Data transfer from Gmail to FinMap

We need to ensure that all transactions (income and expenses) from the personal account of Privat24 are sent to FinMap.
The FinMap service does not have the capability to integrate with PrivatBank for individuals (only with Privat24 for businesses). However, in Privat24, it is possible to set up notifications about transactions to an email.
There can be several cards in Privat24, and it is necessary to set up a filter by which a particular transaction will relate to the corresponding account. It is also necessary to identify whether it is an expense or income, and to transmit the purpose, time, and date. There are 6 PrivatBank accounts, and there will be 8. Accordingly, this system must have the capability to scale.
