Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that @elevenlabs/n8n-nodes-elevenlabs is verified or supports 3.0 (used in ElevenLabs - Transcribe Audio).
