  • MapKey type: string
  • MapKey value: parameter name
  • MapValue type: If parameter's entity type is a composite entity then use map, otherwise, depending on the parameter value type, it could be one of string, number, boolean, null, list or map.
  • MapValue value: If parameter's entity type is a composite entity then use map from composite entity property names to property values, otherwise, use parameter value.
resolvedInput

string

Final text input which was matched during MatchIntent. This value can be different from original input sent in request because of spelling correction or other processing.
matchType

enum (MatchType)

Type of this Match.
confidence

number

The confidence of this match. Values range from 0.0 (completely uncertain) to 1.0 (completely certain).
