Experienced PHP cURL Expert Needed

I'm looking for a highly experienced PHP cURL expert to troubleshoot and resolve an issue with an HTTP request. The request works perfectly in Postman but fails to work when using PHP cURL. Please note that I do not own the server to which the request is being sent, so the solution must involve resolving the problem from the client-side.

Requirements:
Strong experience with PHP and cURL.
Proven expertise in troubleshooting and debugging HTTP requests.
Ability to analyze HTTP headers, payloads, and responses.
Familiarity with different request methods (GET, POST, etc.) and content types.
Knowledge of server-side behaviors, redirects, and security mechanisms.
Strong problem-solving skills to identify and resolve the issue.

Task:
Analyze the existing PHP cURL request and compare it with the Postman configuration.
Identify the discrepancies causing the request to fail in PHP.
Provide a working PHP cURL script that successfully mimics the Postman request.

Additional Information:
This task will be conducted remotely via AnyDesk, TeamViewer, or UltraViewer.
Immediate availability is preferred.
This is a one-time task but may lead to further collaboration if done well.

If you have the necessary expertise and experience, please reach out with your past relevant work and proposed solution approach.

Looking forward to your proposals!
