The session begins when the user starts typing a query, and concludes\nwhen they select a place and a call to Place Details (Legacy) is made. Each session can\nhave multiple autocomplete queries, followed by one place selection. The API\nkey(s) used for each request within a session must belong to the same\nGoogle Cloud console project. Once a session has concluded, the token is no longer\nvalid; your app must generate a fresh token for each session. If the\n`sessiontoken` parameter is omitted, or if you reuse a session\ntoken, the session is charged as if no session token was provided (each request\nis billed separately).\n\nWe recommend the following guidelines:\n\n- Use session tokens for all autocomplete sessions.\n- [Generate a fresh token](#create-session-tokens) for each session.\n- Ensure that the API key(s) used for all Place Autocomplete (Legacy) and Place Details (Legacy) requests within a session belong to the same Google Cloud console project.\n- Be sure to pass a unique session token for each new session. Using the same token for more than one session will result in each request being billed individually.\n\nYou can optionally omit the autocomplete session token from a request. If\nthe session token is omitted, each request is billed separately, triggering the\n\n[Autocomplete - Per Request](/maps/billing-and-pricing/sku-details#autocomplete-request-new-ess-sku)\n\n\nSKU. If you reuse a session token, the session is considered invalid and the\nrequests are charged as if no session token was provided.\n\nExample\n-------\n\nAs the user types a query, an autocomplete request is called every few\nkeystrokes (not per-character), and a list of possible results is returned.\nWhen the user makes a selection from the result list, the selection counts as\na request, and all of the requests made during the search are bundled and\ncounted as a single request. If the user selects a place, the search query is\navailable at no charge, and only the Place data request is charged. If the user does not make a\nselection within a few minutes of the beginning of the session, only the\nsearch query is charged.\n\nLet's examine this flow of events from the perspective of an app.\n\n1. A user begins typing a query to search for \"Paris, France\".\n2. Upon detecting user input, the app creates a new session token, \"Token A\".\n3. As the user types, the API makes an autocomplete request every few characters, displaying a new list of potential results for each: \n \"P\" \n \"Par\" \n \"Paris,\" \n \"Paris, Fr\" \n4. When the user makes a selection:\n - All requests resulting from the query are grouped and added to the session represented by \"Token A\", as a single request.\n - The user's selection is counted as a Place Detail request, and added to the session represented by \"Token A\".\n5. The session is concluded, and the app discards \"Token A\".\n\nFor more information about how Place Autocomplete (Legacy) requests are billed, see\n\n[Usage and Billing](/maps/documentation/places/android-sdk/usage-and-billing).\n\nCreate session tokens\n---------------------\n\n\nTo create a session token, call\n[`AutocompleteSessionToken.newInstance()`](/maps/documentation/places/android-sdk/reference/com/google/android/libraries/places/api/model/AutocompleteSessionToken#newInstance())."]]
