How It Works


Form Building

The first step involves building a web form with input fields for address components such as the first line, second line, city, state, and ZIP code. Each field is assigned a unique ID to facilitate the mapping of address data retrieved from the lookup service.

Initializing and Mapping Output Fields

The next step involves setting up the AddressLookup library with an API key for access, and configuring outputFields to map address data (e.g., first line, city, ZIP code) to corresponding form inputs by their IDs, ensuring automatic and accurate data population upon user selection.

User Interaction

Upon user input, AddressLookup generates address suggestions. Selection triggers automatic form population with details mapped via outputFields, ensuring accurate data entry.
