How to integrate FlutterFlow with DHL API?

Step-by-Step Guide on Integrating FlutterFlow with DHL API

Step 1: Understand the DHL API

Before delving into the integration, it is critical to have a clear understanding of what the DHL API offers. The DHL API provides various endpoints for tasks such as:

Shipment creation
Shipment tracking
Label generation

Review the DHL API Documentation to familiarize yourself with the available endpoints and required parameters.

Step 2: Create a DHL API Account

Visit the DHL Developer Portal.
Click on the Sign Up button to create an account.
Fill in the necessary details and complete the registration process.
Once registered, log in to the DHL Developer Portal.
Navigate to the API Keys section and generate your API Key and Secret. These will be used to authenticate your requests.

Step 3: Set Up FlutterFlow Project

Open FlutterFlow and create a new project or open an existing one.
Set up your app’s structure and user interface, focusing on where you will integrate the DHL functionalities such as shipment tracking or label generation.

Step 4: Add HTTP Package in FlutterFlow

Go to the Settings in FlutterFlow.
Navigate to the Integrations section.
Look for the HTTP Requests option and enable it.

Step 5: Store API Credentials Securely

Go to the Settings tab.
Click on App State.
Add new API Key and API Secret keys and store your DHL API Key and Secret securely in these fields. This will help you access them dynamically when making API requests.

Step 6: Create HTTP Request

For Shipment Creation:

In FlutterFlow, navigate to Actions.
Create a new HTTP request and name it CreateShipment.
Configure the request as follows:

Method: POST
URL: `https://dhl-api-endpoint/v1/shipments`
Headers:
- `Content-Type: application/json`
- `Authorization: Bearer `

Body (JSON):

        {
          "shipper": {
            "contact": { "name": "Sender Name", "email": "[email protected]" },
            "address": {
              "street": "Sender Address",
              "city": "Sender City",
              "postalCode": "Sender Postal Code",
              "countryCode": "Sender Country Code"
            }
          },
          "recipient": {
            "contact": { "name": "Recipient Name", "email": "[email protected]" },
            "address": {
              "street": "Recipient Address",
              "city": "Recipient City",
              "postalCode": "Recipient Postal Code",
              "countryCode": "Recipient Country Code"
            }
          },
          "packages": [ {
            "weight": "1.0",
            "dimensions": {"length": "10", "width": "10", "height": "10"}
          }]
        }

For Shipment Tracking:

Create another HTTP request and name it TrackShipment.
Configure the request as follows:

Method: GET
URL: `https://dhl-api-endpoint/v1/track/shipments`
Headers:
- `Content-Type: application/json`
- `Authorization: Bearer `
Parameters:
- `trackingNumber`: ``

Step 7: Link API Request to UI

In your FlutterFlow project, navigate to the screen where you want to perform the API action.
Add a button or any widget that will trigger the API request.
Attach the Action of the button to call the CreateShipment or TrackShipment HTTP request.
If required, handle the responses to update the UI dynamically based on the success or failure of the requests.

Step 8: Test the Integration

Run your FlutterFlow app and navigate to the screen where you have integrated the DHL functionality.
Test creating a shipment and tracking a shipment to ensure the implementation works as expected.
Check the console logs for any errors and debug if necessary.

Step 9: Deploy the Application

Once you have thoroughly tested the integration and ensured it is working correctly, you can proceed to deploy your FlutterFlow application.
Follow the standard deployment process for FlutterFlow to publish the app to your target platform (iOS, Android, Web).

With these steps, you should have a comprehensive guide to integrating FlutterFlow with the DHL API, adding robust logistics and shipping capabilities to your application.

FlutterFlow and DHL API integration usecase

Scenario:

An e-commerce company wants to optimize their order tracking for customers. They use FlutterFlow to build a customer-facing mobile app where users can track the status of their shipments. The company decides to integrate DHL's API to fetch real-time tracking information directly into the app, enhancing the user experience.

Solution: Integrating FlutterFlow with DHL API

Mobile App Development:

The e-commerce company uses FlutterFlow to design and develop a mobile application. The app includes a section where users can enter their tracking number to get the status of their shipment.

Setting Up the Integration:

The company installs the DHL API integration within FlutterFlow.
Configuration is done by inputting their DHL API key and other necessary credentials.
Workflows are set up in FlutterFlow to trigger DHL API calls when a user submits a tracking number.

Data Fetching Workflow:

Upon entering a tracking number and hitting 'Track', the workflow is triggered.
A call is made to the DHL API using the provided tracking number.
The DHL API returns the real-time status of the shipment, which is then displayed to the user in the app.

User Experience Improvement:

The app provides details such as current location, estimated delivery time, and any status updates (e.g., "Out for delivery", "Delivered").
Users can opt to receive push notifications for status updates on their shipments.

Monitoring and Analytics:

The company can track and analyze the usage of the tracking feature within the app using FlutterFlow's built-in analytics tools.
Data gathered can help optimize the tracking interface and overall user experience.

Benefits:

Real-time Information: Customers receive up-to-date shipment information, enhancing their trust and satisfaction.
Improved Efficiency: Automating the tracking process reduces customer service workload and allows for more efficient operations.
Enhanced User Engagement: By providing seamless and immediate tracking information, the app encourages repeated use.
Data Insights: The company can monitor how often the tracking feature is used and gather insights into shipment performance.

Conclusion:

By integrating FlutterFlow with the DHL API, the e-commerce company delivers a significantly improved user experience. Customers benefit from real-time tracking information directly within the app, increasing their satisfaction and trust in the company's service.
