Initiate a Payment [v3]

POST 
/api/v3/initiate-payment

Initiate a payment for an order after the customer has selected their payment mode and provided the required details. The response guides the subsequent payment flow — redirect for cards/netbanking, OTP for pay later, or QR for UPI.

Card PAN must be encrypted

For card payments, card details (card_no, cvv, expiry, card_holder_name) must be RSA-encrypted before submission. Raw card PAN data is not accepted.

Quick Reference

• Required: order_id, payment_mode_code, card_input_type
• Conditional: card details (card mode), upi_id (UPI), bank_code (netbanking), wallet_code (wallets), payment_flow (intent/collect/qr)
• Returns: transaction_id, payment_status, and next actions (redirect, complete_payment, show_qr, launch_upi_app, etc.)
