Update details of locations you already have (name, label, address, city, postal code) from a spreadsheet, matched to each location by its id. It does not create new locations. Each matched row replaces those values, and a blank store_id or address cell clears that value. If any row fails the checks, nothing is updated and the response is 400. The columns are listed on the guide page.

Prerequisites: a spreadsheet with one row per location (location_id, store_name, store_id, address, city_name, state_code, zip_code, country_code).

Authentication: Account token. Only locations in your own account are matched; any other token gets 403.

Rate limit: none.
