About Finix

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

Common uses in Payments

  • Look up customers, payments and refunds
  • Send invoices and payment links
  • Report on revenue and failed payments
