# Addresses

## Overview

The **Limio Address Form** Lightning Web Component (`flowAddress`) is designed for use in Salesforce Flows, offering a configurable interface for address input. A key feature is the **Input: Mandatory fields** property, which defines which fields must be completed for validation.

## Property Configuration

* **API Name:** `requiredFields`
* **Type:** `String` (comma-separated, case-sensitive)
* **Label:** Input: Mandatory fields
* **Allowed values:** `country`, `postalCode`, `province`, `city`, `street`
* **Example:** `country,postalCode,city`

Enter field names as a comma-separated list to specify which fields are required. These are case-sensitive and must not include spaces.

## Behavior & Validation

### Field Enforcement

The component:

* Parses `requiredFields` into an internal array.
* Validates that all specified fields are completed.
* Displays error messages listing any missing values.
* Blocks navigation to the next screen in the Flow if validation fails.

### Region-Specific Logic

If the country is set to `US` or `CA`, the component **automatically adds** `country`, `postalCode`, and `province` to the required list—ensuring compliance with regional standards.

### Dynamic Updates

The required fields list updates in real time when the country value changes to `US` or `CA`.

## Best Practices

* ✅ Use only valid field names: `country`, `postalCode`, `province`, `city`, `street`.
* 🧠 Field names are **case-sensitive**.
* 🚫 Do not include spaces between field names.

## Summary

The `requiredFields` property in the Limio Address Form LWC enables Flow admins to enforce address data requirements. It provides flexible validation logic and automatically handles country-specific requirements for the US and Canada.
