BEFORE YOU START

A few things to know.

Who enters the Gmail and UPI details?

Each merchant enters their own Gmail address, dedicated Google app password and receiving UPI ID after registration and approval. Never share these credentials in chat.

Is every payment confirmed automatically?

Automatic matching requires an authenticated receipt containing the exact order reference, amount and payment time. If the email lacks the order reference, the receipt needs merchant review. A payment note is not guaranteed to appear in a FamApp email.

Where does the customer’s money go?

The customer pays the merchant’s configured UPI ID directly. STORM PAY records and reconciles payments; it does not collect, hold or refund those funds.

Is STORM PAY an official FamPay product?

No. STORM PAY is an independent merchant application. FamApp and FamPay names belong to their respective owners.
