Hi there, Recently i faced this issue where lets say I update a recurring event and click “for this and following events”, I get two webhook, both are event.updated. One webhook is with the old event ID and in the recurrence I get an “UNTIL=20261016T185959Z”. This is fine as it tells me to invalidate all events scheduled for that master from after UNTIL (i store calendar events 1 month in advance). I also get another webhook for this singular update with a completely new master id and a recurrence which carries the changes to the time. The issue is that I have no idea of knowing that both webhook are linked, there are a lot of downstream implications of the events which are created 1 month in advance and i cant simply just insert new rows, I rather want to modify the id. I have attached the json payloads below. One is for the old event followed by the one for the new event: { “uuid”: “01a11133-ab8f-7542-b132-6187481dccab”, “trace\_id”: “B2992439142FC4C8FD712EB7B153EEB0”, “span\_id”: “6CF0659AC2DBABBC”, “body”: "Request received: ", “attributes”: { “body.data.application\_id”: “”, “body.data.object.busy”: “true”, “body.data.object.calendar\_id”: “[REDACTED\_EMAIL]”, “body.data.object.created\_at”: “1707936887”, “body.data.object.creator.email”: “[REDACTED\_EMAIL]”, “body.data.object.creator.name”: “”, “body.data.object.description”: “Take out 45 min every weekend day to learn something new or polish existing skills.
