Indicate that parameterObject has dynamic enum ?

[IOR88]

I try to have a parameter, which enum values has to be requested from different endpoint. So I haven't found any way how I could do it in specification. I though about 2 ways or I indicate that enum is dynamic with additionalProperties or I use $ref as value for enum attribute but not sure if this will be with accordance to specification ?

https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#parameterObject

{
  "in": "query",
  "name": "name",
  "$ref" : "#/paths/enums/name",
  "schema": {
    "type": "object",
    "additionalProperties": {
       "dynamicEnum": "bool"
    },
    "enum": {"$ref" : "#/paths/enums/name"}
  }
}

Any thoughts ?

This is how Microsoft do it for PowerApps and Flow.

"x-ms-dynamic-values": {
    "operationId": "PopulateDropdown",
    "value-path": "name",
    "value-title": "properties/displayName",
    "value-collection": "value",
    "parameters": {
        "staticParameter": "<value>",
        "dynamicParameter": {
            "parameter": "<name of the parameter to be referenced>"
        }
    }
}

Hi @darrelmiller,

Thanks for advice. I was thinking about something similar, I mean I wanted to refer to resources existing already within schema. Have You raised any issue to take Microsoft solution into consideration and based on that create standard for specification ? For me the case is not rare so it should be included in specification ?
