About Sezzle

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

Common uses in Payments

  • Look up customers, payments and refunds
