API-Supp

Connect WhatsApp numbers to your code, ChatGPT, or Claude by scanning a QR code. Key features: • Link a WhatsApp or WhatsApp Business number by scanning a QR code • Send text, images, video, and files through a simple HTTP API • Create polls, lists, and tap-to-reply buttons • Receive signed webhooks for incoming messages, deliveries, and reads • Look up chats, contacts, and message history • Add the cloud MCP server to ChatGPT, Claude, or Claude Code with one link • Run a local MCP server for files, voice notes, and media downloads The HTTP API lets developers send and receive messages from their own applications or from no-code tools such as n8n and Make. Each message returns a WhatsApp message ID, and delivery and read events arrive on your webhook, so you can track conversations as they happen. Media is uploaded once and can be reused across many chats. Several numbers can sit on one account, and the cloud MCP server gives an assistant access to every number at once. The cloud MCP option requires nothing to install. You paste a link, sign in, and your assistant can read and reply to messages on your numbers. The open-source local MCP server runs on your own computer for a single number and adds file handling, voice notes, and media download, working with Claude Desktop, Cursor, and Muse. Your number stays on your phone, so there is no device to host and no app to maintain. The service is a hosted backend and is not Meta's official Cloud API. Pricing is $7.50 per number per month. This tool suits developers building customer support bots, order notifications, and internal messaging tools, as well as operators who want their existing WhatsApp numbers available to chat assistants. Small businesses, agencies, and automation builders can connect several numbers under a single account and choose the access method that fits each project.
