I would appreciate it if there would be a 'modified' and 'modified_timestamp tag to the API response of a calevents_list or calevents_details&eventid=<id>.
Modified should then be updated as soon as a status change is made in:
- 'status<id>' in 'raidstatus' (e.g. switching from registered to confirmed)
- start/end date
Since there is no websocket connection to the calendear events nor an easy way to check modifications, it is currently quite cumbersome to detect changed data for an external script.
