New Custom Data Types

For model class "OBExternalAccountIdentification4Code", we have introduced a custom data type for Account/SchemeName called "UK.Santander.SavingsRollNumber" to identify some Savings Accounts which do not have a numeric sort code account number format.

Examples of this type of Savings Account number would be: SAVINGR12345678 or SAVING123456789

NB. This only applied to our Account & Transactions API v3.1


We are happy to communicate we have introduced in our Santander|DEVELOPERS portal a set of new features for the Account Information and Payment Initiation Services and in addition the launch of the Confirmation of Funds API. This new release makes now available functionality under PSD2 Regulation through the UK’s Open Banking specifications:

  • eIDAS certificates authentication
  • All Corporate Customers payment accounts
  • All Cahoot customers payment accounts
  • Credit Card accounts for AISP Services
  • Savings Accounts for AISP Services
  • Chaps and International Payment Services are now live
  • Our new Confirmation of Funds API for CBPII subscription

In parallel, all our User Interfaces have been updated to include the latest Strong Customer Authentication (SCA) changes to match this security requirement in our other customer channels, with the exception of Logon SCA changes – which have been deferred under direction from the FCA to Q1 2020.


For access to our testing services, please go to our PSD2-RTS compliant Sandbox 

Please note that if you're new to Open Banking or if you're using a version of an API or the first time, you'll need to start with Sandbox access.
