LoadingHow Does Our Address Autocomplete API Work?
- Generate Key
Create a Public API Key in the Developers section of the dashboard and whitelist your website's domain for secure access. - Embed Script
Include the PostGrid autocomplete script in your HTML and initialize it by setting the data-pg-key attribute with the public key. - Map Fields
Attach data attributes such as data-pg-address-line1 and data-pg-postal-or-zip to input fields to enable automatic data population. - Filter Results
Utilize the data-pg-country-filter attribute to restrict autocomplete suggestions to specific countries like ‘US' or ‘CA' as defined in the API. - Final Verification
Configure your form to trigger a final verification call upon selection to ensure the address is CASS/SERP certified and deliverable.
