For applications that deal with auto loans, whether that’s auto refinancing, insurance, fleet management, or vehicle valuation, Method can enrich an Entity’s profile with detailed vehicle information.

​
How It Works

Vehicles is an Entity-level product: you request it against an Entity, not an individual Account. This means a single request returns all vehicles associated with that person. The response is synchronous, you’ll get the data back immediately. The vehicles array in the response contains one object per vehicle, each with:
  • vin: Vehicle Identification Number
  • year: Make year (e.g., “2021”)
  • make: Manufacturer (e.g., “honda”)
  • model: Model (e.g., “accord”)
  • series: Series/Trim/Category (e.g., “lx”, “ex”), may be null
  • major_color: Primary color (e.g., “black”)
  • style: Body style (e.g., “sedan/saloon”, “crew_pickup”, “sport_utility_vehicle”)
This transforms an abstract “auto loan” line item into a concrete vehicle identity. Instead of showing “Auto Loan: $18,450 balance,” your product can display “2022 Honda Civic LX: $18,450 remaining.” This enrichment dramatically improves the user experience and enables vehicle-specific features like valuation estimates, equity calculations, and insurance comparisons.

Multiple Vehicles

An Entity can have multiple vehicles. The response vehicles array will contain all of them. This is useful for presenting a vehicle selector in your UI or for fleet management use cases.
