Granting Access To Your Facebook Ad Account

Once you provide your Facebook Ad ID, we will send an access request. You will find the notification under the alert bell. If you do not see the alert, go to your ads manager directly to find the request. Please grant full control access for us to be able to manage the ad properly.
