Updated:May 21, 2026

To effectively utilize the Marketing API, users must follow some key steps to set up their environment and gain access to the API’s features. This section outlines the prerequisites necessary for getting started.

Ad Account requirements

To manage your ads through the Marketing API, you must have an active ad account⁠.

Locating your ad account number can be done through the Meta Ads Manager⁠.

Log into Facebook: Start by logging into your Facebook account that is associated with your business. Access Ads Manager: Find Ads Manager in the drop-down menu in the upper right corner of your Facebook homepage or business page. Locate your ad account: In Ads Manager, click on the ad account Settings from the menu on the bottom left of the screen. View ad account information: In the Settings screen, your ad account number appears here along with other details such as your billing information and spending limits.
