About Holded

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

Common uses in Accounting
