Important notes
- Always
whatsapp_connect before calling any other tool. - Use
whatsapp_check_whatsapp to verify a phone number has WhatsApp before sending. - For broadcasts, add delays between messages to avoid rate limiting.
- File uploads use base64 encoding. Max file size: 100 MB.
- Poll options must be unique, 2–12 items, max 100 chars each.
- Message quoting only works within the same chat.
