Create Connections via Rest-API

I am developing a finance app (for personal use at the moment). I used to access all the PSD2 provided data (accounts, transactions, etc.) by GoCardless directly but this is not possible anymore. I integrated a bank browser in my app where the user can select a bank out of all available banks, enter credentials, approve mfa and select the actual accounts the user has at a certain bank.

What I would like to have is:

1. An Endpoint where I can request all available Banks (like in creating a new Connection in Dashboard). In best case with query parameters for EU or even city, so I don’t have to download everything.

2. An Endpoint where I can create a Connection for a selected Bank programatically.

3. A Link for approve (maybe as result of Connection creation?).

4. An Endpoint to check if approval is done.

This would be really nice but I can work without it, so I just want to share my thoughts :)
