197## Beta to GA migration

198 

199If you still have a beta Realtime integration, migrate it to the GA interface before moving forward with new work. The most important changes are:

200 

201- Remove the `OpenAI-Beta: realtime=v1` header when calling the GA interface.

202- Use [`POST /v1/realtime/client_secrets`](https://developers.openai.com/api/docs/api-reference/realtime-sessions/create-realtime-client-secret) to create ephemeral credentials for browser or mobile clients.

203- Use `/v1/realtime/calls` when establishing WebRTC sessions.

204- Update session and event shapes for the GA interface. In particular, set `session.type`, move output audio configuration under `session.audio.output`, and use the newer response event names like `response.output_text.delta`, `response.output_audio.delta`, and `response.output_audio_transcript.delta`.

205- If you are moving a speech-to-speech app forward, start from the [Voice agents](https://developers.openai.com/api/docs/guides/voice-agents) guide. If you are moving a transcription workflow forward, use [Realtime transcription](https://developers.openai.com/api/docs/guides/realtime-transcription).

206 

207See the [Realtime client events reference](https://developers.openai.com/api/docs/api-reference/realtime_client_events), [Realtime sessions reference](https://developers.openai.com/api/docs/api-reference/realtime-sessions), and [Voice agents](https://developers.openai.com/api/docs/guides/voice-agents) guide for the current GA flow.
