Core concepts

Vehicles, lots and IDs

A vehicle is returned in data. Each vehicle can hold several auction records in lots, so keep the source and lot identity when you update your catalog.

ValueMeaning
data.idInternal vehicle ID.
lots[].idInternal lot-record ID.
lots[].lotSource lot number, used by the lot lookup.
lots[].external_idSource external vehicle ID. Use search_by_id=1 for this lookup mode.
vinStored vehicle identification number.
lots[].domain.idSource ID: 3 for Copart, 1 for IAAI.
{domain}Path value in the lot lookup: copart_com or iaai_com.

Filtering /cars selects vehicles that have a matching listing. The nested lots of a returned vehicle can include other records, so check each lot's source before you pick one to display.
