## Overview {#overview}

#### Access your customers' financial data through a single, secure API {#access-your-customers-financial-data-through-a-single-secure-api}

Mastercard Open Finance Data enables you to access your users' financial data from thousands of banks and financial institutions. Built on Mastercard's global open finance platform, this API supports a unified integration model that simplifies access to account information, balances, transactions, and account holder details---without the need to integrate separately with each institution's interface.

Mastercard Open Finance Data is part of Mastercard's broader Open Finance ecosystem, designed to help partners build innovative financial services, improve decision-making, and deliver seamless user experiences.
Note: The Mastercard Open Finance Data product page can be found [here](https://developer.mastercard.com/open-finance-data/product/open-finance-data/index.md).

## How it works {#how-it-works}

By integrating to the Mastercard Open Finance Data API in your application, you can guide your users through the process of securely sharing their financial data and use this data to provide compelling, personalised services.

Mastercard's Flow provides a user experience to allow the user to consent to and authorise financial data sharing. This experience is configurable to allow you to provide certain screens in the journey.

The process begins within your application, where you prepare the user for data sharing and initiate the connection to Mastercard's Flow through the Open Finance Data API. The user is then guided through a secure consent experience, including authentication with their bank to authorize access.

Once consent is obtained, the system will collect the user financial data and make it available for your application to deliver personalised services. Clients receive updated account and transaction data at regular intervals without user interaction, provided the consent and access tokens remain valid, ensuring a seamless and continuous experience.
