The three main routes to open banking integration

Open banking initiatives have revolutionised the financial services landscape, enabling companies to innovate in areas like payment methods, personal finance management, and customer identification. In this article, we'll explore some of the main approaches that businesses can take to leverage the benefits of open banking.

However, before we dive straight into it, open banking can be a complex field with its own set of terms and acronyms. To help you navigate this world, here's a concise glossary of essential terms:

  • Open Banking: This refers to the practice of giving third parties permission-based access to consumers' bank account data.
  • PISPs (Payment Information Service Providers): These are businesses authorised to provide open banking-based payment services.
  • AISPs (Account Information Service Providers): These are businesses authorised to provide open banking-based account information services.
  • TPPs (Third Party Providers): These are businesses holding an AISP or PSIP license.
  • APIs (Application Programming Interfaces): These are programming interfaces used by developers to connect different software applications.
  • API Aggregator: These are businesses that enable other organisations to access the banks' APIs through their own interface.
  • FCA (Financial Conduct Authority): This is the UK's financial regulatory body with a focus on conduct.
  • API Endpoints: These are touchpoints where an API sends information when communicating with another system.

For organisations looking for open banking solutions, there are three typical approaches when it comes open banking integration:

1. Building connections and getting regulated

Creating your own integration is a significant effort and is most suitable for businesses planning to build products or services entirely based on open banking. However, even in this scenario, working with an API aggregator may offer advantages.

For businesses choosing this path, becoming regulated as an open banking provider and developing API connections with each bank is necessary.

Costs, benefits & considerations

The regulatory process involves assigning compliance teams or hiring legal assistance, along with developers for API integration. Ongoing efforts are also required to maintain these API connections.

User experience is crucial, and investment in creating an intuitive interface is essential. Building an integration is resource-intensive, but it provides complete control over open banking technology.

2. Working with an API aggregator 

API aggregators provide businesses access to multiple bank APIs through a single interface. This approach streamlines the process compared to manual integration with each bank.

Working with an aggregator allows you to start with open banking more quickly than building your integration. However, product development is still necessary since API aggregators are not "plug and play" services.

Depending on the regulatory status of the API aggregator and your specific use case, you may need to be regulated as a PISP or AISP. Not all aggregators are regulated, but it's crucial to clarify this early in the process.

Choosing an aggregator: costs, benefits and considerations

Aggregator services typically involve volume-based pricing and may include integration fees. While it's cost-effective compared to building your integration, it still requires some development effort.

3. Using an end-to-end solution

End-to-end solutions allow you to harness open banking without extensive development work. These solutions are designed to be readily integrated and used by organisations.

An ideal end-to-end solution should offer a user-friendly experience and an intuitive interface. While it may not cover all niche use cases, it's suitable for common ones.

Costs, benefits and considerations

Cost estimation for an end-to-end solution is straightforward. You pay for the product or service, with pricing models varying. Integration may also involve fees.

The time to market is short, as there's no need for in-depth technology development. Consider factors like supported countries and banks, onboarding ease, data security measures, and the end-user experience when evaluating a service.

Summary: choosing a provider

Once you've defined your open banking goals, it's time to select the approach that suits your needs:

  • Building your integration for complete control.
  • Working with an API aggregator for a quicker start.
  • Leveraging customer-ready services for rapid market entry.
