Open banking providers are the foundation of this industry

As a concept, open banking has ignited a revolution in the financial industry, allowing users to finally take full advantage of their financial data. With the possibility of third party access to bank accounts, financial data that was until now exclusively managed by banks, can be used by third party providers to offer a new range of services.

Open banking is regulated in the European Union by the revised payments service directive (PSD2), and OBIE (Open Banking Implementation Entity) in the UK.

In case open banking is still a new concept for you, take advantage of our detailed explanation of what open banking is, and what use cases can be created with it.


What is an open banking provider?

Essentially, they act as a middleman in the banking industry, allowing users to have access to an interface designed to match their necessities and access their financial data efficiently.

All third party providers (TPPs) must be licensed and registered as digital service providers with the FCA (UK Financial Conduct Authority) in the UK and the respective designated entity in each EEA country.

What type of TPP there are, and what can they do?

There are two main types of TPPs:

  • Payment Initiation Services Provider (PISP)
  • Account Information Service Provider (AISP)

A PISP can initiate a payment service without needing to use a card or log into a personal or corporate bank account. However, the Strong Customer Authentication (SCA) still applies to ensure security. This means that for any action to be performed, user consent and identity verification must be guaranteed.

An AISP is a digital service provider that aggregates your financial information from all banking institutions and portrays it in one place. It has no access to consumers funds, however, all the transactional data is accessible. AISPs can be used for better financial management purposes or to ease loan application processes. Just as it happens with PISPs, users need to give consent before an AISP can move forward with the requested information gathering.

Open banking API providers

Before going into what an API provider is, it’s essential to understand what an API is, since it is a crucial piece of the puzzle that allowed open banking online to become a reality.

An API, or Application Programming Interface, is a set of definitions and protocols for building and integrating software applications. Essentially, they allow developers to make their applications’ data and features available to other developers.

To know more about how they work and how they can be used, you can visit our page dedicated to APIs.

What is an API provider?

Open banking API providers are all the companies that, in one way or another, provide third party access to bank accounts.

With a summarised approach to the definition, we can consider API providers both AISPs and PISPs, since they all provide APIs to facilitate their customers' access to open banking.


What are the basic security rules API providers need to follow?

All third party providers need to be regulated and licensed to be an active member of the open banking industry. Since the implementation of PSD2, payment services need to ensure compliance with a very specific set of regulations.

One of the main pillars of PSD2 regarding security and fraud reduction is the implementation of strong customer authentication, also known as SCA.

If you want to know more in detail about SCA, we have a dedicated page to this topic. Below you can find all the basics to understand how it works, and why it is important.

Strong Customer Authentication has two main goals: reduce fraud and make online payments more secure.

The application of SCA is done by using two-factor authentication (2FA), where customers need to provide two independent pieces of information to confirm their identity:

  • Something they own (e.g., smartphone)
  • Something they know (e.g., PIN code)
  • Something they are (e.g., fingerprint)

With this regulation, customers can be sure that no one will be able to impersonate them and their financial information will be secure.
