How to integrate Lovable with DHL API?

Creating the DHL Integration Service File

Create a new file in your Lovable project’s source folder and name it dhlService.ts.
This file will contain functions that interact with the DHL API using TypeScript.
Copy and paste the following code snippet into dhlService.ts:


// Replace these credentials with your actual DHL API credentials
const DHLAPIKEY = 'YOURDHLAPI_KEY';
const DHLAPISECRET = 'YOURDHLAPI_SECRET';
const DHLBASEURL = 'https://api.dhl.com';

// Example function to track a shipment via DHL API using the tracking number
export async function trackShipment(trackingNumber: string): Promise {
  // Construct the full URL with the tracking number
  const url = ${DHL_BASE_URL}/track/shipments?trackingNumber=${trackingNumber};

  // In place of installing axios via terminal (since Lovable doesn't offer a terminal),
  // we use the native fetch API.
  // If you must use axios, manually include its script tag in your HTML and import it below.
  const headers = {
    'DHL-API-Key': DHLAPIKEY,
    'Content-Type': 'application/json'
  };

  try {
    const response = await fetch(url, { method: 'GET', headers });
    if (!response.ok) {
      throw new Error(`Error fetching tracking info: ${response.statusText}`);
    }
    const data = await response.json();
    return data;
  } catch (error) {
    console.error('Error in trackShipment:', error);
    throw error;
  }
}

Integrating the DHL Service in Your Main Code

Locate the part of your Lovable project where you handle shipments or need DHL integration functionality.
For this example, we assume you have a main TypeScript file (for instance, app.ts) where you want to invoke the DHL API.
Import the trackShipment function in that file and use it as needed. Insert the following code in your app.ts:


import { trackShipment } from './dhlService';

// This function can be triggered when the user needs shipment tracking info.
// For example, it could be attached to a button click event.
async function showShipmentTracking(trackingNumber: string) {
  try {
    const trackingData = await trackShipment(trackingNumber);
    // Process or display the trackingData as required for your app
    console.log('DHL Tracking Data:', trackingData);
  } catch (error) {
    console.error('Failed to retrieve tracking information:', error);
  }
}

// Example usage: Call the function with a dummy tracking number
// Remove or modify this code according to your application flow.
showShipmentTracking('YOURTRACKINGNUMBER');

Adding Automated Dependency Inclusion if Needed

Since Lovable does not allow terminal usage for dependency installation, prefer using the native fetch as shown in the snippet.
If you require a third-party library like axios, include it manually by:
- Downloading the axios library from its official website or CDN.
- Placing the axios file in your project folder.
- Adding a script tag in your main HTML file to load axios, then import it in your TypeScript files.
For instance, to use axios manually include the following in your HTML file inside the <head> section:


<script src="PATHTOYOUR_LIB/axios.min.js"></script>

Then in your code, you can import axios by declaring it as a global variable if required.

Testing Your Integration

Ensure that you replace the placeholder values (YOURDHLAPIKEY, YOURDHLAPISECRET, and YOURTRACKINGNUMBER) with your actual DHL API credentials and test tracking number.
Save the changes to your dhlService.ts and app.ts files.
Run your Lovable project. When the specific function is invoked (for example, via a button click), the DHL API will be called and its response logged to your console.
Check the browser’s console for debugging output or errors.

Finalizing the Integration

Refine error handling and UI notifications in your project as necessary.
Consult the DHL API documentation for additional endpoints and parameters for other shipping functionalities.
Ensure that your API keys are secured appropriately, for example by using environment variables or encrypted storage if Lovable permits such practices.
