# Overview

> Account Center is UQPAY's shared platform layer for authentication, account management, and webhook configuration.

Account Center is the unified platform layer that underpins all UQPAY products. It handles three core responsibilities that every product depends on: issuing access tokens for API authentication, managing master and subaccount structures, and configuring webhook endpoints to receive event notifications.

## Account structure

Account Center uses a master account and subaccount model. Your master account holds a single set of API credentials that apply across all subaccounts. Each subaccount can represent a merchant, subsidiary, or end customer depending on your use case.

See [Connected Accounts](/account-center/v1.6/guide/connected-accounts) for details on how to create and manage subaccounts.

## Products

Account Center authentication and account management apply to all UQPAY products.
