How it works

form.html
<form>
  <label for="line_1">Address</label>
  <input id="line_1" />
  <input id="city" />
  <input id="state" />
  <input id="zip" />
</form>
01

Build your form

Give each address field a unique id so lookup can map results into it.

02

Initialize & map fields

Call setup() with your API key and map each output field to a form input by id.

03

Users select an address

Suggestions appear as they type. On selection, every mapped field is populated automatically.
