Introduction

LingoHub manages the translations of your apps, websites and documents. Its APIs let you automate the work around them: send new source texts in, get finished translations out, and keep LingoHub in step with your code, your content and your release process.

Which API should I use?

New integrations should use API V2.

The LingoHub CLI (lingohub) calls API V2 from your terminal, scripts and AI agents. It's updated together with API V2, so use it where possible.
