I token di sessione sono stringhe (o oggetti) generate dagli utenti che monitorano le chiamate di Autocomplete (New) come sessioni. Autocomplete (New) utilizza i token di sessione per raggruppare le fasi di query e selezione di una ricerca di completamento automatico dell'utente in una sessione discreta ai fini della fatturazione.
Gli utenti sono responsabili della creazione dei token di sessione per ogni sessione. I token
di sessione devono essere stringhe base64 sicure per URL e nomi file. Gli utenti possono generare token di sessione in qualsiasi modo, anche se Google consiglia di utilizzare identificatori univoci universali (UUID) versione 4 per i token di sessione.
La sessione inizia con una chiamata ad Autocomplete (New) e termina con una chiamata
a Place Details (New) o Address Validation. Ogni sessione può includere
più query Autocomplete (New), seguite da una richiesta a Place Details
(New) o Address Validation. Le chiavi API utilizzate per ogni richiesta all'interno di una
sessione devono appartenere allo stesso progetto Google Cloud Console.
I token di sessione terminano nei seguenti modi:
Viene chiamata Places Details (New).
Viene chiamato Address Validation.
La sessione è abbandonata.
Una volta terminata una sessione, il token non è più valido e la tua app deve
generare un nuovo token per ogni nuova sessione. Se il parametro sessionToken viene omesso o se riutilizzi un token di sessione, la nuova sessione viene addebitata come se non fosse stato fornito alcun token di sessione (ogni richiesta viene fatturata separatamente).

Autocomplete (New) uses session tokens to group the query\nand selection phases of a user autocomplete search into a discrete session for\nbilling purposes.\n\nUsers are responsible for creating session tokens for each session. Session\ntokens must be URL- and filename-safe base64 strings. Users can generate session\ntokens in any manner, although Google recommends using [version 4 universally\nunique identifiers (UUIDs)](https://tools.ietf.org/html/rfc4122) for session tokens.\n\nThe session begins with a call to Autocomplete (New), and concludes with a call\nto [Place Details (New)](/maps/documentation/places/android-sdk/details-place) or [Address Validation](/maps/documentation/address-validation/overview). Each session can have\nmultiple Autocomplete (New) queries, followed by one request to Place Details\n(New) or Address Validation. The API key(s) used for each request within a\nsession must belong to the same Google Cloud Console project.\n| **Note:** Session tokens cannot be exchanged between Places API (Legacy) endpoints and Places API (New) or Address Validation endpoints. For example, a [Place Autocomplete (Legacy)](/maps/documentation/places/android-sdk/autocomplete) request can be followed by a Place Details (Legacy) request in the same session, but it cannot be followed by a Place Details (New) request or an Address Validation request in the same session.\n\nSession tokens terminate in the following ways:\n\n- Place Details (New) is called.\n- Address Validation is called.\n- The session is abandoned.\n\n| **Note:** You can optionally omit the Autocomplete (New) session token from a request. If the session token is omitted, each request is billed separately and charges the [SKU: Autocomplete Requests](/maps/billing-and-pricing/sku-details#places_autocomplete-request-new-ess-sku).\n\nOnce a session has concluded, the token is no longer valid; your app must\ngenerate a fresh token for each new session. If the `sessionToken` parameter is\nomitted, or if you reuse a session token, the new session is charged as if no\nsession token was provided (each request is billed separately).\n\nFor more information about how Autocomplete (New) requests are billed, see\n[Autocomplete (New) and session pricing](/maps/documentation/places/android-sdk/session-pricing)."]]
