Connect your school's own Razorpay keys so parents can pay fees online.
Go to Settings → Schools → [your school] → Online payments.

Enter your school's own Razorpay key ID and secret so fees settle to your school's bank. They're encrypted before they're saved.
Each campus connects its own account, so money goes to the right bank per school.
Once connected, parents see a Pay button on their portal; captured payments record against the fee automatically.
