OEM Parts Cross-Reference API
Enter any OEM part number and instantly find every compatible alternative from your own inventory. Built for retailers, dealerships, and e-commerce platforms that need accurate cross-reference matching at API speed.
How it works
Your customer or storefront sends an OEM number to the AutoWiz API. We resolve it against the manufacturer's original part, then match it against your own stock to return only the compatible parts you actually carry — no dead-end results pointing to inventory you don't have.
Why retailers use it
Instant cross-reference
Millisecond-speed matching means the API can power live search boxes, not just batch jobs.
Full documentation
A RESTful API with complete docs, so your engineers can scope integration without back-and-forth.
Matches your own stock
Results are always resolved against your inventory, so customers only see parts you can actually sell.
Live in 7 days
Get fully integrated with the AutoWiz API in about a week, not a quarter.
Frequently asked questions
What does the OEM Parts API return?+
Given an OEM part number, the API returns every part in your own inventory that is a verified compatible match, along with the identifying details you already store for that part.
How fast is a lookup?+
Cross-reference matching runs in milliseconds per request, so it can sit directly behind a live storefront or point-of-sale search box.
How long does integration take?+
AutoWiz is a RESTful API with full documentation. Most retailers, ERPs, and e-commerce platforms are fully integrated within 7 days.
Does it work with my existing inventory?+
Yes. Matches are resolved against your own stock, so results only ever surface parts you actually have available.
