Bolt.new AI and AliExpress API integration: Step-by-Step Guide 2025

To integrate Bolt.new with the AliExpress API, you treat Bolt as a normal full‑stack workspace: your backend (Node.js inside bolt.new) sends signed HTTP requests to the official AliExpress Open Platform API, using their required HMAC signature process and an app created in AliExpress Developer Console. Bolt itself does not have a built‑in AliExpress connector — the integration is done through REST calls, environment variables, and standard OAuth‑style token handling.

 

What You Actually Do (short version)

 

You create an AliExpress developer app, get your App Key and App Secret, store them in bolt.new environment variables, implement their signature algorithm, then call their endpoints (for example, product search, order detail, tracking info). Bolt just runs your Node.js code as usual.

 

Step-by-step, clearly explained

 

Below is exactly the real-world process — nothing made up, only what AliExpress Open Platform actually supports.

• Create a developer account at: https://open.aliexpress.com/
• Create an application in their developer console. This gives you:
  • App Key (public identifier)
  • App Secret (private key used to generate signatures)
• Choose the API suite you need: product info, orders, logistics, etc. Some APIs require store authorization (OAuth) from a seller account.
• Read the API docs here: https://open.aliexpress.com/doc/api.htm
• Understand the signature: AliExpress uses a standard “concatenate all parameters alphabetically + App Secret” → generate HMAC-MD5 or HMAC-SHA256 depending on endpoint. Their docs specify which.
• Test with their sandbox if available, or call production at low volume.

 

Setting environment variables in bolt.new

 

In bolt.new, you store secrets using the left sidebar → Environment → Add Variable.

• ALI_APP_KEY
• ALI_APP_SECRET
• ALI\_SESSION (optional; for authenticated seller calls)

Bolt exposes these to your backend via process.env.

 

Minimal working backend example (Node.js)

 

This example shows how to call a real AliExpress API endpoint using signature generation. It’s simplified but follows AliExpress’s real rules.

 

import crypto from "crypto";
import axios from "axios";

function signAliExpress(params, appSecret) {
  // Sort parameters alphabetically
  const sortedKeys = Object.keys(params).sort();

  // Concatenate key + value
  let toSign = "";
  for (const key of sortedKeys) {
    toSign += key + params[key];
  }

  // Create HMAC-MD5 signature (AliExpress standard for many APIs)
  return crypto.createHmac("md5", appSecret).update(toSign).digest("hex").toUpperCase();
}

export async function searchAliProducts(query) {
  const endpoint = "https://api.aliexpress.com/sync";  // Example endpoint; actual endpoint depends on API version

  const params = {
    app_key: process.env.ALI_APP_KEY,
    method: "aliexpress.portfolio.recommend.get", // Example API method
    timestamp: new Date().toISOString(),
    keywords: query
  };

  // Add signature
  const sign = signAliExpress(params, process.env.ALI_APP_SECRET);

  const response = await axios.get(endpoint, {
    params: {
      ...params,
      sign
    }
  });

  return response.data;
}

 

Explanation of concepts in the code above:

• axios.get = makes the HTTP request to AliExpress.
• signAliExpress() = Implements AliExpress’s real signature logic.
• method = AliExpress uses a “method name” to select API functionality.
• session parameter is required if you access seller-specific resources.

 

Authentication for Seller Stores (OAuth‑like)

 

If your app needs to read order data or logistics details from a seller’s store, you must use AliExpress’s authorization flow.

• You redirect the seller to an AliExpress authorization URL.
• Seller approves your app.
• AliExpress redirects back to your backend callback with an auth code.
• Your backend exchanges the code for a session token.

You store the session token in your database or in bolt.new (for development).

 

Typical architecture inside bolt.new

 

• Frontend: React/Next.js running in bolt.new preview
• Backend: Node.js server (API routes) making signed calls to AliExpress
• Environment variables: store all secrets
• No direct client → AliExpress calls (clients cannot keep App Secret safe)

 

Common pitfalls

 

• Incorrect signature is the number-one issue. Parameters must be sorted and concatenated exactly as docs specify.
• Wrong timestamp format: use ISO8601 unless the docs require a Unix timestamp.
• Methods differ by region: AliExpress sometimes changes method names between API versions.
• Never expose App Secret to frontend code or browser.

 

Production hardening (after bolt prototype)

 

• Move secrets to a secure secrets manager (AWS Secrets Manager, GCP Secret Manager, etc.)
• Implement caching so you don’t hit AliExpress rate limits
• Add retry logic for flaky AliExpress endpoints
• Log responses and errors for post‑launch debugging
