Key Features#

End-to-end payment processing
Refund and dispute management
Tokenization for secure card storage
Real-time transaction updates via webhooks

Ideal Use Cases#

Custom-built web or mobile applications
Platforms needing granular control over payment steps

How It Works#

1
Create an Order
Use the Create Order API to initiate a payment. The response will include an orderId.
2
Initiate Payment Based on Mode
UPI Payments: Use the UPI Intent Links API to fetch intent links or the QR Code API to generate a QR code.
Cards / Netbanking / UPI Collect: Submit the user’s payment details via the Submit Payment Detail API.
The API response will return a redirectionUrl and transactionId.
3
Redirect for Bank Authentication
Redirect the user to the redirectionUrl to complete the authentication process.
4
Receive Server-to-Server Notification
After transaction processing, Olympus sends a webhook notification to the notifyUrl specified in the Create Order API or configured during onboarding.
5
Redirect to Return URL
The user is redirected to the returnUrl provided during order creation or onboarding.
6
Verify Transaction Status
Use the Get Transaction Status API to confirm the transaction outcome.
7
Process Refunds
Use the Refund API to initiate full or partial refunds as needed.
