1. Go to your business manager at business.facebook.com
2. There should be a notification from Criteo requesting access
(if there's no request pending, please contact our team and we'll send one over).
3. Either click the notification, or click on the “Requests” sub header which should show a red 1 next to it.
4. On the next page, accept the request.
5. If you want to confirm our access, click into the “People and Assets” subheader, then “Pages” on the left side, and then the page we requested access to. You should see Criteo under the “Accepted Partners” group with a check mark next to “Page Advertiser”.
