The GST Insights API provides businesses and professionals with a seamless way to access accurate GST (Goods and Services Tax) information in real-time. By integrating this API into your platform, you can validate GST numbers, retrieve return filing statuses, check GST registration details, and more, all while ensuring compliance with the latest tax regulations. Whether you're developing an accounting solution, an e-commerce platform, or a business management tool, the GST Insights API is an essential tool for ensuring that your GST data is always up to date and accurate.

In this blog, we’ll guide you through the process of setting up, integrating, and using the GST Insights API, so you can get the most out of its powerful features.

What is the GST Insights API?

The GST Insights API allows businesses to retrieve detailed and accurate GST information in real-time. With features like GST validation, registration status checks, and return filing data retrieval, this API is crucial for platforms that need to ensure GST compliance and automate verification processes.

Key features of the API include:

  • Real-time GST number validation
  • GST information retrieval by PAN, GST number, or company name
  • Return filing status tracking and historical data access
  • Checking the status of a GST number (active, inactive, suspended)
  • Accessing the registered address linked with a GST number

Now, let’s walk through the steps to set up, integrate, and use the GST Insights API in your application.

Step 1: Register and Get Your API Key

Before you can start using the GST Insights API, you’ll need to register on the API provider’s platform to get your API key. This key will authenticate your requests and allow you to access the API.

  1. Visit the GST Insights API registration page.
  2. Sign up or log in to your account.
  3. Once registered, navigate to the API Keys section and generate a new API key. This key will be required in all your API requests to ensure secure and authorised access.

Step 2: Understand the API Endpoints

The GST Insights API provides several endpoints that you can use to retrieve GST data:

  • /validate-gst: Validate a GST number in real-time.
  • /get-gst-by-pan: Retrieve GST information using a valid PAN number.
  • /get-gst-by-number: Retrieve detailed GST information using a GST number.
  • /get-gst-by-name: Retrieve GST details by providing the company name.

Each endpoint will require different parameters, such as the GST number, PAN number, or company name, depending on what you’re trying to retrieve.

Step 3: Integrating the GST Insights API into Your Application

Once you have your API key and are familiar with the available endpoints, you can start integrating the GST Insights API into your application. The integration process can vary depending on your programming language or framework, but the basic steps are as follows:

Example in JavaScript (Node.js)

Here’s a basic example of how you might use the GST Insights API in a Node.js application to validate a GST number.

  1. Install Required Packages

To make HTTP requests, you’ll need the axios package. Install it using npm:

npm install axios  
  1. Set Up the API Request

Here’s an example function that makes a request to the validate-gst endpoint:

const axios = require('axios');  

const API_KEY = 'YOUR_API_KEY';  // Replace with your actual API key  
const GST_NUMBER = 'YOUR_GST_NUMBER';  // Replace with the GST number you want to validate  

async function validateGSTNumber() {  
  try {  
    const response = await axios.get('https://api.openwebninja.com/gst/validate-gst', {  
      params: {  
        gstNumber: GST_NUMBER,  
      },  
      headers: {  
        'Authorization': `Bearer ${API_KEY}`,  
      },  
    });  

    console.log('GST Number Validation:', response.data);  
  } catch (error) {  
    console.error('Error validating GST number:', error);  
  }  
}

validateGSTNumber();  

This simple function uses axios to make a GET request to the validate-gst endpoint, passing the GST_NUMBER as a query parameter and using the API key for authentication. The response will contain details about whether the GST number is valid or not.

Example in Python

If you're using Python, the requests library is a simple way to interact with APIs. Here's how you can make the same request:

  1. Install Required Packages
pip install requests  
  1. Set Up the API Request
import requests  

API_KEY = 'YOUR_API_KEY'  # Replace with your actual API key  
GST_NUMBER = 'YOUR_GST_NUMBER'  # Replace with the GST number you want to validate  

def validate_gst_number():  
    url = 'https://api.openwebninja.com/gst/validate-gst'  
    headers = {  
        'Authorization': f'Bearer {API_KEY}',  
    }  
    params = {  
        'gstNumber': GST_NUMBER,  
    }

    try:  
        response = requests.get(url, headers=headers, params=params)  
        data = response.json()  
        print('GST Number Validation:', data)  
    except Exception as e:  
        print('Error validating GST number:', e)

validate_gst_number()  

This Python example is similar to the Node.js example, where it sends a GET request to the API and prints out the validation result.

Step 4: Handling API Responses

The GST Insights API returns responses in a structured format, typically in JSON. Here's an example of what a successful response might look like:

{  
  "status": "success",  
  "data": {  
    "gstNumber": "1234567890",  
    "status": "active",  
    "registrationDate": "2020-01-01",  
    "companyName": "ABC Pvt Ltd",  
    "address": "123 Main Street, City, Country"  
  }  
}  

In this response, you’ll receive:

  • status: Whether the request was successful.
  • data: The GST details, such as the GST number, registration status, company name, and address.

Step 5: Using the Data in Your Application

Once you retrieve the GST details, you can use the data to:

  • Display the GST validation status to users.
  • Check the return filing status of a company.
  • Automate compliance checks in your KYC process.

The API allows businesses to integrate GST verification into their platforms quickly, ensuring that all transactions and business relationships are tax-compliant.

Step 6: Error Handling and Best Practices

While working with APIs, it's important to handle potential errors such as invalid API keys, network issues, or incorrect parameters. Always include error handling in your requests to ensure smooth operation in your application.

if (response.status !== 200) {  
  throw new Error('Failed to fetch GST details');  
}

Conclusion

Integrating the GST Insights API into your platform can significantly simplify GST validation, registration checks, and return filing tracking. Whether you're building an accounting system, a business management tool, or an e-commerce platform, the API can help automate GST-related processes and ensure compliance with regulations.

By following this guide, you can quickly set up the GST Insights API, integrate it into your application, and start benefiting from real-time GST data retrieval and validation. This API is a powerful tool for improving efficiency, reducing errors, and ensuring that your business operations remain compliant with GST laws.
