FitmentCore Wheel fitment API
Integration workflow

A practical route from your catalog to API integration.

An HTTPS JSON API that connects to your backend. Start with the vehicles and wheel workflows that matter to your business.

1. Define the workflow and review coverage

Tell us whether customers start with a car, a wheel or a complete set. Include the makes, generations, year ranges, product fields and expected request volume you need.

2. Agree company access

Our team creates the company account and configures access status, shared minute/day quotas and key IP allowances. Save the key securely: the full value is shown once on issuance.

3. Build the selector and map results

Fetch the vehicle catalog, use the returned slugs for fitment requests, and map the response to your stock. Width-specific ET ranges and complete staggered pairs are important when applying compatibility rules.

4. Test, monitor and maintain

Test representative vehicles, mixed diameters and axle bores. Handle 400/403/404/429 responses deliberately, respect Retry-After, and review corrections that affect cached results.
