RedotMPP

RedotMPP is a small helper for RedotPay Connect OpenAPI signing.

It provides:

• redot.createHeaders({ path, body }) (RSA signature + timestamp headers)
• RedotMPP.defaults.* helpers for parsing/normalizing OpenAPI responses

Install

npm i @redotpay/mpp mppx

Usage

Create the client:

import { RedotMPP } from '@redotpay/mpp/server'

const redot = new RedotMPP({
  baseUrl: process.env.REDOTPAY_OPENAPI_BASE_URL!,
  auth: {
    appKey: process.env.REDOTPAY_OPENAPI_AK!,
    keyVersion: Number(process.env.REDOTPAY_OPENAPI_KEY_VERSION ?? '1'),
    privateKeyPath: process.env.REDOTPAY_OPENAPI_PRIVATE_KEY_PATH!,
  },
})

Create OpenAPI headers:

const headers = await redot.createHeaders({
  path: '/openapi/v2/order/detail',
  body: { orderSn: '...' },
})

Parse helpers:

• RedotMPP.defaults.parseData(json) returns json.data ?? json
• RedotMPP.defaults.isPaid(detail) tries common paid-status fields
• RedotMPP.defaults.getAmount(detail) / getCurrency(detail) normalize common fields
