchUserList. This ensures the data goes only to that specific list. You send the customer data (hashed emails, phones, etc., usually in batches) using AddOfflineUserDataJobOperations. The operation is to append to the existing list. You can run the job to process the data by using RunOfflineUserDataJob. I would recommend you to refer to this documentation for more detailed information. You can follow the best practices in mind when designing your Customer Match integration.
