Places API supports the existing Autocomplete and Query Autocomplete APIs. If you are familiar with these APIs, Autocomplete (New) makes the following changes:
- Autocomplete (New) uses HTTP POST requests. Pass parameters in the request body or in headers as part of an HTTP POST request. In contrast, with the existing APIs, you pass URL parameters using an HTTP GET request.
- Autocomplete (New) supports both API keys and OAuth tokens as the authentication mechanism.
- Only JSON is supported as a response format in Autocomplete (New).
The following table lists parameters in the existing Autocomplete and Query Autocomplete APIs that have been renamed or modified for Autocomplete (New), or parameters that are no longer supported.

Example request
The following example GET request uses the existing
Place Autocomplete. In this example, you request a JSON
response containing information about places called "Amoeba" that are of type
establishment
and pass all parameters as URL parameters:
curl -L -X GET 'https://maps.googleapis.com/maps/api/place/autocomplete/json?input=amoeba&types=establishment&location=37.76999%2C-122.44696&radius=500&key=YOUR_API_KEY'
With Autocomplete (New), you make a POST request and pass all parameters in the JSON request body or in headers as part of the POST request. This example also uses a field mask so the response only includes the display name and formatted address of the place:
curl -X POST -d '{ "input": "Amoeba", "locationBias": { "circle": { "center": { "latitude": 37.76999, "longitude": -122.44696 }, "radius": 500.0 } } }' \ -H 'Content-Type: application/json' -H "X-Goog-Api-Key: API_KEY" \ https://places.googleapis.com/v1/places:autocomplete
