Verify bank funding source for master account

I am trying to add bank account for master account using this Create a funding source for an account Documentation. Now I would like to know all the other options which can be used to verify this unverified funding source in master account i.e., if I can use plaid or any other flow so I do not have to rely on micro-deposits.
I have already tried micro deposits flow to verify bank account in sandbox but there is no proper flow mentioned in docs so I am confused on how it exactly works so can you also please shed some light on that too?

Hi @Saurav – while in Sandbox you will need to verify any additional Master Account banks using microdeposits, in Production we do provide an Instant Bank Account verification option in the Dashboard! You will not need to build out this flow on your end.

Let me know if you have any questions!
