Introduction

Get started with Bird

Email, SMS, and WhatsApp share one platform, with per-channel endpoints over common infrastructure. Create a key, send your first message, then wire up the rest at your own pace.

Pick a use-case quickstart to go from zero to your first send. Every quickstart provides one guided happy path and is the canonical destination for related channel and product pages.

Beyond the quickstarts, the documentation has five areas. The Guides explain how Bird works and cover each channel in depth, and the Knowledge base handles operational tasks. The SDKs provide typed API methods, the CLI works in terminals and agent loops, and the API reference documents every endpoint.
