What data can we get with PSD2?

PSD2 is all about payments and payment account data. Consequently, the type of information you can get is limited to payment accounts - checking accounts, current accounts and credit cards. Savings accounts, investment accounts or similar wouldn’t be shown. A general rule of thumb is - if you can make and receive payments from the mentioned accounts, you should be able to access this data via PSD2 APIs. 

A general overview of data points you can obtain via PSD2.

• Account details: holder name, a list of account holder's accounts and IBAN.
