Integrate vehicle history reports from Carfax or AutoCheck in a dealer-gated workflow

Steps

1. Both Carfax and AutoCheck (Experian) require a commercial agreement for API access; contact each vendor's partner/developer team to initiate the process — there is no self-serve sign-up for report access
2. Once contracted, receive credentials and access to the vendor's integration documentation; both providers typically offer a VIN-based lookup endpoint that returns report availability and a URL or embedded report
3. Implement a VIN lookup call: supply the VIN and your dealer/partner credentials; the response indicates whether a report exists and returns either a report URL, an embed token, or a structured data summary depending on the integration tier
4. For display integrations, use the vendor-provided iframe or redirect URL to show the report — reconstructing or scraping report content violates the terms of service; the vendor's UI must be used
5. Track report pulls against your contractual volume allotment; both providers bill per report pull, so implement checks to avoid pulling reports for the same VIN repeatedly within a session
