Assign Google Business Profile location to another profile

Connect a Google Business Profile location onto a DIFFERENT profile by reusing the OAuth grant from an already-connected Google Business Profile account, with no browser and no re-authorization. Built for agencies whose single Google account has manager access to many client locations and who run one profile per client: connect one location the normal way (browser OAuth), then bulk-assign the rest onto each client's profile via this endpoint. The path accountId is a SOURCE connected Google Business Profile account (the token holder); the body profileId is the TARGET profile, which may already hold other locations; assigning a location it already holds refreshes that account.


POST
/v1/accounts/{accountId}/gmb-locations/assign

Authorization

bearerAuth
AuthorizationBearer <token>

API key authentication: send your Zernio API key in the Authorization header, prefixed with Bearer.

In: header

Path Parameters

accountId*string

A source connected Google Business Profile account whose OAuth grant is reused.

Select Google Business Profile location

Complete the headless Google Business Profile flow by saving the user's selected location. The pendingDataToken is returned in your redirect URL after OAuth completes (step=select_location). Tokens and profile data are stored server-side, so only the pendingDataToken is needed here. Use X-Connect-Token header if connecting via API key.

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.

profileId*string

Target profile to connect the location onto.

selectedLocationId*string

The Google Business Profile location ID to assign (e.g. "locations/123").

googleAccountId?string

Optional but recommended. The Google Business Profile Account resource name ("accounts/123") that owns the location (from GET gmb-locations). When provided the location is resolved directly instead of by enumerating the account, required for accounts with many locations.
