v0 and UPS API integration: Step-by-Step Guide 2025

 

Creating the Package.json Dependency Configuration

 

• Open your existing package.json file in your v0 project code editor.
• Add or update the dependencies section to include the node-fetch package (this package is required for making HTTP requests to the UPS API):

{
  "dependencies": {
    "node-fetch": "^3.2.0"
  }
}
  

• Save the package.json file. This ensures that the node-fetch dependency is available to your project.

 

Creating the UPS Integration File

 

• Create a new file in your project and name it upsIntegration.ts.
• This file will contain all the TypeScript code for interacting with the UPS API.
• Copy and paste the following code snippet into upsIntegration.ts:

import fetch from 'node-fetch';

const UPSAPIURL = 'https://onlinetools.ups.com/rest/Track';
// Replace the placeholders with your actual UPS credentials
const UPSACCESSLICENSENUMBER = 'YOURACCESSLICENSENUMBER';
const UPSUSERID = 'YOURUSERID';
const UPSPASSWORD = 'YOURPASSWORD';
export async function trackUPSShipment(trackingNumber: string) {
  const requestBody = {
    UPSSecurity: {
      UsernameToken: {
        Username: UPSUSERID,
        Password: UPS_PASSWORD
      },
      ServiceAccessToken: {
        AccessLicenseNumber: UPSACCESSLICENSE_NUMBER
      }
    },
    TrackRequest: {
      Request: {
        RequestOption: '1',
        TransactionReference: {
          CustomerContext: 'Your Customer Context'
        }
      },
      InquiryNumber: trackingNumber
    }
  };
  try {
    const response = await fetch(UPSAPIURL, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify(requestBody)
    });
    if (!response.ok) {
      throw new Error(UPS API responded with a status of ${response.status});
    }
    const data = await response.json();
    return data;
  } catch (error) {
    console.error('Error tracking UPS shipment:', error);
    throw error;
  }
}
  



• Make sure to replace YOURACCESSLICENSENUMBER, YOURUSERID, and YOURPASSWORD with your actual UPS API credentials.

 

Integrating the UPS Function into Your Main Code

 

• Open the file where you handle your project’s main logic (commonly main.ts or a similar entry point file).
• Import the tracking function from the upsIntegration.ts file using the following line of code:

import { trackUPSShipment } from './upsIntegration';
  

• Add a function or call within your main program to test the UPS tracking functionality. For example, you can add the following snippet:

async function testUPSIntegration() {
  const trackingNumber = 'YOURTRACKINGNUMBER'; // Replace with an actual tracking number
  try {
    const result = await trackUPSShipment(trackingNumber);
    console.log('UPS Tracking Result:', result);
  } catch (error) {
    console.error('Error:', error);
  }
}

testUPSIntegration();
  



• This will call the UPS API and log the response, allowing you to verify the integration.

 

Configuring Your Project Settings (No Terminal Usage)

 

• Since v0 does not have a terminal, make sure all dependency changes (as shown in the package.json snippet) are manually saved.
• Your project’s build system should automatically detect the new dependency and compile the TypeScript code accordingly.

 

Final Verification

 

• Review all the changes made to ensure the new file upsIntegration.ts is correctly referenced in your main code.
• Ensure your UPS API credentials and tracking number values are correctly set in the respective placeholders.
• Save all files and run your application using your project's built-in run feature.
• Check the console output for the UPS Tracking Result or any error messages to verify whether the integration is successful.
