Similar to other payment solutions, whatsapp uses UPI for sending and receiving money.
WhatsApp has been toying with the idea of adding a peer-to-peer payment service for its users in India. This makes sense for a company and it is saying that this function is available now.
Once your account is linked, you’ll be able to start sending money to other WhatsApp users by tapping the attachments icon in a conversation. Tapping on a transaction that you send or receive will show its status and which of your bank accounts was used, and after the initial setup process, you can go back to the Payments settings page to view your entire payment history.
WhatsApp uses India’s UPI system for managing payments, and supported banks include Axis Bank, State Bank Of India, Yes Bank, ICICI Bank, and plenty more.
Along with being limited to users in India, you’ll also need to ensure you’re signed up for the WhatsApp beta to start using this.
