Re: How to call webservice with body parameters in power bi?

I am able to hit the webservice url

but getting invalid parameters with zero results.

let
    url = "https://url",
    body = "{
	""query"":[
{
	""EMP_ID"": ""if"",
	""userName"":""name"",
	""lastAccessedDateTime"":""2016-10-18T07:10:40.000Z"",
        ""deviceId"":""id"",
   	""appKey"":""key"",
	""tokenid"":""kkshdsfif"",
        ""appType"":""web""
}
]
}",
    Source = Json.Document(Web.Contents(url,[
             Headers = [#"ContentType"="application/json"]
         Content = Text.ToBinary(body) 
             ]
