# Interoperable Application Checklist

Use this checklist to ensure that your application meets the requirements of being a modern interoperable application.

## RESTful APIs

- [ ] **API Implementation**: Have you implemented RESTful APIs to allow external systems to interact with your application?

- [ ] **Standard HTTP Methods**: Do you use standard HTTP methods (GET, POST, PUT, DELETE) for CRUD operations on resources?

- [ ] **API Documentation**: Is there comprehensive documentation available for your APIs, including endpoint descriptions, request/response formats, and authentication methods?

- [ ] **Security**: Have you implemented security measures such as authentication, authorization, and input validation for your APIs?

- [ ] **Testing**: Have you thoroughly tested your APIs using tools like Postman or curl?

## Python and Django (If applicable)

- [ ] **Django Setup**: Have you set up your Django project and app for building RESTful APIs?

- [ ] **API Views**: Have you defined API views using the `@api_view` decorator?

- [ ] **URL Patterns**: Have you configured URL patterns to map to your API views in your app's `urls.py`?

- [ ] **Serializers**: Have you created serializers for your data models using Django Rest Framework (DRF)?

- [ ] **Database Models**: Are your database models defined using Django's ORM?

- [ ] **Database Migrations**: Have you run database migrations to create the required database schema?

## Webhooks for External Notifications

- [ ] **Webhook Endpoint**: Have you defined an endpoint in your API to receive webhook notifications?

- [ ] **Security**: Have you implemented security measures to validate and authenticate incoming webhook payloads?

- [ ] **Event Triggers**: Have you identified the events that trigger webhook notifications in your application?

- [ ] **Payload Format**: Have you defined the format of the webhook payload (e.g., JSON or XML)?

- [ ] **Outbound Requests**: Do you send HTTP POST requests with the webhook payload to the specified webhook URL when events occur?

- [ ] **Retries and Acknowledgments**: Have you implemented handling for retries and acknowledgments to ensure delivery and reliability?

## Application Security

- [ ] **Authentication**: Is user authentication implemented to restrict access to authorized users?

- [ ] **Authorization**: Are access controls and permissions defined to limit what authenticated users can do within the application?

- [ ] **HTTPS**: Is HTTPS used to encrypt data transmitted between the application and clients?

- [ ] **Input Validation**: Are all user inputs properly validated to prevent common vulnerabilities?

- [ ] **API Security**: Are APIs secured with authentication tokens (e.g., JWT) and access limited to authorized clients?

- [ ] **Data Encryption**: Is sensitive data encrypted at rest and during transit?

- [ ] **Security Updates**: Are you regularly updating dependencies and applying security patches?

- [ ] **Logging and Monitoring**: Is there logging and monitoring in place to detect and respond to security incidents?

By completing this checklist, you can ensure that your application adheres to the requirements of being a modern interoperable application, capable of seamless communication and secure data exchange with other systems.
