Fleet.io API
Fleetio is fleet management software used by businesses to manage vehicles and equipment, drivers/contacts, maintenance and work orders, inspections (DVIR), fuel and costs, and telematics integrations. An unofficial API lets you programmatically pull vehicle lists, assignments, meter
What is Fleetio?
Fleetio is a cloud platform for fleet management that centralizes asset tracking, driver assignments, maintenance, inspections, fuel, and vendor relationships. Teams use Fleetio to control in-service status, track odometer/meter readings, manage work orders and service entries, process fuel and cost data, record DVIR inspections and defects, and integrate with telematics and fuel card providers.
Core product areas include:
- Vehicle & Equipment Management (assets, VIN/serials, groups, assignments)
- Maintenance Management (issues/defects, service entries, work orders, reminders)
- Fuel & Costs (fuel transactions, MPG/consumption, cost reporting)
- Inspections & DVIR (forms, pass/fail items, defect logging, resolution)
- Drivers & Contacts (roles, permissions, assignments)
- Integrations (telematics, fuel cards, vendors)
Common data entities:
- Vehicles and Equipment (asset metadata, status, meter readings)
- Drivers/Contacts and Permissions
- Work Orders and Service Entries
- Issues/Defects and Resolution history
- Inspections (DVIR) and Item Results
- Fuel Entries and Cost Details
- Odometer/Meter Logs and Locations
- Vendors, Shops, and Parts/Inventory
- Reminders (registration, insurance, PM schedules)
The Fleetio Integration Challenge
Fleet teams rely on Fleetio daily, but turning portal-based workflows into API-driven automation can be tricky:
- Module-specific interfaces: Assets, Maintenance, Inspections, and Fuel each have distinct data models and entitlement rules
- Enterprise security: SSO, MFA, and role-based controls complicate headless automation for background jobs
- Portal-first features: Some capabilities (attachments, approvals, custom fields) are optimized for the web app and unevenly documented
- Coverage gaps and variance: Telematics integrations, inspection schemas, and vendor workflows may differ between accounts, causing mapping complexity
- Rate limits and pagination: High-volume sync of meter readings, fuel transactions, and inspections requires careful batching and retry logic
How Supergood Creates Fleetio APIs
Supergood reverse-engineers authenticated browser flows and network interactions to deliver a resilient API endpoint layer for your Fleetio tenant.
- Handles username/password, SSO/OAuth, and MFA (SMS, email, TOTP) securely
- Maintains session continuity with automated refresh and change detection
- Normalizes responses so you can integrate once and rely on consistent objects across modules
- Aligns with customer entitlements and role-based permissions to ensure compliant access

API Endpoints
Authentication
/sessionsEstablish a session using credentials. Supergood manages MFA (SMS, email, TOTP) and SSO/OAuth when enabled. Returns a short-lived auth token maintained by the platform.
Authentication
/sessions/refreshRefresh an existing token to keep sessions uninterrupted.
Vehicles
/vehiclesList vehicles with filters and summary details.
Service Entries
/vehicles/{vehicleId}/service-entriesCreate a new service entry with vendor, line items, and optional attachments.
Fuel Entries
/vehicles/{vehicleId}/fuel-entriesLog a fuel transaction with odometer and cost details.
Issues
/issues/{issueId}Update issue status, severity, and resolution details.
Use Cases
Fleet Data Sync
- Mirror vehicles/equipment, drivers/contacts, and groups into your internal systems - Keep asset metadata, in-service status, and meter readings current for analytics - Normalize VINs, custom fields, and location data across telematics providers
Maintenance Automation
- Create service entries and work orders from fault codes or inspection defects - Initiate issues with severity, assignments, and attachments - Track status and close-out events to drive SLA alerts and vendor workflows
Fuel and Cost Reporting
- Pull fuel card transactions to reconcile with ERP (e.g., cost centers, GL codes) - Detect anomalies (sudden MPG drops, mismatch in odometer vs. telematics) - Push fuel entries with receipts and geolocation for auditability
Driver & Compliance
- Ingest DVIR inspection results and defects for compliance reporting - Sync driver assignments and permissions into dispatch or HR systems - Manage reminders for registrations, inspections, and insurance renewals
Technical Specifications
Authentication
Username/password with MFA (SMS, email, TOTP) and SSO/OAuth where enabled; supports service accounts or customer-managed credentials
Response format
JSON with consistent resource schemas and pagination across modules
Rate limits
Tuned for enterprise throughput while honoring customer entitlements and usage controls
Session management
Automatic reauth and cookie/session rotation with health checks
Data freshness
Near real-time retrieval of vehicles, maintenance, inspections, and fuel objects
Security
Encrypted transport, scoped tokens, and audit logging; respects Fleetio role-based permissions
Webhooks
Optional asynchronous delivery for long-running workflows (e.g., work order approvals, defect resolutions)
Latency
Sub-second responses for list/detail queries under normal load
Throughput
Designed for high-volume fleet data sync and fuel transaction processing
Reliability
Retry logic, backoff, and idempotency keys minimize duplicate actions
Adaptation
Continuous monitoring for UI/API changes with rapid adapter updates
Frequently asked questions
Supergood supports workflows across commonly used modules such as Asset Management (vehicles/equipment), Maintenance (issues, service entries, work orders, reminders), Inspections (DVIR), Fuel & Costs, and Drivers/Contacts, subject to your licensing and entitlements. We scope coverage during integration assessment.
We support username/password + MFA (SMS, email, TOTP) and can operate behind SSO/OAuth when enabled. Sessions are refreshed automatically with secure challenge handling.
Yes. We can normalize fuel entries to match your ERP schema (e.g., cost centers, GL accounts) and deliver updates via webhooks or polling while complying with rate and permission constraints.
Yes. We can ingest inspection results, defects, and resolutions, including attachments, and map them to your compliance workflows. Availability may vary by account configuration and permissions.
We solve for pagination/rate limits at scale, attachment handling, custom field normalization, telematics/meter reconciliation, and permission-aware automation across modules.
