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.

This ID must be unique within the scope of your application’s client_id.

The rationale for this is two-fold.

1. When inserting an event, your application doesn’t have to block, waiting for a response from a third-party system in order to receive the ID.
2. Your system doesn’t have store any mapping between your internal IDs and external IDs
