About field masks
For Place Details (New),
Nearby Search (New), and
Text Search (New), use the FieldMask header in
API requests to specify the list of fields to return in the response. You are
then billed at the highest SKU applicable to your request. That means if you
select fields in both the Essentials and the Pro SKUs, you are billed
based on the Pro SKU.
Using field masking is a good design practice to ensure that you don't request unnecessary data, which helps to avoid unnecessary processing time and billing charges.
About Autocomplete (New) sessions
An Autocomplete (New) session includes one or more Autocomplete (New) requests, and a Place Details (New) request or Address Validation request. The same session token is passed to the Autocomplete (New) request and to the subsequent Place Details (New) request or Address Validation request.
A session starts with the first Autocomplete (New) request. A Place Details (New) request or Address Validation request is then made when the user has selected one of the Autocomplete (New) suggestions. If a session is abandoned, meaning no Place Details (New) request or Address Validation request is made, Autocomplete (New) requests are charged as if no session token was provided.
After a user has selected a place (meaning a Place Details (New) request or Address Validation request is made), you must start a new session using a new session token.
A session token is good for one session and cannot be used for more than one session. If you reuse a session token, the session is considered invalid and the requests are charged as if no session token were provided.
