I'm having difficult obtaining the call_id. How can I retrieve the call_id when a call is initiated?

@d3athsniper To retrieve the

call_id

when a call is initiated, you would typically use the API response from the call initiation request. When you create a phone call using VAPI, the response should include the

call_id

as part of the call details. If you're initiating a call and need to capture the

call_id

, make sure to check the API response body. The

call_id

should be present there. If you're using a specific programming language or tool, I can provide more detailed instructions on how to extract the

call_id

from the response. Could you please tell me which programming language or tool you're using to initiate the call? This will help me give you a more precise answer.

I'm using python.

@d3athsniper Great! In Python, when you initiate a call using a Voice API, you typically send an HTTP request to the API endpoint and then parse the JSON response to retrieve the

call_id

. Here's a general example of how you might do this using the

requests

library:

python
import requests
import json

# Replace with your actual API endpoint and API credentials
api_endpoint = "https://api.yourvoiceprovider.com/calls"
headers = {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json"
}
payload = {
    # Your payload data here, such as 'to', 'from', and 'answer_url'
}

# Make the API call to initiate the phone call
response = requests.post(api_endpoint, headers=headers, json=payload)

# Check if the request was successful
if response.status_code == 200:
    # Parse the response to JSON
    data = response.json()
    # Retrieve the call_id from the response data
    call_id = data.get('call_id')
    print(f"The call_id is: {call_id}")
else:
    print(f"Failed to initiate call, status code: {response.status_code}")

Make sure to replace

YOUR_API_TOKEN

with your actual API token and

api_endpoint

with the correct URL provided by your Voice API provider. The

payload

should contain the necessary data to set up the call, which will vary depending on the API's requirements. If you encounter any issues or have further questions, feel free to ask!

I am not initiating the phone call via API. I am initiating it via the dashboard @Vapi

@d3athsniper If you are initiating the phone call via the dashboard provided by your Voice API provider, the

call_id

is usually displayed within the dashboard interface after the call has been initiated. Here's what you can typically do to find the `call_id`: 1. Log in to your Voice API provider's dashboard. 2. Initiate the phone call through the dashboard's interface. 3. Once the call is initiated, look for a section in the dashboard that shows active calls or call history. 4. The

call_id

should be listed alongside other call details such as the date, time, caller, recipient, and status. If you're unable to locate the

call_id

in the dashboard, it might be in a detailed view or a separate log section. Some dashboards also provide a search or filter function to help you find specific calls. In case the

call_id

is not visible or you're having trouble navigating the dashboard, I recommend checking the dashboard's help section or contacting the support team of your Voice API provider for assistance. Remember, the exact steps can vary depending on the specific dashboard you're using, so if you need more detailed guidance, please provide the name of the Voice API provider or any additional context that could help.

I am using function calls and my function call needs to know the call_id @Vapi

@d3athsniper If you're using function calls within the context of a Voice API and you need to know the

call_id

, the

call_id

should be automatically provided to your function as part of the event data when a call is initiated or received. When a call event occurs, the Voice API typically sends a webhook to the specified server URL with the call details, including the

call_id

. Your function should be designed to extract the

call_id

from the incoming webhook payload. Here's a simplified example in Python using Flask, which is a common web framework used to create webhooks:

python
from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/webhook', methods=['POST'])
def webhook():
    # Parse the incoming JSON payload
    data = request.json
    # Extract the call_id
    call_id = data.get('call_id')
    
    # Your function logic here, using the call_id as needed
    print(f"Received call_id: {call_id}")
    
    # Respond to the webhook with a success status
    return jsonify(success=True), 200

if __name__ == '__main__':
    app.run(port=5000)

In this example, when a call event occurs, the Voice API sends a POST request to the

/webhook

endpoint with the call details as JSON. The Flask app then extracts the

call_id

from the JSON payload. Make sure your server URL is correctly configured in your Voice API provider's dashboard to point to the endpoint you've set up to handle the webhooks (e.g.,

https://yourserver.com/webhook

). If you're still having trouble receiving or extracting the

call_id

, please ensure that your server URL is correctly set up to receive events from the Voice API, and that your function is correctly parsing the incoming data. If you need further assistance, please provide more details about your setup or the specific issue you're encountering.

@Vapi Is this the correct way to extract the call_id: """def extract_call_id(data: dict) -> str: call_id = data.get('message', {}).get('metadata', {}).get('call_id') if not call_id: print(f"Call ID not found in request data: {json.dumps(data, indent=2)}") raise ValueError("call_id not provided in the request") return call_id """

@d3athsniper The function you've provided for extracting the

call_id

assumes a specific structure of the incoming

data

dictionary, where

call_id

is nested within

message

and then within

metadata

. If this is indeed the structure of the JSON payload you're receiving from the Voice API, then your function is correct. Here's a slightly modified version of your function with an import statement for

json

and proper triple quotes for the docstring:

python
import json

def extract_call_id(data: dict) -> str:
    """
    Extracts the call_id from the provided data dictionary.
    
