About Nexpay

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