How to Use Google Places Autocomplete API

When users select a place from a list, Places Autocomplete returns details for that location. This information can be used to display address and geocoding information. The service can be programmed to optimize results and return only the fields required.

To use Google Places Autocomplete, you must create a session token. This is used to charge for each request. In most cases, it is a better choice to pay for each request rather than using a single session token for all requests.

Places Autocomplete uses HTTP requests to determine a user's input and predict an address. Each place has a unique Place ID. It's possible to set a radius to improve the quality of predictions. If you don't want to specify a radius, you can pass a location parameter.

As part of the Places API, Places Autocomplete also allows you to restrict the results to a particular type or region. For example, you can search for restaurants only in the United States. You can also get the address of a selected place through the Geocoding API.

In addition to displaying autocomplete suggestions, a predefined place object can also include the description of the place. It can be useful for websites that allow visitors to select a place before showing the address.

Places Autocomplete support is incomplete for some countries. Examples of these are Czechia, Estonia, Lithuania, and Lithuania.

Places Autocomplete requires a valid API key and a unique session token. These keys are provided by Google. They can be used by any website or application.
