I have created API token and recorded the value to use in the application. With that I can see all the group details in postman.

But the same is not working with my java application and getting 400 error.

```auto
String oktaURL = "https://oktaservername.oktapreview.com/api/v1/groups";
URL url1 = new URL(oktaURL);
httpsClient = (HttpsURLConnection) url1.openConnection();
httpsClient.setRequestMethod("GET");
httpsClient.setRequestProperty("Accept","application/json");	
httpsClient.setRequestProperty("Content-Type","application/json");	
httpsClient.setRequestProperty("Authorization", "SSWS xxxxxxxxxxx");
httpsClient.setInstanceFollowRedirects(false);

log.info ("Send the GET request");
// Send post request
httpsClient.setDoOutput(true);

```

Please shed some light with this issue.

I’m not very familiar with Java but what is the connection between `oktaUrl` and `url1`?

API call didn’t work for me unfortunately got 405/400 error. Using okta sdk solved the issue. There is a built in listGroups method helped.
