Project description:
"My existing WhatsApp bot is running on PHP 8.1 and I want the whole codebase moved to the latest stable PHP release while keeping every endpoint on the WhatsApp Cloud API fully functional. During the upgrade I also need proper error-logging introduced wherever something meaningful happens:

• message sending
• user authentication
• message templates

All log files should be human-readable, rotated daily, and stored outside the web root.

The template messages the bot used to send are still hard-coded in the source; after the upgrade they must work exactly as before without breaking namespace or signature checks at Meta’s end.

When the job is done I would like a brief walkthrough (screenshare or concise written notes) so I can clear up a few basic doubts about the new structure, how to add more templates, and where to look when logs flag an exception.

Deliverables
1. Updated, fully tested bot compatible with the latest PHP version ([login to view URL] included).
2. Robust logging layer covering the three areas listed above.
3. Restored “old” template messages sending successfully in production.
4. A short explanatory session or documentation pack answering my noted questions.

No new workflow changes are needed—just a clean, modernised codebase that behaves exactly as the current one but is easier to maintain and debug." (client-provided description)
