Google Business Profile

Get attribute metadata

Returns metadata about which Google Business Profile attributes are available for a location or business category. Use this endpoint to discover valid attribute names, value types, and allowed enum values before reading or writing via gmb-attributes.

Two mutually exclusive query modes:

Location mode: pass locationId (or rely on the account's stored selectedLocationId). Google returns attributes valid for that specific location.

Category mode: pass categoryName (must start with categories/) and regionCode. Google returns attributes valid for that category across the given region. languageCode is optional in category mode.

Both modes support pageSize and pageToken for pagination.

GET
