How to show the monthly payments of monzo flex?

Hi there, I have built an application to plan my budget. I can see my balance and assign it as my budget but to assign as expense, I want to be able to show my monthly flex card payments (beside the total amount of credit).
For example the money I have in my account is 300 GBP
Flex card total payment is 250 GBP but payment for this month is 120 GBP.

Is there an API to show this specifit 120 GBP so that I can assign to a variable in my app as expense? (sorry for my english).

I don’t believe there is an API (at least public API) that shows the breakdown of the flex monthly payment, this payment is fully dependent on the credit agreement for that specific transaction.

If I remember correctly, each of the purchases in flex show up as a different account with flex_ as part of the name, it would be worth listing out your accounts and seeing what this shows, it might help identify information you can use.
