Does Data API split repayments of credit between interest and principal repayment?

If a user makes one payment to their credit card provider covering both interest and principle repayment, then only one transaction will be present on their bank statement, and therefore our Data API will only see one transaction and transaction amount (meaning not split out). However, if the user connects their credit card via the Data API, it’s possible to see some useful information such as:

credit limit
available balance
current balance
last statement balance
last statement date
payment due amount
payment due date

Not all these fields are available for all credit card providers. You can find out more about accounts and credit cards on our documentation.
