OAuth Signature Issue in JIRA REST API

Using a JIRA REST client with OAuth produces a signature error. See the revised example:

<?php
namespace App\Services;

class JiraHandler {
    public function execute() {
        $settings = [
            'endpoint'    => getenv('JIRA_ENDPOINT'),
            'pem_file'    => __DIR__ . '/certs/jira_key.pem',
            'consumer_id' => getenv('API_CONSUMER_ID'),
            'consumer_key'=> getenv('API_CONSUMER_SECRET'),
            'callback'    => getenv('CALLBACK_URL')
        ];
        $connector = new JiraConnector($settings);
        return $connector->initiateAuth();
    }
}

In working on a similar project with OAuth and JIRA REST API, I encountered a signature error that ended up being related to your PEM file logistics. At one point, I found that the file path was correct but the file permissions were too restrictive, preventing proper reading of the key. I also had issues with inconsistent environment variable values between my local development and production environments. For me, a thorough check of file permissions and settings values was essential in resolving the error. I recommend verifying these details carefully as even minor oversights can lead to signature mismatches.

During a similar troubleshooting phase, I discovered that subtle differences in the device’s clock settings could result in OAuth signature errors when working with JIRA REST API. After confirming that my PEM file path and file permissions were correct, I verified the timestamp and nonce values used. Additionally, I found that mismatches in the OAuth endpoints sometimes caused discrepancies in the signature generation process. Debug logging was crucial in identifying these issues, which led me to correct minor discrepancies in the request formulation. Ensuring consistent configurations across environments is key to avoiding such challenges.
