Why do access_tokens expire and how can you refresh them?
Our API expires the
access_token in order to reduce the risk of your users’ calendar data being compromised. When you obtain authorization to access a user’s calendar, a
refresh_token will be issued alongside the
access_token to allow your application to obtain a new
access_token without user involvement.
Why doesn't Cronofy issue event ids?
We don’t issue IDs to events, instead we require that developers provide an
event_idwhen upserting an event to a user’s calendar. This is then used to identify the event when making subsquent updates/deletes.
What is the difference between event_id and event_uid
event_id is only used for events that your application creates, what we call managed events. This is an ID that your application specifies. We use it as a key for an application’s managed events.
