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