About Firma.dev

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