Webform Auto Address

Autocompleting addresses is one of the small steps to create a better web experience. The API of postcode.nl offers autocompletion functionality for addresses located in The Netherlands. This module integrates this service into Webform by creating a component that automatically fills in the street name and city when the user provides his/her postal code and house number. The service that responds the address information is offered free of charge to webshops by postcode.nl.

The module's functionality is designed to assists users/visitors. Therefore, no validation is applied, allowing the user/visitor to enter a non-existing address (i.e., addresses postcode.nl isn't aware of). This also means that when no (valid) key and secret are available for the postcode.nl API, this module is still functional!

Results of lookups using the postcode.nl API are cached for 15 minutes to prevent making unnecessary requests (even lookups that didn't respond a correct lookup result).
