Frequently Asked Questions

Common questions about WxWarn:


What are Event Types and Webhooks?

An Event Type referrs to the type of severe weather event (i.e. Tornado Warning, Winter Storm Warning, etc). A webhook is an API feature in which your system registers a location and event type(s) and when the location is affected by one of those events, our system calls your system which allows you to automate responses to severe weather.


Do I need a developer to build an integration?

WxWarn is integrated into Zapier which allows you to build some powerful integrations with other systems you might use without a developer.


Where does the data come from?

All watch and warning data comes from the National Weather Service. It is free for anyone to use but our technology makes it much easier to work with and can monitor specific locations for threats which is not possible with the NWS data feeds.
