How the Address Autocomplete API works

Address Autocomplete is a very useful feature perfect for filling out web forms. It uses the autocomplete function as the user starts typing text into an input field, whether it is during the order process or in a registration or contact form.

Our API provides accurate and relevant address suggestions based on just a few keystrokes. It reduces the time it takes to enter an address, prevents typographical errors and reduces cart abandonment rates significantly. Data can be submitted faster and more accurately, speeding up transactions.

Why every checkout page needs Address Autocomplete

Have you ever abandoned a cart simply because filling out the form was too time-consuming?

One of the major challenges for eCommerce websites is to reject invalid addresses while speeding up customer checkouts. Nonexistent or wrong addresses cause additional costs and decrease customer satisfaction. By reducing typing errors and detecting incorrect addresses right at the point of entry, user experience and customer satisfaction are optimized and cart abandonment is minimized.

How to use the API

Integrating our Address Autocomplete API into your website or eCommerce platform is quick and easy. Ready-made plugins and example code in Javascript, PHP, Java etc. is available on our website. Once linked to your checkout page, the API automatically supports visitors with a list of suggestions.

Address Autocomplete is very flexible. You can for example customize it to only suggest addresses from certain countries.
