Short answer: this isn’t documented as something you can enable on a service account or via API.
What’s documented
Batch Calling and its usage are covered in the product docs, and outbound calling is subject to the Agents Terms and TCPA requirements. There is no published method to programmatically accept “Batch Calling Terms & Conditions.” (elevenlabs.io)
Service accounts are API-only principals managed by workspace admins and gain access through workspace sharing/permissions; the docs don’t describe any UI/legal-acceptance flow for them. (elevenlabs.io)
What to do
Because the public docs don’t specify a way to accept Batch Calling T&Cs for a service account, please have a workspace admin contact ElevenLabs Support (or your account rep) to have Batch Calling enabled for your workspace and confirm any required in-app acknowledgements. (elevenlabs.io)
If you need, I can point you to the exact API references for creating/listing batch calls once your workspace is enabled. (elevenlabs.io)
