Fintech customers expect instant communication and effortless repayment journeys, whether it's loan EMIs, subscription renewals, or overdue payments. Delayed reminders, manual follow-ups, and complicated payment flows often lead to lower repayment rates and operational inefficiencies.

To help fintech companies streamline this process, Pingbix proposes an automated payment reminder workflow powered by webhooks, WhatsApp Business API, Payment Links, and unique QR-code generation. This setup ensures real-time notifications, one-click payment actions, and smooth reconciliation.

Now, let’s break down how this workflow actually works.

Below is the complete reminder-to-payment journey Pingbix can implement for your fintech platform.

1. Payment Due Detection (Webhook #1)

Your backend system identifies when a customer’s payment becomes due, whether it’s an EMI, invoice, subscription, or loan repayment. The moment the due date hits, your system triggers a webhook to Pingbix. This webhook contains all essential details:

  • Customer name or ID
  • Phone number or email
  • Payment amount
  • EMI or invoice reference
  • Due date

Pingbix receives this event instantly and prepares a personalized reminder message.

2. Pingbix Generates a Payment Link & QR Code (Webhook #2)

Pingbix then sends a server-side API call to a Payment Gateway, requesting:

  • A unique payment link
  • A transaction-specific QR code These are generated in real time and tied to the customer’s exact payment reference.

This ensures:

 - Accuracy
 - Security
 - Individual tracking
 - No mix-ups between customer payments

3. Automated Reminder Sent to the Customer

Once the Payment Gateway returns the link and QR, Pingbix automatically pushes a reminder message through the customer’s preferred channel:

  • WhatsApp Business API (highest engagement rate)
  • SMS
  • Email

The reminder includes:

  • The due amount
  • The payment link
  • The QR code
  • Customer reference details

The customer can instantly click the link or scan the QR to complete the payment.

4. Seamless Payment Completion

The customer is redirected to a secure Payment Gateway, where they can choose from multiple payment modes:

- UPI
- Net Banking
- Debit/Credit Card
- Wallets

The experience is fast, reliable, and frictionless, which reduces repayment drop-offs.

5. Real-Time Payment Confirmation Returned to Your System

Once the customer completes the transaction, the Payment Gateway sends back a detailed response in JSON format, including:

  • Payment ID
  • Status (success/failed/pending)
  • Timestamp
  • Payment method
  • Click/scan logs
  • UPI transaction reference (if applicable)

Your system can automatically store this for:

  • Backend updates
  • Transaction validation
  • Payment reconciliation

  • Customer notifications

    Data Access, Tracking & Reconciliation

Your operations or finance team can view and analyze the payment records through:

  • The payment gateway’s dashboard
  • API-based payment status checks
  • Excel/CSV exports for internal reporting

This ensures a smooth, transparent, audit-friendly payment lifecycle.
