Create a personalized car research session for the buyer. Returns a unique URL they can bookmark and return to.

cars_session_notify

Set the buyer's email notification preference for this session.

  }
}

cars_session_tradein

Set or update the buyer's trade-in vehicle information. Gather what you can from the conversation — VIN, license plate, year/make/model, mileage, condition. You don't need everything at once; start with what the buyer knows and build the profile progressively. The dealer will make the trade-in offer based on this info. Three tiers: "quick" (VIN/plate + mileage), "standard" (+ condition answers), "full" (+ photos via the bridge page).

Argument	Type	Description

    }
  }

cars_session_visit

Schedule a dealer visit (test drive, purchase, trade-in appraisal). Generates a visit code and QR code the buyer shows at the dealership. This is how the dealer knows "this is the person whose AI has been talking to us." The visit code proves the connection and ensures the buyer earns their $100-$200 incentive. Only use when the buyer explicitly says they want to visit the dealer.

Argument	Type	Description
vin*	string	VIN of the vehicle they want to see
date	string	Preferred date (e.g. "Saturday", "2026-05-10")
