Levam OEM API

Levam OEM API is a REST API for original (OEM) auto parts catalogs. The API provides:

• the list of OEM catalogs (brands) and vehicle models;
• vehicle identification by VIN or by parameters (family, model, year, market, etc.);
• unit groups, parts, and diagrams with part coordinates;
• part applicability (which vehicles and units contain a given part number);
• order validation (do part numbers fit a VIN) and maintenance parts.

Base URL

https://api.levam.net

All methods are called with GET requests to paths of the form /oem/v1/{Method} and return JSON (UTF-8).

Quick start

curl "https://api.levam.net/oem/v1/CatalogsListGet?api_key=YOUR_KEY"

The API key is issued in your dashboard after registration. See Authentication.

Conventions

• api_key — required in every method.
• lang — optional response language (e.g. en, de, ru). If data is unavailable in the requested language, English is returned. Defaults to en.
• ssd (Server Side Data) — vehicle-selection session identifier. Returned by vehicle selection methods; pass it to the next method in the chain. See vehicle selection.
• Every successful response contains an error field; an empty string means no error. See Error codes.

Typical call chain
