I got this error using restsharp when trying to consume an API in Swagger
I need to use an API from Swagger that sends email but I am having a problem in authorization I passed the token but still the result is Unauthorized. I use the code below. Dim url = "test123/test.com/" (can't include the actual) Dim apiKey = "12312" Dim apiPassword = "12312" Dim client = New RestClient(url) Dim request = New RestRequest("token", Method.POST) request.Parameters.Clear() request.AddParameter("grant_type", "password") request.AddParameter("username", apiKey) request.AddParameter("password", apiPassword) Dim response As IRestResponse = client.Execute(request) _pristrKey = response.Content Return JsonConvert.DeserializeObject(response.Content) the content that i recieve is the Token from swagger but when i try to use it Dim url = "test123/test.com/" Dim client = New RestClient(url) Dim request = New RestRequest("api/email", Method.POST) request.Parameters.Clear() request.AddHeader("accept", "application/json") request.AddParameter("Authorization", String.Format($"Bearer " + _pristrKey), ParameterType.HttpHeader) request.AddHeader("Content-Type", "application/json") Dim apiInput = New With {Key .bulkId = "123", Key .from = "test123@gmail.com", Key .subject = "Test", Key .text = "Test123", Key .to = "test321@gmail.com"} request.AddParameter("application/json", JsonConvert.SerializeObject(apiInput), ParameterType.RequestBody) request.RequestFormat = DataFormat.Json Dim response As IRestResponse = client.Execute(request) I got this error in Header.{WWW-Authenticate=Bearer error="invalid_token"} And recieve this:response = "StatusCode: Unauthorized, Content-Type: , Content-Length: 0)"
