​

Overview

• Process payments securely through Razorpay’s infrastructure
• Automatically sync customers and invoices
• Handle complex usage-based billing scenarios
• Receive real-time updates via webhooks

​

System Architecture

​

Division of Responsibilities

• Usage-based charge calculation and metering
• Complex billing logic and usage invoice generation
• Plan configuration with usage components

• Secure payment processing and compliance
• Customer payment method storage
• Transaction processing and failure handling
• Payment link generation and checkout

​

Prerequisites

• You have an active Flexprice account
• You have a Razorpay account (in test or live mode)
• You possess admin access to both platforms
• You have a basic understanding of webhooks (optional but helpful)

​

Step 1: Set Up the Connection

​

Required Webhook Events

payment.captured
payment.failed

​

Step 2: Sync Configuration Details

​

Invoice Outbound Sync (Flexprice → Razorpay)

• What it does: Sends invoices generated in Flexprice to Razorpay for payment processing
• When to enable: You create invoices in Flexprice but want Razorpay to handle payment collection
• Benefits: Unified payment experience and centralized transaction history

​

Invoice Sync Timing

• Invoice is finalized (status changes from DRAFT to FINALIZED)
• Invoice outbound sync is enabled in the Razorpay connection
• Customer is successfully synced to Razorpay

​

Invoice Sync Process

1. Invoice Finalization: Invoice is finalized in Flexprice
2. Customer Sync Check: System ensures customer exists in Razorpay
3. Invoice Creation: Invoice is created in Razorpay with all line items
4. Payment URL Generation: Razorpay automatically generates payment URL
5. Mapping Storage: Flexprice stores the mapping between Flexprice and Razorpay invoices

​

Invoice Sync Features

• Automatic Sync: Invoices sync automatically when finalized
• Line Item Preservation: All invoice line items are preserved in Razorpay
• Payment URL: Razorpay generates payment URL automatically
• Duplicate Prevention: System prevents duplicate invoice creation

​

Step 3: Payment Flow Setup

​

3.1 Supported Payment Methods

1. Payment Links – For one-time payments via Razorpay Checkout
2. Invoice Payments – Payments made through synced invoices

​

3.2 Payment Collection Modes

​

3.3 Currency Minimums

• Amounts are automatically converted to smallest currency units (paise for INR, cents for USD)
• Ensure all payment amounts meet these minimums
• Invoice amounts must also meet minimum requirements

​

Step 4: Customer Synchronization

​

On-Demand Customer Sync

• Payment Link Creation: Customer is synced before creating payment link
• Invoice Sync: Customer is synced before syncing invoice

​

Customer Sync Features

• Automatic Sync: No manual intervention required
• Duplicate Prevention: System prevents duplicate customer creation
• Metadata Linking: Customer IDs are stored in metadata for quick lookup
• Email-Based Matching: Uses email for customer matching

​

Step 5: Payment Links

​

Creating Payment Links

{
  "amount": 100,
  "currency": "inr",
  "destination_id": "inv_01K34HYZN03V6X8Q6V3T8X6G4F",
  "destination_type": "INVOICE",
  "payment_method_type": "PAYMENT_LINK",
  "process_payment": true,
  "payment_gateway": "razorpay",
  "success_url": "https://admin.flexprice.io/customer-management/invoices/inv_01K34HYZN03V6X8Q6V3T8X6G4F?page=1"
}

​

Payment Link Features

• Auto-generated URLs: Razorpay automatically generates short payment URLs
• Multiple Payment Methods: Supports cards, UPI, netbanking, wallets
• Mobile Optimized: Responsive checkout experience
• Real-time Updates: Webhook-driven status updates

​

Step 6: Webhook Configuration

​

Required Webhooks

​

Webhook URL Format

https://api.cloud.flexprice.io/v1/webhooks/razorpay/{tenant_id}/{environment_id}

​

Webhook Processing

• Signature Verification: All webhooks are verified for security
• Idempotency: Duplicate webhooks are handled gracefully
• Error Handling: Errors are logged but don’t fail webhook processing
• Automatic Reconciliation: Payments are automatically reconciled with invoices

​

Best Practices

​

Currency Handling

1. Minimum Amounts: Always ensure amounts meet currency minimums
2. Currency Conversion: Amounts are automatically converted to smallest units
3. Consistent Currency: Use consistent currency across invoice and payment

​

Invoice Sync

1. Enable Sync: Enable invoice outbound sync in connection settings
2. Finalize Invoices: Only finalized invoices are synced
3. Customer Sync: Ensure customers are synced before invoice sync

​

Payment Links

1. Amount Validation: Validate amounts against invoice remaining balance
2. Currency Matching: Ensure payment currency matches invoice currency
3. Callback URLs: Provide callback URLs for better user experience

​

Error Handling

1. Monitor Webhooks: Regularly check webhook delivery logs
2. Review Logs: Check application logs for sync errors
3. Retry Failed Syncs: Retry failed syncs manually if needed

​

Troubleshooting

​

Common Issues

​

Debug Steps

1. Check Connection: Verify Razorpay connection is active
2. Check Customer Sync: Ensure customer is synced to Razorpay
3. Check Invoice Status: Verify invoice is finalized
4. Check Webhooks: Verify webhook configuration in Razorpay
