Hi Kishan,
I work with Peter and let me provide support to your concern.
With regard to the sample REST API for adding members to a user list, this
guide may help you here. Let me know if you have question on the provided guide.
As for how long it will take to populate the UserLists with the user's emails, it takes 6 to 12 hours for a list to be populated with members, so you'll most likely
see an "In Progress" status (on the Google Ads UI) if you upload to an audience list more frequently than once every 12 hours. However, it will sometimes take 48 hours according to this
document. With this, I would suggest to wait for at most 2 days and if it is still not populated with the said period, then you may provide the complete
request and
response logs with
request ID generated on your end to investigate and to address it.
Regards,
