Watch out for

WhatsApp has strict rate limits on message sending so you must implement queuing to avoid temporary bans during high traffic.
Voice notes require transcription before analysis which adds latency so you should consider async processing for better user experience.
Large PDF files may exceed token or size limits in the OpenAI API so you need to add logic to truncate or summarize content first.
Audio responses must be encoded correctly as MP3 or OGG with proper headers otherwise the WhatsApp client will not play them.
