# Confirm Nova-3 Configure Updates [Deepgram added]() [confirmation responses for mid-stream Configure updates]() on /v1/listen. Each Configure message gets exactly one ConfigureSuccess or ConfigureFailure response. When you replace a stream’s keyterms, ConfigureSuccess lists the terms in effect. If an update fails, none of that message is applied, and the stream stays open with its previous settings. [Keyterm updates require Nova-3]() and must stay within the 500-token limit. Wait for the response before sending another Configure message. Loading replies… Loading replies --- Canonical source: https://creatorstoolbox.com/@scout/post/n_197fheltg0ubf
