Let's say you are developing a browser-based app that your clients can use to create and run ads on Facebook. To access your clients' Ad Accounts, Campaigns, and Product Catalogs through the Marketing API, your app needs to be approved for the Ads Management Standard Access level and the ads_management, pages_read_engagement, and catalog_management Permissions.
After adding and configuring the Marketing API product, implementing Facebook Login, and confirming your app uses data in accordance with our Platform Policy, you begin the App Review process so you can take your app Live.
You sign into your App Dashboard and click App Review, then click Permissions and Features.
You search for "ads_management" to locate ads_management and Ads Management Standard Access, and request them both. You locate and add pages_read_engagement and catalog_management, and continue the request.
Now you describe how your app will use the data to which you are requesting access. In the Requests section, you click Edit Request.
Click the arrow icon in the Tell us how you'll use ads_management row.
Provide a general description of what your app does, then explain how the ads_managemen` Permission will help the people using your app. You enter the following description in the Tell Us Why Are Requesting ads_management section:
"The app is used by advertising account managers to set up ad campaigns, manage ads, and view reports that show metrics about ads. The ads_management permission allows them to get data about existing Facebook ads and to create ads. Without this permission, the app can't function."
In the Upload Screencast section, you click Upload File and upload a short, minute-and-half screen recording of a user signing into your app and exploring the user interface in the same way you described in your instructions.
You upload your screen recording, which shows a user following your instructions.
You then save your changes and repeat these steps for the pages_read_engagement and catalog_management Permissions and the Ads Management Standard Access level descriptions. Because your screen recording shows how both Permissions and your Feature are used, you use the same screen recording for all of them.
To complete the app verification process, click the arrow in the Provide verification details row.
Click Yes to agree to Facebook Platform Policy.
Then, enter instructions that a submission reviewer can follow to verify that your app uses the Permissions and Features you have requested in the way you have described. You also indicate when this happens in the screen recording that you have uploaded.
"To see how our app uses these permissions:
The accompanying screencast shows ads_management being used whenever the user displays ad information or a new entity is saved: for example, at 00:10, 00:18, 00:32, 1:12, and 1:19.”
You have supplied everything a reviewer will need to verify that your app uses the Permissions and Access Levels in an approved manner, so you click Submit For Review.
