Whether a user wants information about the weather, the stock market, real-time news update and even replies to their chats and comments, nobody feels the need to wait hours for an update or reply.<\/span><\/p>\n

This is where the Newsdata.io Streaming News API comes into frame.<\/span><\/p>\n

Unlike a traditional API that requires you to repeatedly request to get new data and would make you refresh the page many times, a Streaming News API continuously delivers real-time news updates as they become available. Behind the scenes, this is made possible through WebSocket technology, which allows news updates to be sent instantly.<\/span><\/p>\n


\n<\/span>Do not get tense if terms like “Streaming API” or “WebSocket” sound technical. In this guide, we’ll explain everything in simple language and show how the NewsData.io Streaming News API works, and how you can start using it with tools like Postman.<\/span>

What is the Streaming News API?<\/b><\/h2>\n

A Streaming News API is a service that allows the client and server to have real-time, updated communication with a persistent connection.<\/span><\/p>\n

Think about how you normally check for updates. You open a website, refresh the page, and look for new information.<\/span><\/p>\n

Traditional APIs work similarly. Your application asks for data, receives a response, and then asks again when it needs fresh information.<\/span><\/p>\n

Request News<\/span>
\n<\/span> \u2193<\/span>
\n<\/span> Receive Response<\/span>
\n<\/span> \u2193<\/span>
\n<\/span> Request Again<\/span>
\n<\/span> \u2193<\/span>
\n<\/span> Receive Response<\/span>
\n<\/span>\u00a0<\/span><\/p>\n

A Streaming News API works differently. Instead of repeatedly asking for updates, your application connects once and stays connected. Whenever new matching news becomes available, it is automatically delivered to your application.<\/span><\/p>\n

Connect Once<\/span>
\n<\/span> \u2193<\/span><\/p>\n

Stay Connected<\/span>
\n<\/span> \u2193<\/span><\/p>\n

Receive Updates Automatically<\/span>
\n<\/span>
\n<\/span>This approach makes it possible to build applications that react to news as it happens.<\/span>

How NewsData.io Real-Time Streaming Works<\/b><\/h2>\n

Step 1: Register a Query<\/h3>\n

To receive live news updates, you need to register a query<\/b> with NewsData.io.<\/p>\n

Think of a registered query as setting up your personalised news feed. You define what type of news you want to receive by adding filters and parameters. Once registered, the Real-Time Streaming API continuously looks for new articles that match your query and sends them to your connected clients.<\/p>\n

Commonly Used Parameters<\/b><\/p>\n\n\n\n\n\n\n\n\n\n\n\n
Parameter<\/b><\/td>\nDescription<\/b><\/td>\n<\/tr>\n
q<\/b><\/td>\nSearch for specific keywords or topics<\/td>\n<\/tr>\n
category<\/b><\/td>\nReceive news from a particular category, such as Business, Technology, or Sports<\/td>\n<\/tr>\n
country<\/b><\/td>\n“>Get news from specific countries<\/td>\n<\/tr>\n
language<\/b><\/td>\nFilter articles by language<\/td>\n<\/tr>\n
domain<\/b><\/td>\nReceive news from specific publishers or websites<\/td>\n<\/tr>\n
image<\/b><\/td>\nGet articles that contain images<\/td>\n<\/tr>\n
video<\/b><\/td>\nGet articles that contain videos<\/td>\n<\/tr>\n
full_content<\/b><\/td>\nReceive the full article content when available<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

NewsData.io also supports additional parameters such as qinmeta, qintitle, domainurl, prioritydomain, sentiment, tag, region,and others for more advanced filtering.<\/p>\n

You can explore all supported parameters and their usage in the Real-Time Streaming API documentation<\/a><\/p>\n

Important: <\/b>You must provide at least one filter\u00a0<\/b>parameter\u00a0<\/strong>when\u00a0registering a query. A query cannot be registered without a filter.<\/p>\n

Registration Endpoint<\/b><\/p>\n

To register a query, send a POST request to:
\nPOST https:\/\/newsdata.io\/api\/1\/websocket\/register?apikey=YOUR_API_KEY<\/a><\/p>\n

You can include your desired filters as request parameters.<\/p>\n

Example: Register a Query<\/b><\/p>\n

Suppose you want to receive real-time articles aboutArtificial Intelligence<\/b>from theUnited States<\/b>, in English<\/b><\/p>\n

Your request can look like this:<\/p>\n

POST https:\/\/newsdata.io\/api\/1\/websocket\/register?apikey=YOUR_API_KEY&q=artificial%20intelligence&country=us&language=en<\/a><\/p>\n

Here<\/strong>:<\/p>\n