    :param data: The dictionary containing the call_id.
    :return: The extracted call_id.
    :raises ValueError: If the call_id is not found in the data.
    """
    call_id = data.get('message', {}).get('metadata', {}).get('call_id')
    if not call_id:
        print(f"Call ID not found in request data: {json.dumps(data, indent=2)}")
        raise ValueError("call_id not provided in the request")
    return call_id

Make sure to replace the

data.get('message', {}).get('metadata', {}).get('call_id')

with the correct keys that match the JSON structure you're receiving. If the structure is different, you'll need to adjust the keys accordingly. If you're unsure about the structure of the incoming payload, you can print the entire

data

dictionary to inspect it and determine the correct path to the

call_id

. If you have access to the documentation of the Voice API you're using, it should specify the JSON structure of the webhook payloads, which will help you extract the

call_id

correctly.

@Vapi I am unsure about the structure of the incoming payload. How do i print the entire data dictionary and extract the call_id?

@d3athsniper Certainly! Based on the context provided earlier, here's an example payload that you might receive from a Voice API webhook, which includes the `call_id`:

json
{
  "call": {
    "call_id": "abc12345",
    "to": "+1234567890",
    "from": "+0987654321",
    "direction": "inbound",
    "status": "answered"
  },
  "timestamp": "2023-04-01T12:34:56Z"
}

In this example, the

call_id

is located within the

call

object. To extract the

call_id

from this payload, you would access the

call

dictionary and then get the value associated with the

call_id

key. Here's a Python function that demonstrates how to print the entire data dictionary and extract the `call_id`:

python
import json

def extract_call_id(data: dict) -> str:
    # Print the entire data dictionary to inspect its structure
    print("Received payload:")
    print(json.dumps(data, indent=2))
    
    # Extract the call_id from the data dictionary
    call_id = data.get('call', {}).get('call_id')
    
    # Check if the call_id was successfully extracted
    if not call_id:
        raise ValueError("call_id not provided in the request")
    
    return call_id

# Example usage with the provided payload
payload = {
  "call": {
    "call_id": "abc12345",
    "to": "+1234567890",
    "from": "+0987654321",
    "direction": "inbound",
    "status": "answered"
  },
  "timestamp": "2023-04-01T12:34:56Z"
}

try:
    call_id = extract_call_id(payload)
    print(f"Extracted call_id: {call_id}")
except ValueError as e:
    print(e)

When you run this function with the example payload, it will print the entire payload and extract the

call_id

, which in this case is

"abc12345"

. If the payload structure matches the one provided by your Voice API, this function should work correctly. If the structure is different, you'll need to adjust the

data.get('call', {}).get('call_id')

part to match the actual structure of the incoming payload.

@Vapi My application is expecting the call_id to be at the root level of the JSON object, but in this case, it's nested inside the tool_calls array.

@d3athsniper Yes, based on the JSON structure you've provided, the

call_id

is indeed located within the

call

object and is associated with the key

id

. To extract the

call_id

from this payload, you would access the

call

dictionary and then get the value associated with the

id

key. Here's how you can modify the function to extract the

call_id

from the root level of the JSON object:

python
import json

def extract_call_id(data: dict) -> str:
    # Print the entire data dictionary to inspect its structure
    print("Received payload:")
    print(json.dumps(data, indent=2))
    
    # Extract the call_id from the data dictionary
    call_id = data.get('call', {}).get('id')
    
    # Check if the call_id was successfully extracted
    if not call_id:
        raise ValueError("call_id not provided in the request")
    
    return call_id

# Example usage with the provided payload
payload = {
    "call": {
        "id": "unique_conversation_id"
    },
    "message": {
        # ... rest of the message ...
    }
}

try:
    call_id = extract_call_id(payload)
    print(f"Extracted call_id: {call_id}")
except ValueError as e:
    print(e)

When you run this function with the payload you've provided, it will print the entire payload and extract the

call_id

, which in this case is

"unique_conversation_id"

. If your application is expecting the

call_id

at the root level and the payload structure is consistent with what you've shown, this function should correctly retrieve the

call_id

.

@Vapi Is this the payload sent by VAPI: { "call": { "id": "unique_conversation_id" }, "message": { "timestamp": 1730152041440, "type": "tool-calls", "toolCallList": [ { "id": "tool_call_unique_id", "type": "function", "function": { "name": "Your_Function_Name", "arguments": { // Your function parameters here } } } ], "toolWithToolCallList": [ // Contains function metadata and parameters schema ] } }

@d3athsniper Please ask support for more info on this.

@d3athsniper and @d3athsniper depending on how you initate the call you get the call id in return. Using APIs you get the callId named as

id

in response json. If your using sdk's then you will be get the call id as property named

id

in response to the calls.
