What it is: Two new filters are now available on the List Session Replays API endpoint. 'amplitude_id' (integer) returns replays tied to a specific Amplitude user ID. 'replay_id' accepts up to 100 IDs in 'device_id/session_id' format and fetches those sessions directly, bypassing pagination. The two filters are mutually exclusive, and when 'replay_id' is used, 'page_size' is ignored and 'next_page_token' is always null.

Where: List Session Replays API. See documentation.

Who: Available for projects with Session Replay enabled (via standard Analytics API credentials)

When: Beta. Available now.
