What is an Open Banking platform?

At a glance:

  • Open Banking platforms provide a multi-bank layer for accessing data and initiating payments
  • Open Banking APIs are the technical interface, while an Open Banking platform is the full operating system
  • Businesses use these platforms for payments, lending, reconciliation, and more
  • They must be built within the PSD2 regulation framework across Europe
  • When looking for a vendor, key aspects to evaluate include bank coverage and compliance

An Open Banking platform gives businesses a scalable and secure way to connect to multiple financial institutions, allowing them to aggregate checking account data in one place and initiate direct bank payments (A2A).

Instead of maintaining fragmented integrations and having to obtain the respective mandatory licenses, teams can rely on a single solution to launch faster, reduce technical overheads, improve risk workflows and fraud prevention, and streamline payments.

This enables use cases like account aggregation for personalized financial management, quicker, more accurate lending decisions, and automated fund transfer reconciliation.

What does Open Banking mean?

Open Banking is a regulated framework that lets individuals and businesses securely share payment account data and initiate transactions through licensed third-party vendors, with explicit user consent. 

Regulators have been working for decades to improve financial data sharing. Since the launch of the first Payment Services Directive (PSD1) in 2007, regulators have focused more and more on the power customers hold over their own information. First coined within UK regulations, Open Banking is a concept that aims to foster competition between banks and increase consumer control over their financial data.

Open Banking relies on standardized APIs (Application Programming Interfaces), a connection linking computers or software, that ensure secure communication between banks and authorized providers. In practice, this makes it possible to access data such as account balances and transaction history for use cases including account aggregation, affordability checks, fraud prevention, and reconciliation. It also enables payment initiation, with strong customer authentication applied where required.

PSD2, the legal framework governing Open Banking behind the scenes

In Europe, the Payment Services Directive (PSD2) laid the legal foundations for Open Banking. It became applicable in January 2018, requiring banks to give licensed third-party providers access to payment account data, with the user’s consent, while creating a regulated basis for new payment services to emerge.

Its broader goal was to make electronic payments safer, increase competition, and support a more integrated EU payments market. Looking ahead, the framework is being updated through PSD3 and the proposed Payment Services Regulation (PSR), which are intended to strengthen consumer protection, reduce fraud, and make implementation more consistent across the EU.

What is an Open Banking platform?

An Open Banking platform provides secure technology for accessing checking account data and initiating bank payments through APIs. These platforms, such as Powens, connect to multiple banks so users can safely share their banking information with third-party payment service providers (PSPs). The PSPs use Open Banking platforms to access capabilities like:

  • Financial account aggregation across multiple banks
  • Secure user consent management
  • Direct bank payments (A2A)
  • Transaction monitoring and financial insights
  • Personalized financial management tools
  • Enhanced fraud prevention and risk monitoring
  • Operational and support tooling for businesses

Open Banking platforms help businesses build and scale financial products without creating separate integrations for every bank. Instead, they provide a unified layer for accessing account information services (AIS) and payment initiation services (PIS) under PSD2 regulations in Europe.

Open Banking platform vs. Open Banking API

The term Open Banking API can refer to two things: the mandatory, “raw” APIs built by a bank to share data and initiate payments, or the “unified” API offered by a service provider. While banks provide the initial entry point, an Open Banking platform acts as a hub that connects to thousands of these individual bank APIs and translates them into a single, standardized connection.

Most businesses choose a platform for this very reason because it handles complex technical maintenance and provides the necessary AISP/PISP regulatory licenses. This allows companies to access the entire banking ecosystem through one provider-side API without the massive cost of building and regulating their own infrastructure.

Open Banking platform vs. Open Finance platform

Open Banking platforms focus on PSD2-regulated bank data and payments (AIS/PIS), connecting current accounts via standardized APIs. 

Taking this one step further, Open Finance platforms extend the scope to broader financial data (such as investments, insurance, and pensions) to create a more comprehensive ecosystem. It’s important to note that these platforms (and Open Finance as a whole) are far less regulated than Open Banking solutions. Moreover, due to a lack of mandatory and standardized APIs, many Open Finance platforms thus use scraping technology to access and provide this type of data instead.

Why businesses use Open Banking platforms

Firms leverage established, compliant Open Banking platforms to build and roll out financial products faster and more cost-effectively. The technology can eliminate fragmented bank integrations and streamline connectivity to financial institutions to achieve benefits like:

  • Faster time-to-market
  • Less engineering complexity
  • Better coverage across banks
  • Better connection/conversion performance
  • More reliable data for product and risk decisions
  • Lower operational burden than building direct connections

Implementing an Open Banking platform gives your business a unified interface to access and manage high-quality financial data, while unlocking new revenue opportunities along the way. 

What can you build with an Open Banking platform?

How does an Open Banking platform work?

The actors

Three key players are connected through an Open Banking platform:

  1. The Account Servicing Payment Service Provider (ASPSP): Typically a bank or other financial institution that manages the customer’s financial account.
  2. The third-party provider: Can be fintechs or other businesses that deliver financial services and solutions to customers.
  3. The customer: An individual or company who grants their consent for third parties to access financial data and initiate payment directly from their bank account. 

The flow

  1. The user provides their consent.
  2. Authentication is performed at the bank level, including Strong Customer Authentication (SCA). 
  3. With consent and authentication confirmed, third parties can either access account data for up to 180 days, after which consent must be renewed, or initiate a payment, depending on what the user has authorized.
  4. For AIS, the retrieved data is then normalized and enriched, while for PIS, the platform transmits the transaction order so it can be executed by the bank.
  5. Finally, the data is delivered into the client product.

What the platform adds

Platforms offer ‌unified integration across banks, reducing technical overhead. They add:

  • Monitoring capabilities
  • Retry logic and incident handling
  • Improved UX around SCA and consent processes
  • Higher conversion rates through the simplification of compliance

Is Open Banking secure?

Under PSD2, Open Banking services in Europe must operate within a secure, compliant, and permission-based framework. Access to financial data or payment initiation can only be granted with the user’s explicit consent, ensuring full control over what is shared and with whom.

Additionally, Strong Customer Authentication (SCA) is required for most interactions, adding an extra layer of protection through multi-factor verification.

For multi-factor SCA, a user must provide two of the three following elements:

  1. Something they know (knowledge, like a password)
  2. Something they own (devices associated with their identity, such as a smartphone)
  3. Something they are (biometrics, like a fingerprint or face scan)

However, the level of trust and security can depend on the quality of the provider and how the solution is implemented. Businesses should evaluate platforms based on their compliance posture and overall security architecture. Critical security considerations when choosing a vendor include: 

  • Auditability of data access
  • Clear and thorough documentation
  • Incident handling processes
  • Strong technical security controls
