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

To integrate Bolt.new with the UPS API, you do not “connect bolt to UPS.” Instead, you write normal backend code inside a bolt.new project that calls the official UPS REST APIs using secure credentials stored in environment variables. In practice, you build a small server (usually Node.js or Python) inside bolt.new, add UPS API keys from the UPS Developer Portal into the bolt environment settings, then call the UPS Shipping, Tracking, or Rate endpoints using standard HTTPS requests. Bolt.new is simply the place where you scaffold, run, and test that code.

 

What Integration Means in Practice

 

UPS exposes a real REST API. Bolt.new is just a browser-based coding sandbox where you write the HTTP calls. You authenticate with UPS using OAuth 2.0 (client_id + client_secret), then you use the returned access\_token to call shipping, rating, or tracking endpoints.

• You get API credentials from the UPS Developer Portal.
• You store them as environment variables in bolt.new.
• You write backend code that fetch() or axios() calls UPS endpoints.
• You run and test everything directly inside bolt’s built‑in server.

 

Step-by-step: How to integrate UPS API inside Bolt.new

 

This is the real, correct sequence for UPS integration in a bolt.new project.

• Create a UPS Developer Account: Go to developer.ups.com and create an app. UPS will issue a client_id and client_secret for OAuth 2.0.
• Enable the APIs you need: In the UPS app settings, enable endpoints like: Track, Rates, Ship, etc.
• Create a bolt.new project: Pick a Node.js or Python template. Node.js is the most straightforward for REST integrations.
• Add environment variables in bolt.new: Go to Environment → New Variable and add:
  UPS_CLIENT_ID
  UPS_CLIENT_SECRET
  UPS_ACCOUNT_NUMBER (if required by the endpoint)
• Implement the UPS OAuth request: UPS requires you to request a token from:
  https://www.ups.com/security/v1/oauth/token using client_id, client_secret, and grant_type=client_credentials.
• Call the actual UPS API (e.g., Tracking): Use the received access\_token in the Authorization header.

 

Working Node.js Example (valid UPS OAuth + Tracking)

 

// server.js
// Minimal UPS integration example in a bolt.new Node.js server

import express from "express"
import fetch from "node-fetch"

const app = express()
app.use(express.json())

// Fetch an OAuth token from UPS
async function getUPSToken() {
  const res = await fetch("https://www.ups.com/security/v1/oauth/token", {
    method: "POST",
    headers: {
      "Content-Type": "application/x-www-form-urlencoded"
    },
    body: new URLSearchParams({
      grant_type: "client_credentials",
      client_id: process.env.UPS_CLIENT_ID,      // stored in bolt.new env
      client_secret: process.env.UPS_CLIENT_SECRET
    })
  })

  if (!res.ok) {
    throw new Error("Failed to get UPS token")
  }

  return res.json()
}

// Example endpoint you can hit from bolt.new UI or frontend
app.get("/track/:trackingNumber", async (req, res) => {
  try {
    const tokenResponse = await getUPSToken()
    const accessToken = tokenResponse.access_token

    const trackRes = await fetch(
      `https://onlinetools.ups.com/api/track/v1/details/${req.params.trackingNumber}`,
      {
        method: "GET",
        headers: {
          Authorization: `Bearer ${accessToken}`,
          "Content-Type": "application/json"
        }
      }
    )

    const data = await trackRes.json()
    res.json(data)

  } catch (err) {
    res.status(500).json({ error: err.message })
  }
})

app.listen(3000, () => {
  console.log("UPS integration server running on port 3000")
})

 

Where this runs inside Bolt

 

Bolt.new will automatically start your Node.js server on port 3000 and provide a preview URL. Any frontend code you scaffold (React, Svelte, vanilla HTML/JS) can call /track/:trackingNumber. Nothing “special” happens in bolt — it’s just real HTTP in a sandbox.

• Environment variables stay inside your bolt project (safe to test).
• All UPS traffic is real, because your server calls UPS directly.
• No fake “bolt tools” — you integrate via real HTTPS APIs.

 

Important Real-world Notes

 

• UPS requires production approval: You start in “test mode,” then request production access when ready.
• Some UPS APIs require shipper number verification (your UPS account must be fully validated).
• CORS: If your frontend is making direct UPS calls, it will fail. Always proxy through your bolt backend.
• Rate limits: UPS applies limits based on your app. Use caching if needed.

 

That’s the complete, real, and valid way to integrate bolt.new with the UPS API: Bolt is just your coding environment; the integration is standard HTTP using UPS OAuth + UPS REST endpoints.
