What is Open Banking Platform?

Open source mobile banking platform is a transformative practice that redefines the payment landscape by granting authorized third-party providers (TPPs) access to a customer's banking data through secure application programming interfaces (APIs). This access is only permitted with explicit consent from the customer, giving them full control over their data-sharing preferences.

The mechanics of open banking involve TPPs acting on behalf of bank customers to offer two primary services:

  • Account Information Services (AIS): This service enables customers to access and consolidate information such as account balances and transaction history from all their bank accounts in one centralized platform.
  • Payment Initiation Services (PIS): With PIS, customers can make online payments seamlessly without the need to manually input credit card details. Instead, they authorize secure payment transactions directly from their bank accounts.

For a clearer understanding, let's consider a money manager app as an example. In a non-open banking scenario, users must individually interact with each of their banks, logging in and manually transferring relevant data to the app. This process can be time-consuming.

With open banking app, the user experience is simplified. Customers grant the TPP permission to access their banking data, and the TPP then uses open banking APIs to retrieve information from all the user's accounts, consolidating it into a single, accessible interface. As a result, users can effortlessly view their transaction history, account balances, and spending with just a few clicks.

Open banking apps also revolutionize payment procedures. When merchants collaborate with PIS providers, customers can make online payments with ease. Instead of entering personal card details, users simply click on a payment link or scan a QR code on the merchant's website. They are then redirected to their bank app to confirm the payment, without exposing their sensitive bank information to the merchant.

Overall, open banking empowers customers with greater convenience, enhanced security, and control over their financial data, making it a game-changer in the payment landscape.

How Do Open Banking APIs Work?

Open banking APIs (Application Programming Interfaces) play a crucial role in facilitating secure access to customer data and transaction initiation by third-party providers. Let's delve into how open banking APIs work:

Customer Authorization

Before a third-party provider can access a customer's data, explicit consent from the customer is required. The third-party provider's application redirects the customer to the bank's authorization page, where the customer logs in to their bank account and grants permission for the third-party provider to access their data.

Data Sharing

Once the customer provides consent, the bank shares the customer's data with the third-party provider using an API. This API enables the secure and standardized retrieval of specific data, such as transaction history and account balance, from the customer's bank account.

Transaction Initiation

In addition to data access, open banking APIs allow third-party providers to initiate transactions. For instance, a third-party provider can utilize the API to directly initiate a payment from the customer's bank account without requiring the customer to log in to their online banking.


Open banking APIs employ robust security measures to safeguard customer data. These measures include encryption, two-factor authentication, and access controls that limit the data accessible to third-party providers, ensuring the protection of sensitive information.

Open banking APIs establish a secure and standardized pathway for third-party providers to access customer data and initiate transactions. This fosters increased competition and innovation within the banking industry while empowering customers with better control over their data and services.
