API information for Third Party Providers

As mandated by the Second Payment Services Directive (PSD2), we have developed a suite of Application Programming Interfaces (APIs) to allow Regulated Third Party Providers (TPPs) to securely connect with us.

If you are a Third Party Provider regulated and authorised by your in-country regulator as an Account Information Service Provider or Payment Initiation Service Provider for the purposes of PSD2, you can use the following link to access our API Portal where you will find all of the information required for your development. Within the API Portal, please select the United Kingdom as the market for PSD2 related APIs. Please feel free to use the “Support” tab within the API Portal if you have any queries or questions as a Third Party Provider.
