Cashgram is a secure way to transfer money to your customers. Once you create a Cashgram for a user only that user with the provided phone number can use that Cashgram. Cashgram is also active only for a limited amount of time, you can control the expiry time of each Cashgram. Post expiry, no one will be able to view/redeem the Cashgram.
Once a Cashgram has been redeemed or expired, the customer will not be able to view it again.
