# Generate a test event notification API improvements

In the Generate a test event notification API request, we have introduced a set of additional fields. In your request, you can now set `eventType`, `version`, and any related details about the information you want in the test event notification. You can get the BILL events catalog with `GET /v3/events/catalog`.

See [POST /v3/subscriptions/\{subscriptionId}/test](https://developer.bill.com/reference/sendtestevent)  in the API reference for more information.
