About OnSync

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

Common uses in CRM and sales

  • Add new leads from forms, emails and calls
  • Move deals along and log activity after each conversation
  • Keep contact records clean and complete
