Hi all...can anyone please letme know how to integrate whatapp with Netsuite.Thanks in advance.

It depends on what you mean. If you're looking for yourself to host the whatssap server, I'd wish you good luck with that. That's the proper way which requires you to host on your own AWS account, and have the servers setup accordingly. Instead, I'd suggest looking for a whatssap authorized partner, like twilio. or equivalent.
