Prepare to be inspired by the limitless opportunities of open banking!

What Does Open Banking Platform mean?

The open-source mobile banking platform represents a revolutionary approach that reshapes the payment landscape, allowing authorized third-party providers (TPPs) to access a customer’s banking data via secure application programming interfaces (APIs). This access is exclusively granted with explicit consent from the customer, empowering them with complete control over their data-sharing preferences.

The operational aspects of open banking entail TPPs acting as intermediaries for bank customers to provide two core services:

  • Account Information Services (AIS): This service allows customers to conveniently access and consolidate information, including account balances and transaction history, from all of their bank accounts within a single centralized platform.
  • Payment Initiation Services (PIS): PIS streamlines the online payment process for customers, eliminating the need for manual entry of credit card details. Instead, customers can securely authorize 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, consumers must individually interact with each of their banks, logging in & manually transferring relevant data to the application. This process can be time-consuming.

Open banking apps streamline the user experience. Customers provide the TPP with permission to access their banking data, and the TPP utilizes open banking APIs to fetch information from all the user’s accounts, aggregating it within a single, user-friendly interface. Consequently, users can effortlessly access their transaction history, account balances, and spending details with just a few clicks.

Open banking apps also transform payment processes. Through collaborations with PIS providers, customers can effortlessly make online payments. Instead of manually entering personal card details, users can 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, all without divulging their sensitive bank information to the merchant.

In the realm of payment solutions, open banking is a transformative force, providing customers with heightened convenience, fortified security, and unprecedented control over their financial information.

Existing Solutions in the Market & Key Trends

The open banking sector has experienced swift expansion, with several established solutions gaining favor among both consumers and businesses. Here are a few notable examples of offerings within the open banking market:

  • Payment Initiation Services: This solution empowers consumers to execute direct payments to merchants from their bank accounts, eliminating the necessity for card-based transactions.
  • Account Aggregation Services: These services grant consumers the ability to access and oversee all their financial accounts, irrespective of the financial institution, through a unified platform. This streamlines financial management and offers a comprehensive perspective on one’s financial status.
  • Personal Financial Management (PFM) Tools: Personal finance management (PFM) tools provide tailored insights into an individual’s spending habits and overall financial well-being. They offer suggestions on saving money, decreasing debt, and enhancing financial planning.
  • Lending Platforms: Leveraging open banking data, lending platforms provide access to a diverse range of lending products with competitive rates & terms for both customers & businesses.

Although the open banking industry is in its initial phases, it is progressing swiftly and poised to usher in profound transformations within the financial services sector in the foreseeable future. As open banking garners broader acceptance, we foresee the emergence of pioneering solutions and services that will revolutionize the ease, convenience, and security of financial management as never before. With both consumers and businesses embracing the potential of open banking, the financial landscape is on the brink of experiencing substantial growth and remarkable enhancements in inefficient financial management.

How Do Open Banking APIs Work?

Open banking Application Programming Interfaces (APIs) have a pivotal role in ensuring secure access to customer data and enabling third-party providers to initiate transactions. Let’s explore the inner workings of open banking APIs:

Client Authorization

Before a third-party provider can access a client’s data, explicit consent is required. The third-party provider’s app redirects the client to the bank’s authorization page, where the client logs in to their bank account & grants permission for the third-party provider to access their data.

Data Sharing

Once the client consents, the bank shares the client’s data with the third-party provider utilizing an API. This API allows the secure & standardized retrieval of specific data, such as transaction history & account balance, from the client’s bank account.

Transaction Initiation

Beyond data access, open banking APIs empower third-party providers to initiate transactions as well. For example, a third-party provider can use the API to directly initiate a payment from the client’s bank account without needing the client to log in to their online banking.


Open banking APIs incorporate robust security protocols to protect customer data. These safeguards encompass encryption, two-factor authentication, and access controls that restrict the data accessible to third-party providers, guaranteeing the security of sensitive information.

Open banking APIs create a secure and standardized conduit for third-party providers to access customer data and trigger transactions. This not only encourages heightened competition and innovation within the banking sector but also empowers customers by granting them improved control over their data and services.
