⚠️ Flight Alert API – Notice of Major Update – January 31, 2026
We are transitioning this API to a new system. We are also changing how notification delivery retries work. Read more about it in this guide.
We’re excited to introduce a major new feature: the Flight Alert API. This feature fundamentally changes how flight data is delivered to the applications. Instead of repeatedly polling the flight status or FIDS endpoints to check for updates, you can now subscribe to specific flights or airports and receive automatic notifications whenever changes occur.
Currently, we support webhook notifications. When subscribing, you’ll need to provide a URL that meets certain requirements. That will create a flight alert subscription associated with your account. Our system will then send HTTP POST requests containing JSON-formatted notification data to this URL whenever a flight update occurs as long as the flight subscription lives.
You can subscribe to flight data in two ways: by flight number or by airport ICAO code. This allows you to receive updates for specific flights as well as all movements at particular airports.
We strongly encourage you to review the relevant documentation to understand all details, limitations, and implications. The most important considerations include:
You can try the new Flight Subscription/PUSH API now in our developer playground or in the developer portal of your marketplace (RapidAPI or API.Market).
