# MaintainX Core Workflow A: Work Order Lifecycle

## Overview
Master the complete work order lifecycle in MaintainX -- from creation through completion. Work orders are the core unit of maintenance operations.

## Prerequisites
- Completed `maintainx-install-auth` setup
- `MAINTAINX_API_KEY` environment variable configured
- MaintainX account with work order permissions

## Status Transition Flow

```
OPEN ──→ IN_PROGRESS ──→ COMPLETED ──→ CLOSED
  │           │               ↑
  │           ↓               │
  │        ON_HOLD ───────────┘
  │
  └──→ CLOSED (cancelled)
```

## Instructions

### Step 1: Create a Work Order

```typescript
import { MaintainXClient } from './maintainx/client';

const client = new MaintainXClient();

// Create a corrective work order
const { data: wo } = await client.createWorkOrder({
  title: 'Pump Station #3 - Seal Leak Repair',
  description: 'Detected water leak at the mechanical seal. Needs immediate attention.',
  priority: 'HIGH',
  status: 'OPEN',
  assignees: [{ type: 'USER', id: 4521 }],
  assetId: 8901,
  locationId: 2345,
  dueDate: '2026-03-21T17:00:00Z',
  categories: ['CORRECTIVE'],
});

console.log(`Work order #${wo.id} created`);
```

### Step 2: Update Status Through Lifecycle

```typescript
// Technician starts work
await client.updateWorkOrder(wo.id, {
  status: 'IN_PROGRESS',
});

// Put on hold (waiting for parts)
await client.updateWorkOrder(wo.id, {
  status: 'ON_HOLD',
  onHoldReason: 'Waiting for replacement seal kit from supplier',
});

// Resume and complete
await client.updateWorkOrder(wo.id, {
  status: 'IN_PROGRESS',
});

await client.updateWorkOrder(wo.id, {
  status: 'COMPLETED',
  completionNotes: 'Replaced mechanical seal. Tested for 30 min with no leaks.',
});
```

### Step 3: Query Work Orders

```typescript
// Fetch open work orders sorted by priority
const { data: openOrders } = await client.getWorkOrders({
  status: 'OPEN',
  limit: 25,
});

for (const order of openOrders.workOrders) {
  console.log(`#${order.id} [${order.priority}] ${order.title}`);
}

// Paginate through all IN_PROGRESS orders
async function getAllInProgress() {
  const allOrders = [];
  let cursor: string | undefined;

  do {
    const { data } = await client.getWorkOrders({
      status: 'IN_PROGRESS',
      limit: 100,
      cursor,
    });
    allOrders.push(...data.workOrders);
    cursor = data.cursor;
  } while (cursor);

  return allOrders;
}
```

### Step 4: Add Comments and Attachments

```typescript
// Add a technician note
await client.request('POST', `/workorders/${wo.id}/comments`, {
  body: 'Arrived on site. Isolating pump before disassembly.',
});

// Add a completion photo (URL-based)
await client.request('POST', `/workorders/${wo.id}/files`, {
  url: 'https://storage.example.com/photos/seal-repair-complete.jpg',
  name: 'seal-repair-complete.jpg',
});
```

### Step 5: Assign to Teams

```typescript
// Assign to a team instead of individual
const { data: teams } = await client.request('GET', '/teams');
const mechTeam = teams.teams.find((t: any) => t.name === 'Mechanical');

await client.updateWorkOrder(wo.id, {
  assignees: [{ type: 'TEAM', id: mechTeam.id }],
});
```

## Output
- Work orders created with full metadata (title, description, priority, assignees, asset, location)
- Status transitions executed through the complete lifecycle
- Paginated query results for filtering work orders
- Comments and files attached to work orders

## Error Handling
| Error | Cause | Solution |
|-------|-------|----------|
| 400 Bad Request | Missing `title` field | Include at least `title` in POST body |
| 404 Not Found | Invalid asset/location/user ID | Verify referenced IDs exist via GET endpoints |
| 403 Forbidden | Insufficient permissions | Check user role has work order write access |
| 422 Invalid transition | Invalid status change (e.g., CLOSED to OPEN) | Follow the status transition flow above |

## Examples

**Bulk-create preventive maintenance work orders**:

```typescript
const pmSchedule = [
  { title: 'Weekly HVAC Filter Check', priority: 'LOW', categories: ['PREVENTIVE'] },
  { title: 'Monthly Fire Extinguisher Inspection', priority: 'MEDIUM', categories: ['PREVENTIVE'] },
  { title: 'Quarterly Elevator Safety Audit', priority: 'HIGH', categories: ['PREVENTIVE'] },
];

for (const pm of pmSchedule) {
  const { data } = await client.createWorkOrder(pm);
  console.log(`PM created: #${data.id} - ${data.title}`);
}
```

**Filter work orders by date range**:

```bash
curl -s "https://api.getmaintainx.com/v1/workorders?createdAtGte=2026-03-01T00:00:00Z&createdAtLte=2026-03-31T23:59:59Z&limit=50" \
  -H "Authorization: Bearer $MAINTAINX_API_KEY" | jq '.workOrders | length'
```
