## 🔌 Internal API Architecture

### **Frontend-Backend Communication**

The Shift.fun platform uses internal API routes to facilitate communication between the frontend and backend services. These APIs are not publicly exposed and are designed for secure internal operations.

<Steps>
  <Step title="Migration Management APIs">
    Internal APIs for managing token migrations:

    * Create and configure migration entries
    * Track migration progress and status
    * Execute migration operations
    * Manage user participation
  </Step>

  <Step title="IP Services APIs">
    Internal APIs for IP protection services:

    * Process IP protection applications
    * Manage application status and workflow
    * Handle payment verification
    * Track registration progress
  </Step>

  <Step title="Authentication APIs">
    Secure authentication and authorization:

    * User login and session management
    * Role-based access control
    * JWT token validation
    * Admin authentication
  </Step>
</Steps>

### **API Security**

<Note>
  **Internal Use Only**: All APIs are designed for internal frontend-backend communication and are not publicly accessible. They include comprehensive security measures and authentication requirements.
</Note>

* **Authentication Required**: All internal API calls require valid JWT tokens
* **Role-Based Access**: Different API endpoints require appropriate user roles
* **Rate Limiting**: Protection against abuse and DDoS attacks
* **Input Validation**: Comprehensive validation of all API inputs
* **Secure Communication**: All API communication is encrypted and secured
