Creating a rest endpoint for a Graphql banner

In this video, we demonstrate how you can convert a graphQL query into a REST endpoint.

  • Introduction
  • Creating the initial REST endpoint
  • Creating a Virtual Endpoint
  • Modifying headers

 

Example query:
https://countries.trevorblades.com/

{ 
  countries {
    name
    capital
    currency
  }
}

Virtual endpoint function:

function myTransformerFunction(request, session, config) {
  varresponseObject = {
  Body:"THIS IS A VIRTUAL RESPONSE",
  Code:200
}

  varresponse = transformationLogic(request)
  responseObject.Body = response.body
  returnTykJsResponse(responseObject, session.meta_data)
}

function transformationLogic(request){
  varrequestObj = JSON.stringify({
    "method":"POST",
    "domain":"https://countries.trevorblades.com/",
    "headers":{"content-type":"application/json"},
    "body":JSON.stringify({
      "query":"{countries{name, capital, currency}}"
    })
  })

  varresponseObj = TykMakeHttpRequest(requestObj)
  returnJSON.parse(responseObj)
}
