I understand the need is to stabilize a live legacy PHP app by tracing auth flow issues, resolving the 401 CRM API error, verifying header handling, and ensuring AWS Secrets Manager integration works correctly on EC2 without refactoring the codebase. Implementation Approach: • Trace request/auth middleware and public route access logic • Debug API calls, headers, and base path configuration • Validate Secrets Manager region/config in PHP SDK • Apply minimal patches, restart services, and verify responses Queries: • Framework used or fully custom PHP? • Access to server logs and AWS IAM role details? • Is staging available or production-only? I will share my portfolio on your first message. I’m confident about delivery after our first meeting. Kindest Regards,
