Are Open Banking APIs Safe?

By  |  0 Comments

Many questions arise when considering open banking APIs, including what security standards are required to protect sensitive personal identifiable information. Of course, the answer will vary from country to country, but it is worth exploring how open banking regulations can help protect consumer information. In addition to security standards, regulatory frameworks govern how providers can implement open banking. Understanding these guidelines is vital for consumers, and this article aims to answer these questions in an accessible and helpful manner.


Security standards protect sensitive personal identifiable information.

One of the main concerns surrounding open banking APIs is the security of customer financial data. According to a recent survey, 48% of consumers have a negative view of open banking and cybersecurity. This is not surprising, as it seems that danger is lurking around every corner. There is always the risk that malicious third-party apps could access sensitive personal information. Hacking and data breaches are other potential risks, but the most important concern is ensuring that security standards protect customers’ financial data.

One key factor in ensuring personal data safety when using Open Banking APIs is understanding how the API is built. It is critical to understand the API’s intended functionality. If it exposes sensitive data, a secure implementation can prevent it. Often, development documentation for APIs is outdated and inaccurate. Developers may fail to update documentation. This can impact security teams and limit reusability. In the open banking space, reusability is paramount.


Regulations vary from country to country.

Open banking regulations vary from country to country. Although European regulations are less stringent than the UK’s, they still have many technical and regulatory requirements. Therefore, it is difficult to gauge this policy’s overall effect, especially as bank-specific API behavior is not standardized. This is where TrueLayer comes in. This platform provides connectors to banks’ APIs. With these connectors, developers can use open banking APIs and connect their products to the data.

Regulations vary from country to country, but open banking regulations are generally encouraged by a legal mandate that requires banks to share certain information with third parties. In many jurisdictions, screen scraping is widely practiced, which is technically legal but gives customers no control over their data. In addition, the process does not establish a clear liability framework for data breaches or fraud. Although screen scraping is technically legal under EU regulations, it would be illegal for TPPs to access this information without a customer’s consent.


Best practices define how to implement

The Payment Services Directive (PSD2) defines the specifications for financial services and the best practices for processing data. This piece of regulation covers the topic of Open Banking in the UK. Open Banking is not yet fully operational in the UK, but it will come to fruition in the future. In the meantime, the Open Banking ecosystem offers an increasing number of third-party services. Financial institutions should implement the Positive Acknowledgement pattern to enable these services to capture rich data on consumers’ intentions.

Open Banking APIs have some benefits. First, users can choose not to share their personal information with a third party. The banks must ensure that the third-party service provider meets strict security measures. Also, they must inform consumers about the use of their data. This creates transparency and gives customers more control over their financial data. While Open Banking is the way to go, it has disadvantages, too. To understand the benefits of Open Banking, read the following guide.


Regulatory frameworks for open banking

Currently, the regulatory frameworks for open banking APIs vary across different jurisdictions. In Europe, for example, the Second Payment Services Directive (PSD2) has recognized two types of open banking APIs as regulated activities. These are account information services and payment initiation services. Account information services allow the provider to provide consolidated account information, while payment initiation services allow the customer to initiate a payment transaction between two different account providers.

While open banking APIs promise convenience and streamline costs for financial institutions, the emergence of these applications poses severe risks to consumers’ financial privacy and security. While these APIs allow third-party companies to clean up customer accounts, they also introduce new security risks. The threat of fraudulent third-party applications is a genuine concern today, especially as data becomes more interconnected. Therefore, regulatory frameworks for open banking APIs must take the risk of cyber-attacks into account.
