The result is `exact` with the value to store at `path`, `candidates` best first for the person to pick from, or `none`. It never picks between two. A choice's label, value or alias matches exactly; dates take written forms that parse one way, money and limits forms such as `100/300` or `100k`, a full VIN the part its contract keeps (`x-reduce`), checked by its check digit (`x-check`). Send `answers` when the question's answers depend on earlier ones, as a car's model does on its make. Needs access to rate every named version and your `raters:run` permission. Matching changes nothing, so the request is safe to repeat. ## OpenAPI ````yaml /openapi.json post /insurance/rating-programs/match openapi: 3.0.3 info: title: Effective API version: 2.0.0 description: The public Effective REST API.
