Build on CrewFlow

A versioned REST API covers the operational surface of the platform: clients, projects, jobs, workers, assignments, documents, timesheets, expenses and invoices — documented with OpenAPI and authenticated with API keys or OAuth 2.0.

Why it matters

The case for Developer API

Enterprise buyers ask one question about any platform: can we get our data out and drive it programmatically? The answer needs to be yes, with documentation.

OpenAPI

documented

Integration teams start building the same day they get credentials.

CrewFlow · Developer API
POST /v1/jobs
Authorization: Bearer <api-key>

{
  "project_id": "prj_8fa2",
  "start_date": "2026-04-06",
  "roles": [{ "trade": "pipefitter", "headcount": 8 }]
}

→ 201 { "job_id": "job_2c19", "status": "mobilising" }
