What does GREEN-API do?
GREEN-API is a WhatsApp messaging API that lets developers integrate WhatsApp into their apps, websites, or business systems. You can send and receive text, images, videos, documents, locations, and contacts through a reliable gateway. It's built for programmers who need programmatic control over WhatsApp, whether for customer support, notifications, or chatbot projects.
The API offers a wide range of functions: sending messages with buttons, creating and managing groups, posting statuses with delivery stats, polling contacts, and checking if a number has WhatsApp. It also includes a GPT integration that lets you build ChatGPT-powered chatbots. GREEN-API provides SDKs for many languages (Python, Node.js, Go, Java, C++, PHP, HTML, and 1C) and integrations with tools like Zapier, Make, Slack, and n8n. The free tier includes 3 chats and 100 number checks per month, which is enough to test and prototype.
This tool is best for developers and businesses that need to automate WhatsApp communication. You can use it to send bulk notifications, build conversational chatbots, connect WhatsApp to a CRM or ERP system, or create custom marketing workflows. If you need a straightforward way to add WhatsApp messaging to your software without reverse-engineering the protocol, GREEN-API does the heavy lifting.
