@accurateitsolutionorg/zvt-client

Unified TypeScript ZVT client for both Verifone and Clover terminals.

Install

npm install @accurateitsolutionorg/zvt-client

Quick Start

import { ZvtClient } from "@accurateitsolutionorg/zvt-client";

const client = new ZvtClient(
  {
    terminal: "clover", // "verifone" | "clover"
    host: "192.168.178.132",
    port: 25690, // Clover default; Verifone usually 20007
    password: "000000", // 6 digits if terminal requires password
    orderNo: "1234", // used by Verifone legacy payload mode
  },
  (entry) => console.log("[ZVT]", entry),
);

const auth = await client.authorize(100); // 100 cents = 1.00
console.log(auth);

Constructor

new ZvtClient({
  terminal: "verifone" | "clover",
  host: string,
  port: number,
  password?: string,
  orderNo?: string | number,
}, forwardLog?)

Methods

• register(opts?)
• status(opts?)
• authorize(amountCents, opts?)
• cancel()
• raw(hex)
• reconcileLast(opts?)
• clearCooldown()
• cooldownStatus()

Notes

• password validation: exactly 6 digits when required.
• Verifone:
  • supports orderNo/reference in legacy payload mode.
• Clover:
  • uses readiness probing + cooldown guard to avoid early retries after abort/cancel.
