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.
