About Shift4

Through Operate As, your agent, n8n workflow or code works in Shift4 with your client's own access. Your client pastes their API key from Shift4 once. We store it encrypted, so it never sits in an email or a shared doc. Your agent reaches any endpoint of Shift4's API through the request tool, with the client's access attached.

Common uses in Payments

  • Look up customers, payments and refunds
