Whapi.Cloud is a REST API for WhatsApp automation โ€” no Meta approval, no business verification, no message templates required. Connect your number via QR code or OTP in minutes and start automating immediately.

What you can build: Send and receive text, media, files, reactions, and polls. Work with groups, WhatsApp Channels, and Statuses โ€” capabilities that official WABA solutions restrict or block entirely. Build chatbots, notification systems, CRM integrations, or any custom WhatsApp workflow.

Built for developers: Full JSON REST API with interactive Swagger docs and live request examples. Ready-to-run bot templates available in Python, PHP, Node.js, Java, C#, and Go โ€” clone, add your token, and run in minutes. No-code integrations for Make, n8n, and Pabbly Connect are also supported, along with MCP for AI agent workflows.

Stable by design: Whapi.Cloud connects via WebSockets โ€” not browser emulation โ€” so the service stays stable when WhatsApp updates its web interface, unlike competitors relying on DOM-scraping sessions.

Free lifetime sandbox: Every account includes a permanent free sandbox channel. No credit card. No expiration. Test and prototype before going live.

Simple, transparent pricing: Pay per channel. Unlimited messages and API calls included. No hidden fees, no per-message billing. Partner program available for agencies managing multiple client accounts.

Questions & Answers

As answered by people managing Whapi.Cloud and CheckNumber.AI.

Which are the primary technologies used for building your product?

Whapi.Cloud's answer

  • REST API over HTTPS with JSON โ€” the core integration method. All endpoints are documented in an interactive Swagger environment with live request examples, making it easy to explore and test the API directly from the browser.
  • Webhooks for event-driven architecture โ€” incoming messages, status updates, and other WhatsApp events are delivered to your server in real time via webhooks, enabling reactive, event-based application design.
  • Official code examples and ready-to-run bot templates โ€” available in Python, PHP, Node.js, Java, C#, and Go on GitHub. Designed to be cloned, configured with a token, and launched immediately โ€” reducing integration time to minutes.
  • No-code and low-code integrations โ€” native support for Make (Integromat), n8n, and Pabbly Connect, enabling WhatsApp automation without writing backend code.
  • MCP (Model Context Protocol) โ€” for teams building AI agents and LLM-powered applications, Whapi.Cloud supports MCP, allowing AI models to interact with WhatsApp directly as a tool.
  • WebSocket-based connection on the infrastructure side โ€” unlike competitors that emulate a browser session, Whapi.Cloud connects to WhatsApp via WebSockets, providing a more stable and resilient foundation that is not affected by WhatsApp web UI changes.

What makes your product unique?

Whapi.Cloud's answer

  • Developer-friendly API with a familiar REST structure โ€” clean documentation, code examples in Python, PHP, Node.js, Java, C#, and Go, and ready-to-run bot templates. A free lifetime sandbox is included for every account โ€” no credit card, no time limit โ€” so you can test and prototype safely before going live.
  • Cost-effective and technically robust WhatsApp automation โ€” built on socket-based architecture (not browser emulation), ensuring stable, resilient connections that are not affected by WhatsApp UI changes. Unlimited messages and API calls are included on all paid plans, with no hidden fees.
  • No Meta approval, business verification, or message templates required โ€” connect via QR code or OTP in minutes and send free-form messages immediately, including to groups, statuses, and channels โ€” capabilities that official WABA solutions simply do not offer.
  • Broad and continuously growing API feature set โ€” send text, media, files, reactions, and polls; manage groups and WhatsApp Channels; automate Stories/Statuses. New capabilities are shipped regularly, with AI-agent integration (MCP) already supported.
  • Reliable, developer-focused technical support โ€” available on every plan, including the free sandbox. Real assistance for real integration scenarios, helping you resolve issues efficiently during development and at scale.

How would you describe the primary audience of your product?

Whapi.Cloud's answer

  • Developers and technical teams building WhatsApp bots, automation workflows, or integrating WhatsApp into existing products โ€” CRMs, helpdesks, notification systems. They need a reliable API with clean documentation, multi-language code examples, and a sandbox to develop and test without time pressure.
  • SaaS founders and product teams creating software that includes WhatsApp as a communication channel โ€” chatbots, customer engagement tools, or notification services. Whapi.Cloud provides the infrastructure layer so they can focus on their product, not on maintaining a WhatsApp connection.
  • Agencies and integrators delivering WhatsApp automation solutions to multiple clients. The partner program, per-channel pricing model, and channel management via API make it practical to operate at scale across many accounts.
  • Businesses that need full WhatsApp functionality โ€” including groups, statuses, channels, and free-form messaging โ€” without going through Meta's WABA verification process, template approval, or per-message billing.
  • No-code and low-code builders connecting WhatsApp to their workflows via Make, n8n, or Pabbly Connect โ€” without writing backend code.
  • AI and chatbot developers integrating WhatsApp as an input/output channel for AI agents, including via MCP (Model Context Protocol) support.

Why should a person choose your product over its competitors?

Whapi.Cloud's answer

  • Transparent, predictable pricing โ€” pay per channel, not per message. One flat monthly fee per connected number includes unlimited messages and API calls, with no hidden costs. Unlike WABA (Meta), there is no per-message billing, no country-based rate tables, and no mandatory business verification.
  • More capable than official WhatsApp Business API. Whapi.Cloud supports groups, statuses, WhatsApp Channels, free-form messaging, and media โ€” features that Meta's WABA restricts or blocks entirely. You get full WhatsApp functionality without template approval workflows.
  • More stable than browser-emulation competitors. Whapi.Cloud connects via WebSockets โ€” the same protocol WhatsApp itself uses โ€” rather than simulating a browser session. This means the service is not disrupted when WhatsApp updates its web interface, unlike many competitors.
  • Fastest path from registration to working integration. Swagger docs, multi-language code examples (Python, PHP, Node.js, Java, C#, Go), ready-to-run GitHub bot templates, and no-code connectors (Make, n8n, MCP) โ€” plus a free lifetime sandbox to develop and test without any time pressure.
  • Technical support included at every tier, including free. Real developer-focused assistance, not just documentation links โ€” available during integration, at scale, and when issues arise in production.

Who are some of the biggest customers of your product?

Whapi.Cloud's answer

Whapi.Cloud serves thousands of developers and businesses across 100+ countries โ€” from independent developers building their first WhatsApp bot to agencies managing hundreds of client channels and SaaS companies that have integrated WhatsApp as a core communication layer into their products. Partner accounts with 500+ active channels are not uncommon on the platform.
