About Trestle
Through Operate As, your agent, n8n workflow or code works in Trestle with your client's own access. Your client pastes their API key from Trestle once. We store it encrypted, so it never sits in an email or a shared doc. Your agent reaches any endpoint of Trestle's API through the request tool, with the client's access attached.
