About CallHub

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

Common uses in Phone and SMS

  • Send appointment reminders and confirmations by text
  • Log calls and messages against the right customer
  • Follow up on missed calls
