How Does Our Address Autocomplete API Work?

AU Addresses
  • Generate Key
    Create a Public API Key in the Developers section of your dashboard and whitelist your website’s domain for secure access.
  • Embed Script
    Include the PostGrid autocomplete script in your HTML and initialise it by setting the data-pg-key attribute with your public key.
  • Map Fields
    Attach data attributes such as data-pg-address-line1 and data-pg-postal-or-zip to your input fields to enable automatic data population.
  • Filter Results
    Utilise the data-pg-country-filter attribute to restrict autocomplete suggestions to specific countries like ‘AU’ or ‘US’ as defined in the API.
  • Finalise Verification
    Configure your form to trigger a final verification call upon selection to ensure the address is AMAS-certified and deliverable.
