Events API provide event push as well as historical queries via SSE (server sent events).
Historical events are streamed immediately if queried, and updates are pushed as events occur.
Query Params Rules:
since_idcan’t be used at the same time
since_idnot specified this will not return any historic data
until_idreached stream will end (status 200)
Note for people using the clients generated from this OAS spec. Currently OAS-3 doesn't have full support for representing SSE style responses from an API, so if you are using a generated client and don't specify a
until there is a good chance the generated clients will hang waiting for the response to end.
If you require the streaming capabilities we recommend not using the generated clients for this specific usecase until the OAS-3 standards come to a consensus on how to represent this correcting in OAS-3.
