About Fire

Through Operate As, your agent, n8n workflow or code works in Fire with your client's own access. Your client pastes their API key from Fire once. We store it encrypted, so it never sits in an email or a shared doc. It comes with 37 ready-made tools for Fire's API, and the request tool reaches any endpoint they don't cover.

Common uses in Accounting

  • Create invoices and record payments
  • Match transactions and chase overdue bills
  • Pull numbers for a monthly report
