When does em_event_save hook fire?

you can use is_admin() – https://codex.www.ads-software.com/Function_Reference/is_admin

em_event_save is fired only on the front end. If you want a hook fired any time an event is saved on either side, use em_event_save_meta

actually, I’m wrong… sorry! It’s used on both front end and backend, whenever an event is saved.

$EM_Event->save() is used exclusively on the front-end, but the actual filter is triggered elsewhere in the admin dashboard.

thanks, do you have an example to how to hook into the em_event_save… something like this?

add_filter(em_event_save', 'updateEvent')

function updateEvent {
//do something

}

yes, look in em-emails.php

there’s one function and it hooks into that filter.
