## 🎓 Key Concepts

### GraphQL vs REST
**REST v2** (Current):
```javascript
// Multiple endpoints
GET /cases
GET /cases/:id
GET /cases/:id/activities
GET /cases/:id/materials
```

**GraphQL** (New):
```javascript
// Single endpoint, flexible queries
POST /graphql
{
  query GetCase($id: Int!) {
    case(id: $id) {
      id
      activities { ... }
      materials { ... }
    }
  }
}
```

### API Endpoints
- **REST v1** (Deprecated): `https://api.ordrestyring.dk`
- **REST v2** (To Replace): `https://v2.api.ordrestyring.dk`
- **GraphQL Production**: `https://graphql.ordrestyring.dk/graphql`
- **GraphQL Beta** (Current): `https://beta7-api.ordrestyring.dk/graphql`

### Authentication
```javascript
// REST v2
auth: { username: apiToken, password: 'x' }

// GraphQL
headers: { 'Authorization': `Bearer ${apiToken}` }
```
