export default PaymentReminderForm;

3. Pydantic Data Schema

from pydantic import BaseModel
from typing import Optional

class CreatePaymentReminder(BaseModel):
    customer_id: int
    amount: float
    due_date: str
    callback_url: Optional[str] = None
    
    # Example optional fields
    description: Optional[str] = None
    payment_method_id: Optional[int] = None
    
    @classmethod
    def example(cls):
        return {
            "customer_id": 12345,
            "amount": 5000.99,
            "due_date": "2024-03-15",
            "callback_url": "https://api.example.com/notifications"
        }

Explanation

The code samples provide a complete implementation of the Payment Reminder System:

  1. FastAPI Endpoint: Handles creating payment reminders with proper validation, error handling, and database integration.

  2. React UI: A simple form component for submitting payment reminder details to the backend API.

  3. Pydantic Schema: Defines the data structure for payment reminders, including optional fields and an example method.

These examples work together to demonstrate a full-stack implementation of the Payment Reminder System module.

Payment Reminder System Module Documentation

Overview

The Payment Reminder System module is designed to send automated reminders for upcoming payments or renewals to reduce customer churn. This system integrates seamlessly with payment processing, subscription management, and notification modules to ensure timely reminders are sent to users.

Use Cases

  1. Send Renewal Reminder: Trigger an email reminder 7 days before a subscription renewal date.
  2. Overdue Payment Follow-up: Send automated emails or SMS messages to customers with overdue payments.
  3. Invoice Due Date Reminder: Alert users when an invoice is approaching its due date.
  4. Grace Period Reminders: Send reminders during the grace period for late payments.
  5. Bulk Payment Processing: Handle bulk payment reminders for multiple users.
