Gazette Data, UK Authentication: API Keys and Security (2026)

Authentication overview

Gazette Data, UK provides access to public notice data through a RESTful API, enabling developers to integrate insolvency, probate, companies house, and local government notices into their applications. Authentication is a prerequisite for interacting with the Gazette Data API, ensuring that only authorized clients can retrieve information. The primary method for authentication involves the use of API keys, which serve as unique identifiers for each client application Gazette Data authentication documentation. These keys are generated within the user's account dashboard and must be included with every API request.

The API key model is a common approach for authenticating to web services, particularly when client-side applications or server-to-server communication requires a straightforward and manageable security mechanism. It allows for granular control over access permissions and can be revoked or regenerated as needed, enhancing security management Google Cloud API key best practices. All communications with the Gazette Data API are secured using HTTPS/TLS, which encrypts data in transit and protects against eavesdropping and tampering.

Supported authentication methods

Gazette Data, UK primarily supports API key authentication. This method is suitable for most use cases, from server-side applications to client-side integrations where the key can be securely managed.

While API keys can be passed as query parameters, Gazette Data, UK recommends using the Authorization header with the format Bearer YOUR_API_KEY for enhanced security in production environments. This practice helps prevent the key from being inadvertently logged by servers or exposed in URLs Gazette Data API key usage.

Getting your credentials

To access the Gazette Data API, you first need to obtain an API key. This process typically involves registering for an account and then generating the key through your user dashboard.

1. Sign Up/Log In: Navigate to the Gazette Data website and either create a new account or log in to an existing one Gazette Data homepage.
2. Access Dashboard: Once logged in, locate your personal dashboard or account settings area.
3. Generate API Key: Look for a section related to 'API Keys', 'Developer Settings', or 'Credentials'. There should be an option to generate a new API key.
4. Store Your Key: Upon generation, your API key will be displayed. It is crucial to copy and store this key securely. Gazette Data, UK will not store it in plain text, and it may not be retrievable later once you navigate away.
5. Configure Access: Depending on your plan, you may need to configure specific permissions or whitelist IP addresses associated with your API key. Refer to the Gazette Data documentation for details on managing API key permissions Gazette Data documentation portal.

For users on the Starter (free) tier, 50 API requests per month are included. Paid plans, starting at £49/month for 5,000 requests, offer increased request volumes Gazette Data pricing page. Your API key will reflect the access level associated with your current subscription.

Authenticated request example

Once you have obtained your API key, you can include it in your API requests. The following examples demonstrate how to make an authenticated request using the recommended method of passing the API key in the Authorization header.

Python Example

import requests

API_KEY = "YOUR_GAZETTE_DATA_API_KEY"
BASE_URL = "https://api.gazettedata.com/v1/"
ENDPOINT = "insolvency-notices"

headers = {
    "Authorization": f"Bearer {API_KEY}",
    "Accept": "application/json"
}

params = {
    "limit": 10,
    "offset": 0
}

try:
    response = requests.get(f"{BASE_URL}{ENDPOINT}", headers=headers, params=params)
    response.raise_for_status()  # Raise an exception for HTTP errors
    data = response.json()
    print(data)
except requests.exceptions.RequestException as e:
    print(f"An error occurred: {e}")

Node.js Example

const fetch = require('node-fetch'); // or import fetch from 'node-fetch';

const API_KEY = "YOUR_GAZETTE_DATA_API_KEY";
const BASE_URL = "https://api.gazettedata.com/v1/";
const ENDPOINT = "insolvency-notices";

async function getInsolvencyNotices() {
    try {
        const response = await fetch(`${BASE_URL}${ENDPOINT}?limit=10&offset=0`, {
            method: 'GET',
            headers: {
                'Authorization': `Bearer ${API_KEY}`,
                'Accept': 'application/json'
            }
        });

        if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
        }

        const data = await response.json();
        console.log(data);
    } catch (error) {
        console.error('An error occurred:', error);
    }
}

getInsolvencyNotices();

These examples demonstrate how to construct an API request with the necessary Authorization header. Replace "YOUR_GAZETTE_DATA_API_KEY" with your actual API key obtained from your dashboard. For more detailed API endpoints and request parameters, consult the Gazette Data API reference documentation.

Security best practices

Securing your API keys and ensuring the integrity of your API interactions with Gazette Data, UK is crucial. Adhering to these best practices can mitigate common security risks:

• Keep API Keys Confidential: Treat your API keys like passwords. Do not embed them directly in client-side code, commit them to version control systems (like Git), or expose them in publicly accessible areas. Store them in environment variables, secret management services, or encrypted configuration files.
• Use HTTPS: Always ensure that your API requests are made over HTTPS (TLS). This encrypts the communication channel between your application and the Gazette Data API, protecting your API key and data from interception during transit. Gazette Data, UK mandates HTTPS for all API interactions.
• Restrict API Key Usage: If Gazette Data, UK offers features to restrict API key usage (e.g., by IP address, HTTP referrer, or specific API endpoints), enable these restrictions. This limits the potential damage if a key is compromised, as it would only be usable from authorized locations or for specific purposes Google Maps API key best practices.
• Rotate API Keys Regularly: Periodically generate new API keys and replace old ones in your applications. This practice reduces the window of opportunity for a compromised key to be exploited.
• Monitor API Key Usage: Regularly review your API usage logs for any unusual activity or spikes in requests that might indicate a compromised key or unauthorized access.
• Error Handling: Implement robust error handling in your applications. Avoid exposing sensitive information, such as API keys, in error messages or logs that might be visible to end-users or unauthorized parties.
• Secure Development Lifecycle: Integrate security considerations throughout your development process, from design to deployment. Conduct security audits and penetration testing where appropriate for applications handling sensitive data.

By following these guidelines, developers can maintain a secure integration with the Gazette Data API, protecting both their applications and the integrity of the data they access.
