ERP/CRM + Telematics Integration Blueprint (APIs, Webhooks, Data Maps)
Primary keyword: telematics ERP integration
Last updated: 29 Oct 2025
Connect orders, customers, and assets in ERP/CRM with live GPS, trips, fuel, and maintenance from telematics. This blueprint gives you architecture, field maps, webhook events, and security patterns—plus ready‑to‑download CSVs.
Summary: Pick a pattern (pull, push, hybrid) → map entities → subscribe to events → build idempotent jobs → monitor & retry → ship faster with the included templates.
- Resource Type: Blueprint / Guide
- Category: IT & Integrations
- Audience: IT & Integration Teams; Platform Admins; Decision Makers

- CTA assets: Data Map (CSV) • Webhook Catalog (CSV) • Integration Fields (CSV)
Reference architecture
| Pattern | When to use | Notes |
|---|---|---|
| Pull (API polling) | Small scale, nightly sync | Simpler; use updated_since cursors |
| Push (webhooks) | Near‑real‑time updates | Validate signature; enqueue work; ack fast |
| Hybrid | Most production setups | Events for realtime; periodic backfill for safety |
Core entities & IDs
- Vehicle/Asset (vehicle_id, VIN), Driver (driver_id, Emirates ID), Customer/Site (customer_id)
- Trip/Job (trip_id, ERP order_id), Fuel (fuel_txn_id), Service (work_order_id)
- Store both systems’ IDs in a mapping table; make writes idempotent.
Data map (download below)
Start with vehicles, drivers, trips, fuel, and maintenance. Specify type, format, cardinality, and system of record.
Webhook events
| Event | Payload | Typical action |
|---|---|---|
| vehicle.location.updated | vehicle_id, lat, lon, speed, ts | Update live board, delay ETA |
| trip.status.changed | trip_id, status, site_id, ts | Advance ERP order, notify customer |
| fuel.transaction.created | vehicle_id, liters, amount, ts | Reconcile against fuel cards |
| service.work_order.due | vehicle_id, task, due_date, meter | Create ERP work order |
| alert.geofence.event | vehicle_id, geofence_id, enter/exit, ts | Mark arrival/departure, dwell |
Auth & security
- OAuth2 client credentials or signed HMAC headers for webhooks.
- Use Idempotency-Key headers; detect replay via ts + HMAC.
- Secrets in a vault; key rotation; IP allowlists; TLS 1.2+.
- Minimize PII; encrypt at rest; audit logs on access.
Retries & backoff
- Queue inbound webhooks; quick 200 ack; async processing.
- Exponential backoff with jitter; per‑event max_retries.
- Dead‑letter queue + replay admin UI.
Implementation phases
- Scope: confirm entities, volumes, SLAs; align on field ownership.
- Pilot: vehicles → trips; demo end‑to‑end order→arrival→proof.
- Harden: retries, idempotency, monitoring, dashboards.
- Rollout: migrate IDs, freeze schemas, train users, playbooks.
Sample webhook signature (HMAC)
POST /webhooks/telematics HTTP/1.1
X-Signature: t=1698570000,s=sha256=ab12…
Idempotency-Key: 2c1f3b76-…
Content-Type: application/json
{“event”:”trip.status.changed”,”id”:”evt_123″,”data”:{“trip_id”:”T-9001″,”status”:”arrived”,”site_id”:”CUST-77″,”ts”:”2025-10-29T14:01:00Z”}}
💬 FAQs
Should we build ETL or event‑driven?
Events for operational updates; ETL for analytics/backfill. Hybrid is typical.
How do we keep IDs in sync?
Mapping table with both external IDs; unique indexes; soft‑delete.
What about ERP rate limits?
Batch writes; queues; circuit breakers; per‑tenant throttles.
How do we test webhooks?
Record/replay staging events; inject clock skew; test retry/idempotency.
