BigChange
BigChange is an all-in-one field service and job management platform (CRM, job scheduling, live tracking, a mobile workforce app, job finance, and business intelligence) known as JobWatch. Its modern REST API - the BigChange DX API at https://api.bigchange.com - lets developers manage jobs, contacts and persons, quotes, invoices and purchase orders, stock, resources, users and vehicles, worksheets, and assets, plus subscribe to webhooks. Requests are authenticated with a Bearer JWT access token (obtained through BigChange's authentication proxy from a developer-portal API key) and scoped with a required Customer-Id header.
BigChange publishes 11 APIs on the APIs.io network, including Assets API, Contacts API, Finance API, and 8 more. Tagged areas include Field Service Management, Job Management, Scheduling, Workforce Management, and Fleet.
BigChange’s developer surface includes authentication, documentation, engineering blog, and 7 more developer resources.
