Getting 500 Internal Server Error in POST Request HttpClient

Khaja Moizuddin

I am getting 500 Internal Server error with endpoint POST request using HttpClient C# with the access token

HttpClient client = HeadersForCreateUser(accessToken);

HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, Uri.EscapeUriString(client.BaseAddress.ToString()));

request.Content = new StringContent(JsonBody, Encoding.UTF8, "application/json");

request.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");

HttpResponseMessage response1 = client.PostAsync(Uri.EscapeUriString(client.BaseAddress.ToString()), request.Content).Result;

private static HttpClient HeadersForCreateUser(string accessToken)

{

HttpClientHandler handler = new HttpClientHandler() { UseDefaultCredentials = false };

HttpClient client = new HttpClient(handler);

client.BaseAddress = new Uri(endpointURL);

client.DefaultRequestHeaders.Accept.Clear();

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

//client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));

client.DefaultRequestHeaders.Add("apikey", apikeyvalue);

client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);

//client.DefaultRequestHeaders.Add("Content-Type", "application/x-www-form-urlencoded");

return client;

}

Is anyone has faced this kind of issue, please give a reply.

First check your request using POSTMAN . IF you are getting resposne , then there is mistake from your code.
If you are not getting response, then 1. Request data is not as expected by server api or

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

Remove this line and check once.

Two different content type are used:1.application/x-www-form-urlencoded
2. application/json

Please check which content type is required for api.
Httpclient and HttpWebRequet are being used. Can't any one of them can be used?

Status 500 represents Internal Server Error. This means that your C# server-side code or the API that you trying to call throws an error. There's no quick way to fix the error without stepping into it. I would suggest you to debug your code to identify which line in your code generates the error.

Basically, 500 means internal server error. This is problem with the api. In the api it is generating some exception and due to this reason it raises 500 or Internal server error. So what you can do is check api code by debugging.
For 500 error message check below link that why it is generating error,
