List Google Business Profile locations

Returns Google Business Profile locations the connected account can access, plus the currently selected location. The list is bounded (see hasMore); for accounts that own many locations, use the search or filter query params to find a specific one instead of loading them all, or raise limit to enumerate an account with more than 100 locations.

List Pages with a linked Instagram account

Completes the `loginMethod=facebook_login` Instagram flow, i.e. "Instagram API with Facebook Login". After the user authorizes on Facebook, extract `tempToken` from the redirect params (headless mode adds `step=select_account`) and pass it here to list the Facebook Pages they manage. Only Pages that have a linked Instagram professional account are returned, so an empty array means the user has no eligible Page. Use the X-Connect-Token header if connecting via API key. Not used by the default `instagram_login` flow, which creates the account without a selection step.

selectedLocationId*string
Length1 <= length
googleAccountId?string

Optional but recommended. The Google Business Profile Account resource name ("accounts/123") that owns the new location (from GET gmb-locations). When provided, the location is resolved directly instead of by enumerating the account, which is required for accounts with many locations. Named googleAccountId to disambiguate from the path accountId (the Zernio account). The legacy field name accountId is still accepted for backwards compatibility.
