Whatsapp

WhatsApp is a messaging application owned by Meta that enables text, voice, and video communication over the internet. It serves individuals, families, and businesses across the world, particularly in regions where SMS costs are high or internet-based alternatives are preferred. The platform uses end-to-end encryption by default for personal chats and calls, ensuring that messages can only be read by the sender and recipient. Beyond personal use, WhatsApp Business offers tools for small and large enterprises to communicate with customers, share catalogs, and automate responses through APIs. The service supports group chats, file sharing, status updates, and voice/video calling, functioning as a primary communication tool in many countries outside the United States.
