Hii @srpalmer, Welcome to Icinga Community.

Yes, there were syntax errors but they have all been fixed and is already merged. You just have to look at [snapshot doc](https://icinga.com/docs/icinga-2/snapshot/doc/12-icinga2-api/#event-stream-response) and not the [latest](https://icinga.com/docs/icinga-2/latest/doc/12-icinga2-api/#event-stream-response).

And the same question was asked and answered [here](https://community.icinga.com/t/eventstream-filter-api-question/6575/2). You can take the API queries from there.

Hope this’ll Help you!
