Usage of Events
You can modify the behaviour of some tasks using PSR-11 (Events).
PostProcessApiResponseContentEvent
This event is triggered after the content from avalex server has been retrieved. Here you can adopt changes to the content before it will be written to TYPO3 cache. This is useful to modify contained links like email addresses.
EXT:avalex itself uses this event to modify links in retrieved content. Have a
look into file Event to
use that as an example for your implementation.
