Watch out for

WhatsApp Business Cloud has strict template approval requirements so pre-approve your reminder templates before deploying.
Excel row locking can cause conflicts if multiple instances run simultaneously, add a unique transaction ID to track updates.
API rate limits on WhatsApp can block high-volume sends, implement a delay between each message send.
Secure payment links must not be hardcoded in the template, generate them dynamically per user to prevent security leaks.
