BigChange API
BigChange (BigChange Lightning) is an AI-powered field service management platform combining job scheduling, CRM, a mobile workforce app, vehicle tracking, and financial management for mobile service teams. An API lets you programmatically pull jobs, contacts, resources, schedules, vehicles, assets, and invoices—and push updates like new jobs, job statuses, and customer records back into BigChange.
What is BigChange?
BigChange (BigChange Lightning) is an AI-powered field service management platform that combines workforce management, job scheduling, and business intelligence to help mobile service teams operate more efficiently. Service businesses use BigChange to plan and dispatch jobs, manage customer relationships, equip engineers with a mobile app, track vehicles and time via GPS, manage assets, and handle invoicing and payments—then connect it all to their wider tech stack through the BigChange Developer REST API.
Core product areas include:
- Job Scheduling and dispatch for mobile field teams
- CRM for managing customer contacts and relationships
- Mobile App and workforce management for engineers in the field
- Vehicle Tracking and GPS time tracking
- Financial Management, invoicing, and payment processing
- Asset Management and stock control
- AI agents (JustAsk, FieldReady, JobReady, JobScribe, JobBrief) and business intelligence reporting
Common data entities:
- Jobs, Job Types, Job Statuses, Schedules
- Contacts, Customers, Sites, CRM records
- Resources/Engineers, Vehicles, Timesheets, GPS tracks
- Assets, Stock, Equipment
- Invoices, Payments, Financial documents
- Custom Fields, Worksheets, Documents and Attachments
The BigChange Integration Challenge
Service businesses run scheduling, dispatch, and field operations on BigChange every day, but turning that activity into reliable API-driven automation involves real friction:
- API key gating: REST API access is controlled by securely generated keys and per-user permissions, so integrations only see the data a given account is entitled to
- Mobile-first field data: Much of the richest data (job completion, signatures, photos, GPS) originates in the engineer mobile app and must be reconciled with back-office records
- Custom fields and worksheets: Each customer configures their own job types, custom fields, and worksheet templates, so generic integrations break across accounts
- Mixed API surfaces: Newer REST endpoints sit alongside older web-services calls, and coverage varies by entity and account configuration
- Real-time scheduling state: Live dispatch, ETAs, and job statuses change constantly, so polling has to be tuned to avoid stale data and rate pressure
- Financial and stock workflows: Invoices, payments, and stock movements need careful sequencing and idempotency to keep accounting integrations clean
How Supergood Creates BigChange APIs
Supergood combines BigChange's REST API, authenticated web-services flows, and the engineer-facing surfaces into a single resilient API layer for your BigChange account—so you integrate once and rely on consistent objects regardless of how your account is configured.
- Manages API key authentication and per-user permission scopes securely in a managed session
- Maintains session continuity with automated refresh and change detection
- Normalizes responses across Jobs, Contacts, Resources, Vehicles, Assets, and Invoices into consistent objects
- Preserves account-specific job types, custom fields, and worksheet templates rather than forcing a generic schema

Frequently asked questions
Yes. BigChange offers a Developer REST API with securely generated API keys and tightly controlled, per-user permissions. Supergood works against that API plus authenticated web-services surfaces to deliver complete, normalized coverage of your account's data.
Each account is profiled against its configured job types, custom fields, and worksheet templates. Supergood preserves these account-specific fields and lifecycle states rather than forcing a generic schema.
Yes. The API supports creating and updating jobs, statuses, contacts, and financial records, so you can automate dispatch and back-office workflows in both directions.
Yes. Job completion, signatures, photos, timesheets, and GPS tracking that originate in the engineer mobile app are reconciled with back-office records and exposed through the same normalized API surface.
Invoices, payments, and stock movements are exposed for reconciliation with accounting systems, and the API supports low-code tools like Power Automate alongside direct integration, so you can connect BigChange to your wider tech stack.
