Read it from the HTTP response headers of your Text-to-Speech call. The docs’ request‑stitching example shows capturing it from the response headers as request-id. (elevenlabs.io)
Or fetch it afterward from the History API, which returns request_id for each history item. (elevenlabs.io)
Notes:
Both streaming and non‑streaming TTS return headers; the history item may appear with a slight delay, as noted in ElevenLabs’ blog update. (elevenlabs.io)
The Create speech reference also documents previous_request_ids/next_request_ids, confirming request IDs are the intended identifiers to chain generations. (elevenlabs.io)
