# Event Types > For the complete machine-readable documentation index, see [llms.txt](https://apidocs.chargebee.com/llms.txt). This is a list of the event types we currently support. We will continue to add more events moving forward. All events follow a uniform pattern - `_`. The resources that will be present in the event content are provided beneath each event type's description. **Note:** If _consolidated invoicing_ is enabled, the attributes _invoice.subscription\_id_ and _credit\_note.subscription\_id_ should **not** be used (as it will not be present if the invoice / credit note has lines from multiple subscriptions). Instead to know the related subscriptions, their line\_items' _subscription\_id_ attribute should be referred. ## List of Events ### addon_created Triggered when an addon is created. ### addon_deleted Triggered when an addon is deleted. ### addon_updated Triggered when an addon is changed. ### authorization_succeeded Triggered when a authorization transaction is created. ### authorization_voided Triggered when a authorization transaction is voided.
