C# rest api mail gun gives forbiden access status-CodePudding

Good day, I am trying now to do email vertification, and followed all instructions but i get response status Unauthorized

private bool SendEmail(string body, string email)
    {
        //create client
        RestClient client = new RestClient("https://api.eu.mailgun.net/v3");

        client.Authenticator =
            new HttpBasicAuthenticator("api",
            "02a4bca7b2e0c72e98841b20beef1585-69210cfc-a7bc0929");

        var request = new RestRequest();

        request.AddParameter("domain", "sandbox4706f89b4150439ebca3c380f3fa96d0.mailgun.org");
        request.Resource = "{domain}/messages";
        request.AddParameter("from", "Ecommerce sandbox Mail<[email protected]>");
        request.AddParameter("to", email);
        request.AddParameter("subject", "Email Vertfication Email");
        request.AddParameter("text", body);
        request.Method = Method.Post;

        var response = client.Execute(request);

        return response.IsSuccessful;

    }

Do anyone had the same problem? I am conecting from EU so changed rest Client from

So, base URL shouldn't be https://api.mailgun.net/v3/ but

Once you have correct base URL and authorized (and verified recipient), you can send your email. So, in your example, it would be like this (look at comments also):

//note the URL with domain
RestClient client = new RestClient("https://api.eu.mailgun.net/v3/sandbox4706f89b4150439ebca3c380f3fa96d0.mailgun.org");

client.Authenticator =
    new HttpBasicAuthenticator("api",
    "02a4bca7b2e0c72e98841b20beef1585-69210cfc-a7bc0929");

var request = new RestRequest();

//request.AddParameter("domain", ... is not needed anymore becasue of base URL
//also, Resource is now without {domain} parameter
request.Resource = "/messages";
request.AddParameter("from", "Ecommerce sandbox Mail<[email protected]>");
//this mail should be authorized recipient
request.AddParameter("to", email);
request.AddParameter("subject", "Email Vertfication Email");
request.AddParameter("text", body);
request.Method = Method.Post;

var response = client.Execute(request);

return response.IsSuccessful;

... And that should send the email without Unauthorized error
