These tokens, which must be URL- and filename-safe base64 strings, are created by the user, with UUIDs recommended. A session begins with an Autocomplete (New) call and ends with Place Details (New) or Address Validation. Each session may include several Autocomplete (New) queries. Once terminated, a new token is required. Omitting or reusing a token results in individual billing for each request.\n"]]
