Implementing API Key Authentication via Request Header
Demonstrates how to securely include an API key in the HTTP 'Authorization' header for authentication with external APIs using JavaScript fetch, a common security pattern.
fetch('https://api.example.com/data', {
headers: {
'Authorization': 'ApiKey YOUR_API_KEY',
'Content-Type': 'application/json'
}
})
.then(response => {
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
return response.json();
})
.then(data => console.log(data))
.catch(error => console.error('Error fetching data:', error));
How it works: This snippet shows how to make an authenticated API request by including a static API key in the `Authorization` header. This is a common method for authenticating client applications with a backend service, providing a basic layer of security and access control. The `fetch` API is used to perform the request, handling potential network or server errors. Remember to replace `YOUR_API_KEY` with your actual key.
