[FEAT]:Checkout Process - Backend

[King-Mikaelson]

Description

Develop an endpoint to handle the checkout process, including payment processing

Acceptance Criteria

Automated Checkout System:

• Implement server-side logic to handle plan purchases.

• Integrate with a secure payment gateway to handle payments.

  User Preferences

• Store purchase details securely in the database.

• Handle user-specific configurations and preferences related to the checkout process.

  Security Measures

• Use HTTPS for secure data transmission.

• Validate user input on the server side.

• Encrypt sensitive data such as payment information.

Purpose

To allow users to complete their purchases securely and efficiently.

Requirements

• [ ] Develop server-side logic to process payments.
• [ ] Securely store purchase details in the database.
• [ ] Ensure compliance with security standards for handling payment information.

Payment Handling

• Log successful transactions.
• Implement retry mechanisms for failed transactions.

Expected Outcome

1. The backend should handle plan purchases securely and efficiently.
2. The system should log transactions and handle errors appropriately.

Endpoints

Checkout Process:

Description: Process the checkout and payment for the selected plan. Endpoint: POST /api/checkout Request Body: json

{
  "userId": "String",
  "planId": "String",
  "paymentDetails": {
    "cardNumber": "String",
    "expiryDate": "String",
    "cvv": "String"
  }
}

Response (Success): json

{
  "message": "Payment successful. Plan activated.",
  "transactionId": "String"
}

Response (Error): json

{
  "message": "Payment failed",
  "statusCode": 400
}

Tasks

• [ ] Implement the POST /api/checkout endpoint.
• [ ] Validate the request body for necessary fields and correct formats.
• [ ] Integrate with a secure payment gateway (e.g., Stripe, PayPal) to process payments.
• [ ] Handle payment gateway responses and errors.
• [ ] Create a schema for storing purchase details.
• [ ] Securely store transaction details and user information.
• [ ] Ensure compliance with security standards (e.g., PCI-DSS) for handling payment information.

Testing

1. Write unit tests for the POST /api/checkout endpoint.
2. Write unit tests for validation and error handling logic.
3. Write integration tests for the end-to-end checkout process.
4. Test integration with the payment gateway.
5. Perform security testing to ensure compliance and data protection.
6. Test encryption and secure storage of sensitive data.
7. Test the full flow from plan selection to payment completion.
8. Ensure the system handles successful and failed transactions appropriately.
