Step 2: Payment process url for checkout 🔗
Once your order is created successfully,then you will get payment process url and UPI link in response. This payment url is used to redirect to actual payment screen.
Developer can redirect to payment process url using webview. Based on finish method inside webview we can compare with the redirect url to navigate back.
UPI Link is for UPI payment. You can use either payment process URL or UPI based on your requirement.
Step 3: Order Details (API request Parameters) 🔗
You can get order details by passing the below request parameters.
