About Payhawk

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

Common uses in Accounting

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