External services
This plugin connects to the zipcloud API to retrieve address information from Japanese postal codes. It is used to automatically fill in the address field when a user enters a postal code in the form.
The postal code entered by the user is sent to the zipcloud API only when the postal code field is used and the user inputs a value.
