About Surge

Through Operate As, your agent, n8n workflow or code works in Surge with your client's own access. Your client pastes their API key from Surge once. We store it encrypted, so it never sits in an email or a shared doc. It comes with 41 ready-made tools for Surge's API, and the request tool reaches any endpoint they don't cover.

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
