# Welcome to 1msg.io knowledge base!

Detailed information about the 1msg service.

This is the knowledge base of 1msg.io service. Here, information and instructions on the service's products will be collected.

The menu will help you navigate through the knowledge base, and here is a brief description:

[Onboarding](/docs/onboarding/attaching-your-whatsapp-number-to-waba-detailed-guide.md) - This section covers the process of connecting your number to WABA.

[WABA Coexistence](/docs/onboarding/attaching-your-whatsapp-number-to-waba-detailed-guide/waba-coexistence.md) - connect a number to WhatsApp Cloud API even if it is already linked to the WhatsApp Business app.

[SDK](/docs/api-1msg/ai-and-developer-tools.md) - ready-made code you add to your own app to use the WhatsApp Business API, without writing the requests yourself. TypeScript, Python, Java, Kotlin, Scala, C#, Ruby, Rust, Go, Swift, PHP, and C++. PHP and C++ are on GitHub only for now.

[MCP](https://github.com/1msg/1msg-mcp) - connects an AI assistant in your editor or chat to the 1MSG API, so it can call the API for you. Works in Cursor, Claude, and Codex, with 62 actions. Use the version hosted by 1MSG, or run it on your computer.

[CLI](https://github.com/1msg/1msg-cli) - the same API actions as a command you run in the terminal. Useful in scripts and on a schedule, when you already know which command to run. You do not need an AI assistant for this.

[Skills](https://github.com/1msg/1msg-for-agents) - a guide your AI assistant follows when it builds a 1MSG integration. It covers which tool to choose, how to confirm a message was sent, how webhooks receive replies, and what to check if a message does not arrive. The exact request format is in the API docs.

[WhatsApp Flow ](/docs/api-1msg/whatsapp-flow.md) - add an interactive multi-step form within WhatsApp chat that allows users to perform actions without navigating to an external website.

[Template analytics](/docs/api-1msg/template-analytics.md) - track campaign performance, monitor message quality, and optimize costs. The system provides data on delivery, reads, and button interactions.

[Green Badge](/docs/onboarding/obtaining-the-green-checkmark-badge.md) - Obtaining a new status for your business.
