## <span style="color:#7b2cbf">How It Works</span>  
        
<Steps>
  <Step title="Create an Order">
    Use the **Create Order API** to initiate a payment. The response will include an `orderId`.
  </Step>
  <Step title="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`.
  </Step>
  <Step title="Redirect for Bank Authentication">
    Redirect the user to the redirectionUrl to complete the authentication process.
  </Step>
    <Step title="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.
  </Step>
    <Step title="Redirect to Return URL">
    The user is redirected to the returnUrl provided during order creation or onboarding.
  </Step>
    <Step title="Verify Transaction Status">
    Use the Get Transaction Status API to confirm the transaction outcome.
  </Step>
    <Step title="Process Refunds">
    Use the Refund API to initiate full or partial refunds as needed.
