AutocompletionRequest interface

google.maps.places.AutocompletionRequest interface

An Autocompletion request to be sent to AutocompleteService.getPlacePredictions.

Requires the &libraries=places URL parameter. See Libraries in the Maps JavaScript API.

Properties
input	Type:  string The user entered input string.
bounds optional	Type:  LatLngBounds|LatLngBoundsLiteral optional Bounds for prediction biasing. Predictions will be biased towards, but not restricted to, the given bounds. Both location and radius will be ignored if bounds is set.
componentRestrictions optional	Type:  ComponentRestrictions optional The component restrictions. Component restrictions are used to restrict predictions to only those within the parent component. For example, the country.
language optional	Notice: Available only in the v=beta channel. Type:  string optional A language identifier for the language in which the results should be returned, if possible. Results in the selected language may be given a higher ranking, but suggestions are not restricted to this language. See the list of supported languages. Google often updates the supported languages, so this list may not be exhaustive.
location optional	Type:  LatLng optional Location for prediction biasing. Predictions will be biased towards the given location and radius. Alternatively, bounds can be used.
offset optional	Type:  number optional The character position in the input term at which the service uses text for predictions (the position of the cursor in the input field).
origin optional	Type:  LatLng|LatLngLiteral optional The location where AutocompletePrediction.distance_meters is calculated from.
radius optional	Type:  number optional The radius of the area used for prediction biasing. The radius is specified in meters, and must always be accompanied by a location property. Alternatively, bounds can be used.
region optional	Notice: Available only in the v=beta channel. Type:  string optional A region code which is used for result formatting and for result filtering. It does not restrict the suggestions to this country. The region code accepts a ccTLD ("top-level domain") two-character value. Most ccTLD codes are identical to ISO 3166-1 codes, with some notable exceptions. For example, the United Kingdom's ccTLD is "uk" (.co.uk) while its ISO 3166-1 code is "gb" (technically for the entity of "The United Kingdom of Great Britain and Northern Ireland").
sessionToken optional	Type:  AutocompleteSessionToken optional Unique reference used to bundle individual requests into sessions.
types optional	Type:  Array<string> optional The types of predictions to be returned. For supported types, see the developer's guide. If no types are specified, all types will be returned.

AutocompleteResponse class

bounds optional	Type:  LatLngBounds|LatLngBoundsLiteral optional Bounds for prediction biasing. Predictions will be biased towards, but not restricted to, the given bounds. Both location and radius will be ignored if bounds is set.
location optional	Type:  LatLng optional Location for prediction biasing. Predictions will be biased towards the given location and radius. Alternatively, bounds can be used.
offset optional	Type:  number optional The character position in the input term at which the service uses text for predictions (the position of the cursor in the input field).
radius optional	Type:  number optional The radius of the area used for prediction biasing. The radius is specified in meters, and must always be accompanied by a location property. Alternatively, bounds can be used.

AutocompleteSessionToken class
