How to access passed Enum argument in Swift 3

Question

I'm having some trouble accessing a parameter that is passed with an enum.

Generic RequestType, more will be included.

enum RequestType {
  case flagging(api : FlaggingRequestType)
}

Here is my enum that accepts another FlaggingRequestType (another enum that accepts a string parameter)

enum FlaggingRequestType {
  case getFlag(api : String)
}

protocol Requestable {
  var requestType : RequestType { get set }
}

Here I build my flagging request

let flaggingRequest = RequestBuilder.buildFlaggingRequest(flagRequest: .getFlag(api: "http://www.apiworld.com"))

Here is my method to actually sends the request from another method.

func sendRequest(for apiRequest : Requestable) {
  switch apiRequest.requestType {
  case .flagging:
  self.flaggingAPI(for: apiRequest)
 }
}

The problem is I can't figure out how to access the value passed in the api parameter found in apiRequest/ flaggingRequest. Is this possible? I hope this is clear :)

Here's a great link for enums with associated values https://appventure.me/2015/10/17/advanced-practical-enum-examples/#sec-1-5

func sendRequest(for apiRequest : Requestable) {
    switch apiRequest.requestType {
    case .flagging(let api):
        // access api value here
        self.flaggingAPI(for: apiRequest)
    }
}
