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