/1 being appended to api url

[Doug Murphy]

I am using RestSharp to make a call to eBay to retireive a oauth user token. When I make the call using Postman it works. In VB.Net I re-created the call using the latest version of RestSharp. When I monitor the call from the VB app using Fiddler I see that the endpoint being used is "POST https://api.sandbox.ebay.com/identity/v1/oauth2/token/1". It should be "POST https://api.sandbox.ebay.com/identity/v1/oauth2/token". The vb call returns 404 Not Found. 

Any idea why the RestSharp call is appending "/1" to the url?

RestSharp doesn't add anything to the request URL unless you tell it to. As you haven't posted your code, it's impossible to say what's wrong.

I wouldn't think it would add anything to the target url. Probably something I am doing but I can't see it. Here is the code I am testing with. I pretty much took it from Postman with some updates to work with the new version of RestSharp. Any suggestions would be appreciated. The code (sCode) I pass into the routine comes from eBay after the user authorizes issuing a user token. This routine should return the user token and a refresh token.

Async Sub RSGetCode(sCode As String)
        Dim client As RestClient = New RestClient("https://api.sandbox.ebay.com/identity/v1/oauth2/token")
        Dim request As RestRequest = New RestRequest(Method.Post)
        sCode = WebUtility.UrlDecode(sCode)
        With request
            .AddHeader("Content-Type", "application/x-www-form-urlencoded")
            .AddHeader("Authorization", "Basic TXVycGh5c0MtNzYxNy00ZGRmLTk5N2ItOD..........................")
            .AddParameter("grant_type", "authorization_code")
            .AddParameter("code", sCode)
            .AddParameter("redirect_uri", "Murphys_Creativ-Mu...........")
            .AddParameter("Scope", "https://api.ebay.com/oauth/api_scope/sell.inventory")

        End With
        Dim responce = Await client.PostAsync(request)
        'Dim responce = Await client.ExecuteAsync(request)
        Dim sR As String = responce.Content

    End Sub

Try making a call to a requestbin. I have no idea, I am sure RestSharp doesn't manipulate the URI unless it's told to do so by using path parameters.
