Work Orders API

Read work orders from LambdaAssetCheck and update them from your CMMS with status changes, root cause, resolution, closure details, completion time, and actual hours.

Authentication

GET endpoints (list, get by ID) use the same API key (Bearer or Basic auth) as other v1 APIs. See Authentication.

POST endpoint (update) uses a Bearer token + X-API-KEY configured in your organization's downstream integration settings (Admin → Settings → Downstream Integration).

Quick reference

Method	Path	Description
`GET`	`/api/v1/work-orders`	List work orders (paginated, filterable)
`GET`	`/api/v1/work-orders/{id}`	Get a single work order with linked tasks and time tracking
`POST`	`/api/downstream/work-orders/{id}/sync`	Update a work order — status, root cause, resolution, closure note, completion time, actual hours

List work orders

Retrieve all work orders for the authenticated organization. Returns paginated results with time tracking.

Get by ID includes tasks with time tracking

The single work order response includes linked tasks with per-task estimatedHours, actualHours, startedAt, completedAt. The list endpoint does not include tasks.

Update a work order

Push status changes, root cause, resolution, closure details, completion time, and actual hours from your CMMS back to LambdaAssetCheck. All fields are optional — send only what changed. You can call this endpoint multiple times; each call updates only the fields you include.

Prerequisites

1. Downstream integration must be configured and active (Admin → Settings → Downstream Integration).

2. Uses Bearer token + X-API-KEY from your downstream integration settings (different from the v1 API key used for GET endpoints above).

3. The Work Order id is included in the payload when LambdaAssetCheck originally pushes the item to your CMMS.

Request body fields

Field	Type	Required	Description
`externalId`	string	No	Your CMMS reference number / ticket ID
`status`	enum	No	`DRAFT` \| `ASSIGNED` \| `IN_PROGRESS` \| `ON_HOLD` \| `COMPLETED` \| `CANCELLED`
`externalStatus`	string	No	Status label as it appears in your CMMS (free-text)
`externalUrl`	string (URL)	No	Deep link to this work order in your CMMS
`rootCause`	string (max 500)	No	Root cause category or description
`resolution`	string (max 2000)	No	What was done to resolve the issue
`closureNote`	string (max 2000)	No	Additional closure notes or follow-up recommendations
`completedAt`	string (ISO 8601)	No	When the work was completed (e.g. `2026-03-10T14:30:00.000Z`)
`actualHours`	number	No	Actual hours spent (e.g. `4.5`)
