🎓 Key Concepts

GraphQL vs REST

REST v2 (Current):

// Multiple endpoints
GET /cases
GET /cases/:id
GET /cases/:id/activities
GET /cases/:id/materials

GraphQL (New):

// 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

// REST v2
auth: { username: apiToken, password: 'x' }

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