### Answer --- I don't have specific documentation about uploading agents via a web interface file format. The available sources describe creating and updating agents programmatically via the API. For creating agents via the API, the format uses JSON with required fields like

response_engine

and `voice_id`: [(1) ]()

javascript
const agentResponse = await client.agent.create({
  response_engine: { llm_id: 'llm_234sdertfsdsfsdf', type: 'retell-llm' },
  voice_id: '11labs-Adrian',
}) ;

The agent object structure includes fields such as: -

agent_name

-

voice_id

-

response_engine

(with

type

and

llm_id

) -

voice_temperature

,

voice_speed

,

volume

-

language

-

webhook_url

- And many more configuration options If you're looking for a specific file format for bulk upload through the web dashboard, I'd recommend checking the Retell AI dashboard directly or reaching out via: - [Contact Sales]() - [GitHub]() Would you like me to provide a general answer about common agent configuration formats, or more details about the API-based approach?
