Hello! 👋 To retrieve the number of calls made with a particular Assistant ID in a month, you can use either of these two API approaches: ### 1. Using the

/call

Endpoint You can use the

/call

endpoint to filter and view calls by specific assistants:

javascript
const response = await fetch('https://api.vapi.ai/call', {
  headers: {
    'Authorization': `Bearer YOUR_API_KEY`,
    'Content-Type': 'application/json'
  },
  params: {
    assistantId: 'your-assistant-id',
    page: 1,
    limit: 100
    // You'll need to add date filtering parameters
  }
});

### 2. Using the

/analytics

Endpoint (Recommended) This approach gives you more control over time ranges and data aggregation:

bash
curl --location 'https://api.vapi.ai/analytics' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer your_vapi_access_token' \
--data '{
    "queries": [
        {
            "name": "getAnalyticsByAssistantID",
            "table": "call",
            "timeRange": {
                "start": "2024-03-01T00:00:00Z",
                "end": "2024-03-31T23:59:59Z",
                "step": "month"
            },
            "operations": [
                {
                    "operation": "count",
                    "column": "*"
                }
            ],
            "groupBy": [
                "assistantId"
            ]
        }
    ]
}'

Note: For monthly data, make sure to: - Set the

timeRange

to the specific month you want - Change the

step

to "month" - Use

"operation": "count"

instead of "sum" to count the number of calls ⚠️ Important caveat: Some users have reported issues with the

/call

endpoint not properly returning logs filtered by Assistant ID, with endpoints returning empty arrays. The analytics endpoint might be more reliable for this purpose. Hope this helps! Let me know if you need any clarification. Sources:
