I am using vonage phone number in vapi to make calls. To configure it, vapi only asks for api key and api secret along with number from vonage to start making calls via agent. Vapi configures vonage by creating an application on the vonage account and attaching webhook urls for the events triggered by vonage. Ex: for event the url set by vapi on vonage is https://api.vapi.ai/vonage/status Now vonage sends the following payload when call completes after answering { "callId": "id", "headers": {}, "conversationId": "CON-conversationId", "network": "PE-FIXED", "duration": "27", "disconnected_by": "user", "rate": "0.00880000", "price": "0.00396000", "startTime": "2025-04-04T03:08:43.000Z", "from": "51551000-number", "endTime": "2025-04-04T03:09:10.000Z", "to": "5115-number", "status": "completed", "direction": "inbound", "timestamp": "2025-04-04T03:09:09.471Z" } But when I fetch call details from vapi, it only responds me with phoneNumberId which is

conversationId

from the above json. I want vapi to also send over the

price

as well whenever vonage shares this detail. As this whole process of setting the webhooks is automated by vapi, i want a way to also get

price

details from vapi when I fetch call details or via server events triggered.

Hi there! 👋 I understand you're looking for a way to access the Vonage

price

field in Vapi, either through call details or server events. While I couldn't find specific information about whether Vapi currently includes the Vonage

price

field in its responses, I can share what I know about Vapi's handling of call details and potential approaches. ## What Vapi Server Events Are Vapi server events allow your application to receive data and communicate with Vapi during conversations. According to the [Vapi documentation](https://docs.vapi.ai/server-url/events), these events are sent to a Server URL as POST requests and include various types: - Status Updates - Transcript Updates - Function Calls - Assistant Requests - End of Call Report - Hang Notifications The server events follow this structure:

json
{
  "message": {
    "type": "function-call",
    "call": { Call Object },
    ...other message properties
  }
}

## Accessing Call Cost Information Vapi does provide some cost information that you might find useful: 1. **Call Cost Information**: According to the [Vapi changelog](https://docs.vapi.ai/changelog/2024/10/9), you can use

call.costs[type=vapi].subType

to determine if a VAPI cost is

normal

or an

overage

. 2. **Dashboard Cost Breakdown**: You can view a breakdown of your cost per call in your dashboard at [dashboard.vapi.ai/calls](https://dashboard.vapi.ai/calls), which includes STT, LLM, TTS, Vapi platform fee, and Transport (telephony costs). 3. **API Endpoints**: Vapi provides several API endpoints related to calls, including "GET List Calls" and "GET Get Call" which might contain cost information. 4. **Analytics API**: The Vapi analytics API can be used to retrieve usage data, including cost information. ## Potential Approaches Since you're specifically looking for the Vonage

price

field, here are some approaches you might consider:
