Error with responseData

Hello, i receive this error:
“error”: “Authorization field/api_key missing in request. If you do not have a token, please sign up for one at

Api key is correct because i paste link generated from instruction i obtain correct response from browser as you can see:

what am I doing wrong?

Hi @Fabio7586,

your API key is still visible in the second URL.

You can try adding a Content-Type Header similar to the Accept header with
"Content-Type: application/json; charset=utf-8".
That might be the problem, but not quite sure as i’m not familiar with C#.

If you can get the request to work, would be great if you let us know how, so we can update the C# example of the Playground.

Best regards

No way, seems related to Authenticate so i decided to change apporoach: I followed example about posting json:
Quotas are ok; I checked result JSON format with online tool.

and it give me another error:

Someone can help me?

Thank you

Hmm that’s rather strange…
Maybe you have to set it directly in the request, else it might be derived from the content, which is a string…
try this:

As you suggested, i followed example:

result is:
[0:] Response: StatusCode: 405, ReasonPhrase: ‘Not Allowed’, Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

Any ideas?

Found a solution for GET:

var url = ",49.41461&end=8.687872,49.420318";

            var httpRequest = (HttpWebRequest)WebRequest.Create(url);

            httpRequest.Headers["Authorization"] = "Bearer your_api_key";

            var httpResponse = (HttpWebResponse)httpRequest.GetResponse();
            using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
                var result = streamReader.ReadToEnd();


I’m trying to test POST method with an online working tool. No way to work it give same error given by my app:

For the get request both api_key parameter and Authorization header can be used.
However, in the Header you don’t need Bearer, just Authorization: 5b3ce3.....

In your online tool, you don’t have th right path to the directions endpoint. It should be something like:
Please check the documentation for available ones.
You can try generating a curl request with the example code button, to see which the minimal Headers are that you nead for the request.

Ok, you are right: in the GET it doesn’t need Bearer; it work without it.
For the POST following code works very well:

 var url = "";

                var httpRequest = (HttpWebRequest)WebRequest.Create(url);
                httpRequest.Method = "POST";

                httpRequest.Accept = "application/json";
                httpRequest.Headers["Authorization"] = "Bearer 5b3ce3597851110001cf6xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
                httpRequest.ContentType = "application/json";

                var data = @"{""coordinates"":[[8.681495,49.41461],[8.686507,49.41943],[8.687872,49.420318]]}";

                using (var streamWriter = new StreamWriter(httpRequest.GetRequestStream()))

                var httpResponse = (HttpWebResponse)httpRequest.GetResponse();
                using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
                    var result = streamReader.ReadToEnd();


your example in the API Playground dont work (ok, in the online tool with correct uri, works) check screen with result error:

AH, I FORGOT to say that, i’m using Xamarin Forms that support only mono framework (yes in short will be support fully .net 6 and c#9) taht is similar to .net standard 2.

Here you go

using System;
using System.Text;
using System.Net.Http;
using System.Net.Http.Headers;
using Newtonsoft.Json;

var baseAddress = new Uri("");

using (var httpClient = new HttpClient{ BaseAddress = baseAddress })
  httpClient.DefaultRequestHeaders.TryAddWithoutValidation("accept", "application/json, application/geo+json, application/gpx+xml, img/png; charset=utf-8");
  httpClient.DefaultRequestHeaders.Authorization =
      new AuthenticationHeaderValue("Bearer", "xxx");
    // quotes might have to be escaped
    using (var content = new StringContent("{\"coordinates\":[[8.681495,49.41461],[8.686507,49.41943],[8.687872,49.420318]]}", Encoding.UTF8, "application/json"))
      using (var response = await httpClient.PostAsync("/v2/directions/driving-car", content))
        string responseData = await response.Content.ReadAsStringAsync();
        var data = JsonConvert.DeserializeObject(responseData);
		var serialised = JsonConvert.SerializeObject(data);

OMG It works. I’m sure that i have tested your solution and it gave me:
“error”: “Daily quota reached or API key unauthorized”
maybe i was worng in something…
Thank you for fully support you gave me!!!
