About Flat

Through Operate As, your agent, n8n workflow or code works in Flat with your client's own access. Your client pastes their API key from Flat once. We store it encrypted, so it never sits in an email or a shared doc. It comes with 81 ready-made tools for Flat's API, and the request tool reaches any endpoint they don't cover.
