ERP and DMS integration: connecting your tools to vehicle data

ERPs (Enterprise Resource Planning) and DMS (Dealer Management Systems) are at the core of automotive professional operations. Whether managing vehicle stock, producing invoices or tracking repair orders, these systems need reliable, up-to-date vehicle data. Integrating a vehicle data API into these tools eliminates manual entry and its associated errors.

Pain points without an API

• Time-consuming manual entry -- each vehicle entering the DMS requires dozens of fields: make, model, version, engine, fiscal horsepower, colour, equipment
• Input errors -- mistakes on trim, engine or power are common and propagate throughout the system (quotes, invoices, declarations)
• Outdated data -- vehicle reference databases built into DMS platforms are not always current, especially for recent models
• Inconsistent formats -- each data source has its own format, making imports complex and fragile

Integration patterns

Direct integration (API call)

The simplest pattern: the DMS or ERP calls the AutomotivAPI API directly when a user enters a VIN or plate. The JSON response is mapped to the target system's fields. This pattern suits modern DMS platforms with an HTTP integration layer.

Middleware / ETL

For legacy systems that do not support native API calls, middleware bridges the gap between the AutomotivAPI API and the DMS. The middleware can be a lightweight service (Node.js, Python) or an integration platform like Zapier, Make or n8n. It receives events from the DMS (vehicle record creation), calls the API and injects data in the correct format.

Batch import

Some workflows require enriching a large volume of vehicles in a single operation. Batch import involves sending a list of VINs to the API and receiving enriched data in a structured file (CSV, JSON). This pattern is useful for data migration or periodic fleet updates.

Data mapping

The AutomotivAPI API returns data in a normalised JSON schema. Mapping to DMS or ERP fields is generally straightforward:

• brand → Make field in the DMS
• model → Model field
• trim → Version / Trim field
• engine.fuel → Fuel type field
• engine.power_hp → Power (DIN) field
• specs.co2_wltp → CO2 emissions field
• fiscal_power → Fiscal horsepower field

Non-standard or DMS-specific fields (internal codes, manufacturer references) can be derived from API data via lookup tables.

Compatible DMS examples

The standard AutomotivAPI REST API is compatible with any system capable of making HTTP requests. The most common DMS platforms in the French automotive sector all provide extension mechanisms or plugins for this integration:

• Dealership DMS (Sage, I'Car, DCSNet, Datafirst)
• General ERPs (SAP, Microsoft Dynamics, Odoo)
• Fleet management solutions (Athlon, ALD, Arval)
• Automotive CRMs (Salesforce, HubSpot with custom connectors)

Security and performance

Integration into an ERP or DMS involves specific security and performance requirements. The AutomotivAPI API meets these with:

• HTTPS encrypted communication
• API key authentication with optional IP restriction
• Response time under 300ms for 99% of requests
• Uptime exceeding 99.9%
