JIRA API OAuth authentication failing with invalid signature

I’m trying to use JIRA’s REST API with OAuth but I’m running into trouble. The API keeps telling me the signature is invalid. Here’s what I’ve done so far:

I’m using a JIRA REST API client I found online. My code looks something like this:

class APIController extends Controller
{
    public function fetchData()
    {
        $settings = [
            'jira_url' => 'http://jiraserver.local',
            'key_file' => '/path/to/private.pem',
            'app_id' => 'my-jira-app',
            'app_secret' => 'topsecret123',
            'redirect_uri' => 'http://myapp.local/callback'
        ];

        $jira = new JiraConnector($settings);
        $jira->connect();

        // $ticket = $jira->getTicket('PRJ-123');
        return view('ticket_info', ['ticket' => $ticket]);
    }
}

But when I run this, JIRA responds with an error saying the signature is invalid. I’ve double-checked my settings and they seem correct. Any ideas what could be causing this? Is there something I’m missing in the OAuth setup?

I’ve dealt with JIRA OAuth headaches before, and it can be frustrating. One thing that’s not mentioned yet is checking your OAuth scopes. Make sure you’ve requested the correct permissions for the API endpoints you’re trying to access. Also, verify that your OAuth dance is complete - sometimes the token exchange process can fail silently.

Another potential issue is URL encoding. If any of your parameters contain special characters, they need to be properly encoded. I once spent hours debugging only to find out a ‘+’ in my app name was causing issues.

Lastly, try using a tool like Postman to test your OAuth flow outside your code. This can help isolate whether the problem is in your implementation or the JIRA configuration. Good luck, and don’t hesitate to dig into JIRA’s OAuth documentation if you’re still stuck.

hey mate, i had similar issues w/ jira oauth. check your server time - if it’s off, the signature mexes. also, double-check the key format (rsa vs hmac) and app permissions. hope that helps!

I encountered this issue before. Make sure your private key is in the correct format and hasn’t been corrupted. Also, verify that your app_id and app_secret match exactly what’s in JIRA’s application settings. If those check out, try regenerating your OAuth tokens. Sometimes they can expire or become invalid. Lastly, ensure you’re using HTTPS for the JIRA URL, as some versions require it for OAuth. If none of that works, JIRA’s logs might provide more detailed error information to pinpoint the problem.
