About Billomat

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