onEventCanceled( )
Notes:
This method registers a callback function as an event handler.
When
developing websites
or
building apps with Blocks
, use a
Velo backend event
instead of this method.
When building apps not using Blocks, the way you call this method differs depending on the framework you are working in:
When using the
CLI
, run the
generate
command to
add an event extension
, and then call this method within the extension code.
When building a
self-hosted app
,
subscribe your app to the relevant event
, and then call this method on your server.
Triggered when an event is canceled.
