The add-on will utilize an API that provides real-time validation of shipping addresses.

When the customer enters their shipping address in the checkout form, the add-on will automatically trigger the API to validate the address.

The API will return a response indicating whether the address is valid or not. If it is not valid, an error message will be displayed to the customer prompting them to correct the address.

The add-on will integrate directly with the address form element, so there will be no additional steps required for the customer to validate their address.

The add-on will also store the validated address information for future use, making it easier for the customer to enter their shipping address in the future.

The integration will be fully customizable, so the validation criteria and error messages can be tailored to meet the needs of your specific business.

The add-on will be compatible with all major shipping carriers and will support international addresses as well.

The integration will be fully secure, ensuring that all customer information is protected at all times.

By integrating this add-on into your CommerceLab shop, you can improve the accuracy and efficiency of your shipping processes, reduce the risk of delivery errors, and provide a better customer experience overall.
