Response status code doesn't indicate success: 401 (unauthorized)

Amol Tidke 1

Hi All,

I am getting above error "Response status code doesn't indicate success: 401 (unauthorized)"
in response when I make an http call to my azure function from console app.

I have checked all the app service settings parameters, get function URL, CORS setting and everything is fine but still I am getting above error.

My function works fine on local but when I try to run as remote it fails. Its making call to Azure function but getting unauthorized in response.

Please find below screen shots:

The default authorization scope for generated functions is Function which requires a key to trigger when running on Azure. Locally, this is bypassed.

You can obtain the keys from the portal or via API as mentioned in the docs.

Hi Pramod,

Thank you for the reply but I am already passing the function URL in http call as below(passing two parameters url and file):

HttpResponseMessage responsePostMethod = ClientPostRequest("api/functionName?code=xyz", file);

private static HttpResponseMessage ClientPostRequest(string RequestURI, FileData file)
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("https://functionName.azurewebsites.net/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = client.PostAsJsonAsync(RequestURI, file).Result;
return response;
}

And here in response getting the above error:
Response status code doesn't indicate success: 401 (unauthorized)

Please help to resolve this issue.

Thnaks,

Could you confirm if you are using the right key based on the authorization scope? Function vs Host? Also, could you try setting it to Anonymous to rule out other factors in play?

Another scenario could be if you have authentication/authorization setup on your function app. Could you confirm?
