About Reachinbox

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