### Answer To export daily call analytics for a specific voice agent, you can use Retell's List Calls API filtered by

agent_id

. [(1) ]() From the returned call data, you can calculate metrics like: - Total calls - Average call duration - Successful and unsuccessful calls You can also export call history data directly from the dashboard using selected filters and column settings, which mirrors the call history table. [(2) ]() For programmatic access, the analytics dashboard allows you to: - Monitor key metrics like call success rate, transfer rate, call counts, and latency - Create custom charts tailored to your needs - Dive deep into programmatic calls for troubleshooting Check out these potentially useful sources: - [List Calls API]() - [Call Analytics Glossary]() - [Platform Changelogs]() Would you like me to provide a general answer on how to structure the API call to retrieve this data?

@AI Evy i need api, which will help me extract call details and variables that i extracted from the call agent

### Answer To extract call details and variables collected during calls, use the List Calls API (

POST /v2/list-calls

) . [(1) ]() Example:

javascript
import Retell from 'retell-sdk';
const client = new Retell({
  apiKey: 'YOUR_RETELL_API_KEY',
}) ;
const callResponses = await client.call.list() ;
console.log(callResponses) ;

You can filter by

agent_id

to get calls for a specific agent:

json
{  
  "agent_id": ["agent_oBeDLoLOeuAbiuaMFXRtDOLriT12345"]
}

Key fields returned include: -

call_id

,

agent_id

,

call_status

,

duration_ms

-

transcript

and

transcript_object

(with timestamps) -

collected_dynamic_variables

– contains variables extracted during the call (e.g.,

{"last_node_name": "Test node"}

) -

retell_llm_dynamic_variables

– dynamic variables injected into the call -

call_analysis

– includes

call_summary

,

user_sentiment

,

call_successful

, and

custom_analysis_data

-

recording_url

and

public_log_url

The

collected_dynamic_variables

field specifically holds the variables your agent extracted during the conversation.
