AliExpress SDK

A simple, lightweight, and fully type-safe SDK for the AliExpress Open Platform APIs. Supports System Authentication, Dropshipping, and Affiliate APIs.

📖 Overview

AliExpress has completely migrated their services from the legacy Taobao Open Platform to the new Open Platform for International Developers. While this update brought significant improvements, they have yet to release an official Node.js SDK for the new platform.

This unofficial SDK bridges that gap by providing a simple, consistent interface for Node.js developers to interact with AliExpress APIs.

✨ Features

This SDK provides several key capabilities:

🔐 Authentication & Security

• Request Signing - Automatic generation of method signatures required by AliExpress
• Session Management - Streamlined token generation and refresh flows
• Error Handling - Consistent error responses with detailed messages

💻 Developer Experience

• Type Safety - Fully typed parameters and responses for all API methods
• Intuitive API - Clean, method-based approach to API calls

🛍️ Supported APIs

• System Authentication - Token generation, refresh, and security token operations
• Dropshipping API - Product details, order management, shipping calculations, and more
• Affiliate API - Product discovery, link generation, commission tracking, and reporting

📦 Installation

# Using npm
npm install ae_sdk

# Using pnpm
pnpm add ae_sdk

# Using yarn
yarn add ae_sdk

🚀 Getting Started

Prerequisites

Before using this SDK, you'll need to complete several steps on the AliExpress Open Platform:

1. Register as a Developer

   • Create or use an existing AliExpress account
   • Register as a developer at AliExpress Open Platform
   • Detailed registration guide

2. Create an Application

   • Register a new application on the platform
   • Application registration guide

3. Get API Credentials

   • Retrieve your app_key and app_secret from your registered application
   • Credential retrieval guide

4. Obtain Access Token

   • Guide users through the authorization flow to get an access token
   • Authorization flow guide

Basic Usage

1. Initialize a Client

Choose the appropriate client based on your needs (System, Dropshipper, or Affiliate):

import { DropshipperClient } from "ae_sdk";

const client = new DropshipperClient({
  app_key: "YOUR_APP_KEY",
  app_secret: "YOUR_APP_SECRET",
  session: "ACCESS_TOKEN_FROM_AUTH_FLOW",
});

2. Make API Calls

Each client provides typed methods for different API operations:

// Get product details
const productResponse = await client.productDetails({
  product_id: 1005004043442825,
  ship_to_country: "US",
  target_currency: "USD",
  target_language: "en",
});

if (productResponse.ok) {
  console.log("Product:", productResponse.data);
}

3. Handle Responses

All API methods return a consistent response structure:

// Successful response
{
  ok: true,
  data: {
    // API-specific response data
    aliexpress_ds_product_get_response: {
      result: { /* product data */ },
      rsp_code: 200,
      rsp_msg: "Call succeeds",
      request_id: "1234567890"
    }
  }
}

// Error response
{
  ok: false,
  message: "Error message explaining what went wrong",
  request_id: "1234567890", // If available
  error_response: {}, // Full AliExpress error response if available
  error: {} // JavaScript Error object if applicable
}

📚 API Examples

System Client

For authentication and token management:

import { AESystemClient } from "ae_sdk";

const systemClient = new AESystemClient({
  app_key: "YOUR_APP_KEY",
  app_secret: "YOUR_APP_SECRET",
  session: "EXISTING_ACCESS_TOKEN", // Optional for some operations
});

// Generate a new token from an authorization code
const tokenResponse = await systemClient.generateToken({
  code: "AUTH_CODE_FROM_REDIRECT",
  uuid: "OPTIONAL_UUID",
});

// Refresh an existing token before it expires
const refreshResponse = await systemClient.refreshToken({
  refresh_token: "REFRESH_TOKEN_FROM_PREVIOUS_AUTH",
});

Affiliate Client

For affiliate marketing operations:

import { AffiliateClient } from "ae_sdk";

const affiliateClient = new AffiliateClient({
  app_key: "YOUR_APP_KEY",
  app_secret: "YOUR_APP_SECRET",
  session: "ACCESS_TOKEN",
});

// Generate affiliate tracking links
const linksResponse = await affiliateClient.generateAffiliateLinks({
  promotion_link_type: 0, // 0 for normal, 2 for hot product link
  source_values: "https://www.aliexpress.com/item/1234567890.html",
  tracking_id: "YOUR_TRACKING_ID",
  app_signature: "YOUR_APP_SIGNATURE",
});

// Find trending products with high commission rates
const hotProductsResponse = await affiliateClient.getHotProducts({
  app_signature: "YOUR_APP_SIGNATURE",
  keywords: "smartphone",
  page_no: 1,
  page_size: 20,
  platform_product_type: "ALL",
  ship_to_country: "US",
  sort: "SALE_PRICE_ASC",
  target_currency: "USD",
  target_language: "EN",
  tracking_id: "YOUR_TRACKING_ID",
});

Dropshipper Client

For dropshipping operations:

import { DropshipperClient } from "ae_sdk";

const dropshipperClient = new DropshipperClient({
  app_key: "YOUR_APP_KEY",
  app_secret: "YOUR_APP_SECRET",
  session: "ACCESS_TOKEN",
});

// Calculate shipping options and costs
const shippingResponse = await dropshipperClient.shippingInfo({
  country_code: "US",
  product_id: 1005004043442825,
  product_num: 2,
  province_code: "CA",
  city_code: "Los Angeles",
  send_goods_country_code: "CN",
  price: "29.99",
});

// Create a dropshipping order
const orderResponse = await dropshipperClient.createOrder({
  logistics_address: {
    address: "123 Main Street",
    city: "Los Angeles",
    country: "US",
    full_name: "John Doe",
    mobile_no: "123-456-7890",
    phone_country: "+1",
    province: "California",
    zip: "90001",
  },
  product_items: [
    {
      logistics_service_name: "AliExpress Standard Shipping",
      order_memo: "Customer order #12345",
      product_count: 2,
      product_id: 1005004043442825,
      sku_attr: "14:350853#Black;5:361386", // SKU specification attributes
    },
  ],
});

🔍 Advanced Usage

    param2: "value2",
    // Additional parameters as required by the API
  },
);
