An ELD-dispatch integration is successful only when identity, time, vehicle assignment, status, messages, and exceptions remain consistent across both systems. A connector that moves data without clear ownership can create duplicate or conflicting records.
What this means for your fleet
Map each field and direction before enabling automation. Define which system is authoritative, how retries and duplicates are handled, who monitors failures, and how access is revoked.
Integration field map and write boundary
| Field or event | System of record | Allowed direction | Failure test |
|---|---|---|---|
| Driver and vehicle identity | Named master data owner | Create/update only through approved identity workflow | Duplicate driver, tractor swap, deactivated account |
| Dispatch assignment and stop | Dispatch system | May inform the ELD workflow; must not falsify duty status | Cancelled load, reassignment, late timestamp |
| Duty status and original ELD event | ELD record | Read for planning; edits only through governed ELD process | Conflicting status, proposed edit, driver rejection |
| Location and ETA | Define required ELD versus optional telematics source | Read with timestamp and precision | Offline gap, stale point, wrong vehicle |
Before connecting production, document authentication, least-privilege scopes, retry/idempotency, clock/time-zone rules, audit logs, retention, revocation, and rollback. Factor’s current API or connector availability must be confirmed in writing.
What to check
Use these checks before changing a log, policy, device, integration, or buying decision.
| Check | How to verify |
|---|---|
| 1. Map driver vehicle and time identifiers | Keep a field-level map for driver, vehicle, time, status and message identifiers, including direction, format, owner, and unmatched-ID handling. |
| 2. Choose a system of record | Record the authoritative system for each field, who may change it, conflict precedence, approval date, and the test that proves the rule is enforced. |
| 3. Test duplicate and retry behavior | Run duplicate, delayed, out-of-order and failed-delivery payloads; retain IDs, timestamps, retry count, observed result, reconciliation, and defect closure. |
| 4. Limit API permissions | Export the integration credentials and permissions, test least privilege, rotate or revoke access, and preserve the denied-action and shutdown results. |
| 5. Monitor exceptions and reconcile daily | Keep the daily exception queue, owner, aging rule, source-versus-destination comparison, correction, closed count, unresolved items, and next review. |
Common failure modes
- Matching drivers by display name.
- Two-way writes without conflict rules.
- Letting integration errors alter certified logs.
Limits and exceptions
This guide does not decide a fact-specific legal exception, certify a record, or guarantee a compliance, safety, cost, or audit outcome. Keep the original ELD record and any edit history. Use the current official rule for applicability and the exact installed-device manual for screen-by-screen actions.

Test one complete day before fleet rollout
Use a real vehicle and driver to test login, duty status, edits, certification, unidentified driving, offline recovery, roadside transfer, and malfunction fallback. Factor ELD can demonstrate its current product; rule applicability remains a fleet compliance decision.
