About Nium

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