Calling Kaizala(REST API) using RestSharp DLL

sunmorningindia · 2017-11-09

Hi,

For demo purpose I am trying to call Kaizala Rest APIs (https://docs.microsoft.com/en-us/Kaizala/).
I want to use RestSharp(http://restsharp.org/) DLL for this purpose. I tried with following code:

Variables
Client DotNet RestSharp.RestClient.'RestSharp, Version=106.0.1.0, Culture=neutral, PublicKeyToken=598062e77f915f75'
Request DotNet RestSharp.RestRequest.'RestSharp, Version=106.0.1.0, Culture=neutral, PublicKeyToken=598062e77f915f75'
Method DotNet RestSharp.Method.'RestSharp, Version=106.0.1.0, Culture=neutral, PublicKeyToken=598062e77f915f75'
ParameterType DotNet RestSharp.ParameterType.'RestSharp, Version=106.0.1.0, Culture=neutral, PublicKeyToken=598062e77f915f75'
Response DotNet RestSharp.RestResponse.'RestSharp, Version=106.0.1.0, Culture=neutral, PublicKeyToken=598062e77f915f75'

CAL Code
Client := Client.RestClient(STRSUBSTNO(GeneratePinURLTxt,ApiRoot));
Request := Request.RestRequest(Method.POST);
Request.AddHeader('postman-token', GetPostmanToken);
Request.AddHeader('cache-control', 'no-cache');
Request.AddHeader('content-type', 'application/json');
Request.AddParameter('application/json',GetGeneratePinParameter,ParameterType.RequestBody);
Response := Client.Execute(Request);
Compilation error for last line :

Microsoft Dynamics NAV Development Environment

The call is ambiguous between the following methods:'Execute(IRestRequest request)'and'Execute(IRestRequest request)'

OK

Thanks in advance.

This normally seems to be a constructor Issue and specially constructor with same number of parameters but different arguments.

Cross verify the Constructor that you are calling.

I tried with other version of RestSharp.DLL but no luck.

Unfortunately, C/AL is unable to identify the “Execute()” method’s overloads, which results in the known “The function call was ambiguous” error. To solve this, you could wrap it in a small custom .NET dll, which consists of the following couple of lines:

using RestSharp;

namespace Comsol
{
    public static class ApiHelper
    {
        public static IRestResponse ExecuteRestCall(ref RestClient restClient, ref RestRequest restRequest)
        {
            return restClient.Execute(restRequest);
        }
    }
}

Howdy, Stranger!
