WordPress REST Sandbox Fix

My WordPress site relies on a third-party RESTful API for user authentication, but the calls succeed only in the live environment; every sandbox request fails and blocks further testing. The goal is to trace the exact misconfiguration, patch it, and leave the staging area fully functional again. You will: • Pinpoint why the current API integration breaks inside the sandbox (keys, endpoints, headers, or any WordPress-side hook/plugin conflict). • Apply the necessary code or settings change so test credentials authenticate correctly. • Document in a few clear sentences what you changed and why, so I can reproduce the fix on future builds. The stack is a standard LAMP WordPress install; I can provide cPanel, wp-admin, and temporary API keys as soon as we start. This should be a quick task for someone comfortable with WP, PHP, and REST debugging tools like Postman or wp_remote_request.
