Calling the Flagsmith API to retrieve multiple identities at once fails with "identifier is missing". The question was whether this is a bug or expected behavior, and how to get a list of identities for an environment.

There is no single SDK endpoint that returns multiple identities at once, that is expected behavior, not a bug. To build up identity information you have to use the REST API endpoints individually (the docs linked in the thread), one request per identity identifier. The Flagsmith team confirmed the limitation and updated the Swagger documentation to make it explicit.
