Is there any example with GraphQL?

textQuery = "{ ""query"": ""{ loggedInAccount { id name slug }}"" }";
   
   httpConnection = New HTTPConnection("api.opencollective.com/graphql/v2", 443, ,,,60, New OpenSSLSecureConnection);
   
   httpRequest = New HTTPRequest;
   
   httpRequest.SetBodyFromString(textQuery, TextEncoding.UTF8);
   
   httpRequest.Headers.Insert("Content-Type",   "application/json");
   httpRequest.Headers.Insert("Api-Key",      api_key);
   
   httpResponse = httpConnection.Post(httpRequest);
   
   If httpResponse.StatusCode = 200 Then
      
      JSONReader = New JSONReader;
       JSONReader.SetString(httpResponse.GetBodyAsString());
       structureResponse = ReadJSON(JSONReader, False);
      
   EndIf;

Function Authentication() 
   Credentials = GetCredentials.WayFairCredentials();
   apiKey = Credentials.apiKey;
   apiSecret = Credentials.apiSecret;
   Data = New Structure;
   Data.Insert("grant_type","client_credentials");
   Data.Insert("client_id",apiKey);
   Data.Insert("client_secret",apiSecret);
   Data.Insert("audience","api.wayfair.com/");
   JSONWriter = New JSONWriter;   
   JSONWriter.SetString();   
   WriteJSON(JSONWriter, Data);
   result = JSONWriter.Close();
   
   //token = GetToken();
   
   Connection = New HTTPConnection("sso.auth.wayfair.com/oauth/token",,,,,,New OpenSSLSecureConnection());
   request = New HTTPRequest();
   request.SetBodyFromString(result);
   request.Headers.Insert("Content-type", "application/json");
   //  request.GetBodyAsString()
   HTTPAnswer = Connection.Post(request);
   res = HTTPAnswer.GetBodyAsString();
   
   jsonReader = New JSONReader;
   jsonReader.SetString(res);
   Dat = New Structure;
   Dat = ReadJSON(jsonReader);
   jsonReader.Close();
   
   return Dat;
