Access by calling const {AutocompleteService} = await google.maps.importLibrary("places"). See Libraries in the Maps JavaScript API.
AutocompleteService
AutocompleteService()
Parameters:  None
Creates a new instance of the AutocompleteService.
getPlacePredictions
getPlacePredictions(request[, callback])

AutocompletionRequest interface

google.maps.places.AutocompletionRequest interface

An Autocompletion request to be sent to AutocompleteService.getPlacePredictions.
input
Type:  string
The user entered input string.
bounds 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
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.
location optional
Type:  LatLng optional
Location for prediction biasing. Predictions will be biased towards the given location and radius. Alternatively, bounds can be used.
locationBias optional
Type:  LocationBias optional
A soft boundary or hint to use when searching for places.
locationRestriction optional
Type:  LocationRestriction optional
Bounds to constrain search results.
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
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.

input
Type:  string

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.
