Connect

List GBP locations

For headless flows. Returns the list of GBP locations the user can manage. Use pendingDataToken (from the OAuth callback redirect) to list locations without consuming the token, so it remains available for select-location. Use X-Connect-Token header if connecting via API key.

GET
/v1/connect/googlebusiness/locations

Authorization

AuthorizationBearer <token>

API key authentication - use your Zernio API key as a Bearer token

In: header

Query Parameters

profileId?string

Profile ID from your connection flow. Required for auth validation when provided.

pendingDataToken?string

Token from the OAuth callback redirect. Preferred over tempToken because it preserves server-side token storage. One of pendingDataToken or tempToken is required.

tempToken?string

Legacy. Direct Google access token. Use pendingDataToken instead when available.

search?string

Free-text search on the business name, applied server-side by Google. Use this for accounts that own many locations (the response is bounded, see hasMore) so the user can find a specific location without loading the full list.

filter?string

Raw Google Business Information API filter expression (advanced; takes precedence over search). Supports fields such as title, storeCode, storefront_address.postal_code, labels and categories, e.g. storeCode="LH279411". See Google's "Work with location data" guide.

Select GBP location

Complete the headless GBP 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.
