Error while requesting access and refresh token (404)




I’m writing a small java script which will get some reports about email campaigns.

I have a problem when I want to get an access and refresh token using a code (obtained from

I’m setting a HTTP Post to url
using the params

  • grant_type
  • client_id
  • client_secret
  • redirect_uri
  • code

I get following error:

An error occurred while processing your request.
Reference #25.67d81002.1504592913.1b080d23

This is the simplified java code I’m using to reproduce this error:

public class Test {

    private static final String BASE_URL = "";

    public static void main(String[] args) throws IOException {
        String code = "abcdef12-3456-7890-abcd-ef1234567890";
        String clientID = "abcdef12-3456-7890-abcd-ef1234567890";
        String clientSecret = "abcdef12-3456-7890-abcd-ef1234567890";
        String url = BASE_URL + "oauth/v1/token/";

        HttpClient client = HttpClients.createDefault();
        HttpPost post = new HttpPost(url);

        List<NameValuePair> urlParameters = new ArrayList<NameValuePair>(5);
        urlParameters.add(new BasicNameValuePair("grant_type", "authorization_code"));
        urlParameters.add(new BasicNameValuePair("client_id", clientID));
        urlParameters.add(new BasicNameValuePair("client_secret", clientSecret));
        urlParameters.add(new BasicNameValuePair("redirect_uri", ""));
        urlParameters.add(new BasicNameValuePair("code", code));
        post.setEntity(new UrlEncodedFormEntity(urlParameters));

        System.out.println("post: " + post);
        HttpEntity entity = post.getEntity();
        InputStream content = entity.getContent();

        BufferedReader postReader = new BufferedReader(new InputStreamReader(content));
        StringBuffer str = new StringBuffer();
        String lineStr;

        while ((lineStr = postReader.readLine()) != null){


        HttpResponse response = client.execute(post);
        System.out.println("\nSending 'POST' request to URL : " + url);
        System.out.println("Post parameters : " + post.getEntity());
        System.out.println("Response Code : " + response.getStatusLine().getStatusCode());
        BufferedReader responseReader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuilder result = new StringBuilder();
        String line;

        while ((line = responseReader.readLine()) != null) {


Unfortunately I cannot find any help for error handling in the documentation, so I want to ask if someone of you can help me.



@Felix Can you post the response from the HubSpot server?

(edit)Actually are you posting to API.hubspot… or APP.hubspot… you might have entered in the wrong url.


Hello pmanca,

yes it was this one character in my code what is wrong. I didn’t realize this in the long request.

With the url

it works perfectly.

Thank you :smiley:
