Watcher API Is Live: Real-Time NOTAM Shipments to Webhook or Email

The Notamify Watcher API is now live.

Watcher API lets you register listeners for the airports and filters you care about, then receive NOTAM shipments automatically as soon as matching interpretations are available.

After a 3-month testing cycle with our customers and beta testers, the service is optimized and ready for production use.

What Watcher API does

Watcher API is built for teams that need continuous NOTAM monitoring without polling endpoints all the time.

You can configure listeners with filters such as:

• ICAO codes
• categories and subcategories
• Q-codes
• affected elements
• time windows

When a new interpreted NOTAM matches your listener conditions, Notamify sends a shipment to your configured destination.

Delivery target: up to 2-3 minutes

Our target is fast delivery from NOTAM issue time to listener shipment, typically up to 2-3 minutes.

Important detail: shipments are sent on interpretation availability, not raw issuance, and timing depends on listener ICAO coverage and upstream data flow.

Webhook or email delivery

You can receive shipments in two ways:

• Webhook delivery: JSON payloads sent to your webhook_url
• Email delivery: direct email notifications for teams that prefer mailbox-based workflows

Webhook deliveries are signed via X-Notamify-Signature and can be verified with your webhook secret.

SDK support is available

To make deployment easier, we now ship an official Python SDK for Watcher API integration: notamify-sdk. It reduces setup time for listener management, webhook verification, and local sandbox testing.
