Every Facebook Page the connected Meta user administers, read live from Meta, each resolved to its linked Instagram Business account (ig_user_id / ig_username, with has_instagram as the quick flag). is_current marks the Page this shop is connected through.

The Instagram link matters beyond display: Partnership ads and creator whitelisting both run through the Page's IG account, so a Page with has_instagram: false leaves the connection functionally incomplete even while /meta-ads/status reports connected: true. Single shop only.
