# Overview

> Learn how to configure Link parameters and callbacks.

Argyle Link is a front-end UI element that allows users to grant your application access to their payroll accounts. It can be integrated natively on iOS, Android, ReactNative, and JavaScript and can be displayed on any part of your application.

To configure Argyle Link:

* Follow the steps of our [integration guides](/legacy/guides/argyle-link/embed/web).
* Adjust [Link's Configuration parameters](/legacy/api-reference/configuration-parameters).
* [Customize](/legacy/guides/argyle-link/customize) Link's user interface elements [in Console](https://console.argyle.com/flows).
* Configure [Callbacks](/legacy/api-reference/callbacks).

Within the Argyle API, the employers or payroll providers which hold a user's payroll account are referred to as [Link items](/legacy/api-reference/link-items).

The information entered into Argyle Link by users is encrypted and Argyle securely handles the complexity of multi-factor authentication and access control, which provides a smooth user experience for your users.
