Getting 400 error while hitting groups endpoint

[angeline.alex]

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.

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.
