How do you integrate Samsara, Motive, and Geotab with a carrier TMS?
Connect each telematics provider through a separate authenticated adapter, then normalize driver, vehicle, location, and duty-status events into a shared event ledger. Reconcile identifiers and timestamps, retain provider evidence, and publish only validated updates to the TMS with duplicate protection and a visible stale-data fallback.

Define the decision before choosing the interface
A position on a map, an engine odometer reading, a driver duty-status event, and a dispatcher assignment describe different facts. Start with the business decision: shipment visibility, maintenance scheduling, driver availability, or invoice evidence. Record the authoritative source, acceptable age, units, and person responsible for an exception for each field.
This reference design separates ingestion from operational writes. A slow provider should make its data visibly stale rather than freeze order entry. McLeod LoadMaster, TMW, and a carrier's SQL Server or PostgreSQL integration ledger require version-specific interfaces and permissions. An available API endpoint is not evidence that a particular TMS release supports the intended write.
Keep provider behavior inside separate adapters
Samsara's quickstart describes scoped API tokens and bearer authentication. Use minimum permissions. Its rate-limit guidance documents HTTP 429 and Retry-After. Handle those responses in the adapter instead of increasing polling across every vehicle.
Motive's Webhooks V1 documentation describes signed deliveries and receiver response expectations. Verify the signature using the mechanism for the subscribed version. Acknowledge after durable receipt and process asynchronously so a successful reply does not depend on a long TMS transaction.
Geotab's data feed uses GetFeed with a version cursor. Persist the returned cursor after its batch is durably recorded and recoverable. Deliberately choose current-state or historical seeding at deployment. Losing a cursor and restarting from now can leave an undiscovered gap.
Create a durable identity and event model
Store tenant, provider, source event ID or cursor, object ID, event type, occurred-at UTC, received-at UTC, payload version, and raw-payload reference. Preserve original timezone information. Receipt time measures your pipeline; event time describes the operation.
| Mapping | Control | Exception |
|---|---|---|
| Provider vehicle to TMS tractor | Effective-dated mapping | Reused unit number |
| Provider driver to TMS driver | Stable IDs and assignment history | Driver swap |
| Vehicle event to stop | Assignment and time-window match | Multiple loads at one facility |
Team driving, shop moves, loaner tractors, and reassigned equipment require an effective interval. Keep ambiguous events in a review queue instead of silently selecting the first load. J1939-derived readings may already be interpreted by the provider; preserve signal identity, unit, and quality metadata when available rather than assuming raw CAN-bus access.
Separate ingestion from publication
The receiver verifies credentials, checks payload size, durably records the source event, and returns a receipt. A normalizer converts fields without removing provenance. A reconciliation worker resolves identities and sequence. A publisher writes through the supported TMS interface and records the acknowledgment. Give each stage a retry budget and observable queue.
Use a unique provider event key when available. Otherwise document a deterministic fingerprint and its collision limitations. A replay should update the same normalized record rather than create another business effect. Preserve failed payloads and reason codes. Authentication failures need an integration owner, not an endless rapid retry loop.
Keep secrets outside source code and application logs. Isolate access by tenant, rotate credentials through an agreed procedure, and test a revoked token. Store operational data according to a documented retention and access policy; keeping an event ledger does not require unrestricted access to every driver's history.
Make uncertainty visible and test recovery
Display the last source-event time and stale status beside availability recommendations. Proximity alone cannot prove current driver availability or loading completion. Route uncertain dispatch decisions to the responsible operations and safety staff. A customer feed can show the last confirmed location; an automated planning assistant can stop recommendations; a settlement workflow can hold an unsupported adjustment.
Test duplicate and out-of-order events, a driver swap, daylight-saving transitions, expired credentials, throttling, queue saturation, and restart between commit and cursor advancement. Reprocess a recorded batch and confirm effects do not multiply. Use the actual TMS sandbox and supported permissions.
Measure source-event age, publication lag, unknown identifiers, rejected payloads, cursor age, and exhausted retries. Set workflow-specific thresholds with operations. Pilot a small asset group, reconcile against provider dashboards, and keep a disable switch that leaves manual dispatch available.
Frequently asked questions
Can the three providers share one integration pipeline?
Yes. Separate adapters can feed a common event ledger while preserving provider identifiers, timestamps, authentication rules, and replay behavior.
Does a location ping prove driver availability?
No. Location, driver assignment, duty status, data age, and operational constraints must be evaluated separately.
When should a Geotab cursor advance?
Advance the persisted cursor after its batch is durably recorded and can be recovered without losing events.
