When customers arrive at checkout and start entering the first few characters of their address, Google Autocomplete will instantly provide a list of potential matching addresses. Customers select an address and the rest of the fields will be automatically filled. This is especially useful for customers on mobile where checking out on a small screen can be a long exercise in typing, misspelling, and retyping.
To achieve this, We have to create Google API key and integrate it with bigcommerce.
Google Autocomplete is powered by Google Maps and requires a Google Maps API key. Follow the steps below to get your key and add it to the BigCommerce control panel:
1. Use Google’s instructions to generate your API key.
2. In your BigCommerce control panel, go to Settings › Checkout.
3. Check the box for Use Google Maps services to autocomplete shipping and billing addresses and enter your Google Maps API Key.
4.Save your changes.
