MaintainX Hello World

Overview

Create your first work order using the MaintainX REST API -- the core building block of CMMS operations.

Prerequisites

• Completed maintainx-install-auth setup
• Valid MAINTAINX_API_KEY environment variable
• Node.js 18+ or curl

Instructions

Step 1: Create a Work Order (curl)

curl -X POST https://api.getmaintainx.com/v1/workorders \
  -H "Authorization: Bearer $MAINTAINX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Hello World - Test Work Order",
    "description": "First API-created work order. Safe to delete.",
    "priority": "LOW",
    "status": "OPEN"
  }' | jq .

Expected response:

{
  "id": 12345,
  "title": "Hello World - Test Work Order",
  "status": "OPEN",
  "priority": "LOW",
  "createdAt": "2026-03-19T12:00:00Z"
}

Step 2: Create a Work Order (TypeScript)

// hello-maintainx.ts
import { MaintainXClient } from './maintainx/client';

async function helloMaintainX() {
  const client = new MaintainXClient();

  // Create a basic work order
  const { data: workOrder } = await client.createWorkOrder({
    title: 'HVAC Filter Replacement - Building A',
    description: 'Replace air filters in units 1-4 on the 3rd floor.',
    priority: 'MEDIUM',
  });
  console.log('Created work order:', workOrder.id);

  // Retrieve it back to confirm
  const { data: fetched } = await client.getWorkOrder(workOrder.id);
  console.log('Work order status:', fetched.status);
  console.log('Created at:', fetched.createdAt);

  // List open work orders
  const { data: list } = await client.getWorkOrders({
    status: 'OPEN',
    limit: 5,
  });
  console.log(`Found ${list.workOrders.length} open work orders`);
}

helloMaintainX();

Step 3: Verify and Clean Up

# List recent work orders to confirm creation
curl -s "https://api.getmaintainx.com/v1/workorders?limit=3" \
  -H "Authorization: Bearer $MAINTAINX_API_KEY" | jq '.workOrders[] | {id, title, status}'

# Delete the test work order (replace ID)
curl -X DELETE "https://api.getmaintainx.com/v1/workorders/12345" \
  -H "Authorization: Bearer $MAINTAINX_API_KEY"

Output

• Working code file that creates a MaintainX work order via REST API
• Console output showing the created work order ID, status, and timestamp
• Verified retrieval of the created work order

Error Handling

Error	Cause	Solution
400 Bad Request	Missing required title field	Include at least title in the POST body
401 Unauthorized	Invalid API key	Check MAINTAINX_API_KEY environment variable
403 Forbidden	Plan limitations	Verify API access on your subscription
422 Unprocessable	Invalid enum value	Use valid priority (NONE, LOW, MEDIUM, HIGH)

Examples

Create a work order tied to an asset:

const wo = await client.createWorkOrder({
  title: 'Conveyor Belt #7 - Bearing Replacement',
  description: 'Replace worn bearings on the main drive shaft.',
  priority: 'HIGH',
  assetId: 98765,       // Link to equipment asset
  locationId: 54321,    // Link to facility location
  assignees: [{ type: 'USER', id: 111 }],
  dueDate: '2026-03-25T17:00:00Z',
});

Create a work order from a preventive maintenance template:

curl -X POST https://api.getmaintainx.com/v1/workorders \
  -H "Authorization: Bearer $MAINTAINX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Monthly Fire Extinguisher Inspection",
    "priority": "MEDIUM",
    "categories": ["PREVENTIVE"],
    "procedureId": 7890
  }'
