How do I fix parameters being ignored in the JavaScript SDK?

Ensure you are using camelCase (e.g., modelId, voiceId) instead of snake_case. While the API and Python SDK use snake_case, the JS SDK requires camelCase for parameters to be recognized.

Can my ElevenLabs agent use custom documentation?

Yes, you can configure a Knowledge Base by uploading documents and computing a RAG index, allowing the agent to retrieve relevant information during the conversation.

Which ElevenLabs SDK should I use for a web browser project?

Use @elevenlabs/react or @elevenlabs/client. Avoid @elevenlabs/elevenlabs-js in the browser as it depends on Node.js child_process and will cause build errors.

What is the new tool configuration format for 2025?

The legacy prompt.tools array is deprecated. You must now use prompt.tool_ids for custom tools and built_in_tools for system functions like 'end_call'.
