Payments API Update – C2C, Corporate Salary Payments, Bill Payments & UPI

The Instant Cash Payments API supports multiple payment use cases, including Consumer-to-Consumer (C2C), Corporate Salary Payments (B2C), Bill Payments, and UPI (Unified Payments Interface) transactions.

The latest update extends the supported payment capabilities to include UPI transactions for India, in addition to the existing C2C, Corporate Salary Payment, and Bill Payment flows.

Depending on the applicable service and transaction flow, developers should use the corresponding transaction initiation endpoint:

(V1) Transaction Creation Endpoint: Create a Transaction (C2C and UPI)
(V2) Transaction Initiation Endpoint: Initiate Transaction V2 (C2C, B2C and UPI)
(V3) Transaction Initiation Endpoint: Initiate Transaction V3 (C2C, B2C, Ventaja and UPI)

The applicable transaction initiation flow supports the specific payload and validation requirements associated with each payment service. All other endpoints remain unchanged and continue to function as per the existing integration.

The countries currently supported for Corporate Salary Payments via Instant Cash are India, Bangladesh, Nepal, and the Philippines.

Bill Payments are currently supported for the Philippines through Ventaja.

UPI payments are supported for India, enabling transactions to be processed using the applicable UPI details and requirements.

Developers should use the appropriate transaction initiation endpoint based on the required payment service, while continuing to use the existing endpoints for all other operations unless otherwise specified.
