Test 3: SimpleShareFileAPI Class Loading
========================================
✅ SimpleShareFileAPI.php loaded successfully
✅ SimpleShareFileAPI instantiated successfully

Analysis:
=========
If Test 1 works but Test 2 fails: There's a difference in the request format
If Test 2 works but Test 3 fails: There's an issue with the class implementation
If all tests fail: There's a fundamental authentication issue
If all tests pass: The issue might be elsewhere in the connector
