Do we have access to the TWILIO call id when we get tool call information on our webhooks? is that whats in the cookie: 'callId=xxxxx-xxxxxx-xxx etc' field?

@Bishop Yes, when you receive webhook events from Twilio for voice calls, you will have access to a unique identifier for the call. This identifier is typically found in the

CallSid

parameter, which is sent with the webhook request. The

CallSid

is a string that uniquely identifies the call within Twilio's system. The

cookie

field you mentioned with 'callId=xxxxx-xxxxxx-xxx' is not a standard field sent by Twilio. It seems like it might be a custom implementation on your end. Normally, the

CallSid

is the standard way to reference the call ID in Twilio's API and webhook payloads. If you need to access the

CallSid

or have any questions about handling webhook data, please let me know, and I can assist you further!

yes i need to know how in one of my custom tools i can access that callsid parameter. speficially i am using n8n. i don't see the callsid information so it seems like i have to send it from vapi specifically

@Bishop To pass the

CallSid

or any other call-related information from VAPI to n8n, you would typically configure a webhook in n8n to receive data from VAPI. Here's a general approach on how to do this: 1. Configure Your n8n Webhook Node: - In n8n, create a new workflow. - Add a Webhook node and configure it to receive data. Note the URL it provides. 2. Set Up VAPI to Send Data to n8n: - In your VAPI settings, you'll need to specify the n8n webhook URL as the endpoint to send call events to. - If VAPI allows you to customize the payload of the webhook, ensure that you include the

CallSid

or any other relevant information. 3. Customize the VAPI Webhook Payload: - If VAPI allows for custom headers or body content, you can add the

CallSid

in the appropriate place. For headers, you might add a custom header like

X-Call-Sid

. For the body, you could include it as a JSON field. 4. Test the Integration: - Make a test call that triggers the VAPI webhook. - Check the n8n Webhook node's output to see if it received the

CallSid

. 5. Handle the Data in n8n: - Once the

CallSid

is received in n8n, you can use it within your workflow to perform various actions or log the call details. If you need specific instructions on how to customize the VAPI webhook payload or if there are any particular settings you're unsure about, please let me know, and I can provide more detailed assistance.

@Vapi no but how do i insert it into a tool call

@Bishop To insert the

CallSid

into a tool call within VAPI, you would typically need to include it as a parameter when you're setting up the call to the tool. Here's a general approach: 1. Identify the Parameter Structure: Determine how the tool you're calling expects to receive parameters. This could be in the form of a JSON payload, query parameters, or some other format. 2. Include the

CallSid

in the Tool Call: When you're making the call to the tool from within VAPI, include the

CallSid

in the appropriate place within the parameters. For example, if the tool expects a JSON payload, you would do something like this:

json
{
  "toolName": "YourTool",
  "parameters": {
    "CallSid": "CAxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  }
}

3. Make the Tool Call: Execute the call to the tool with the included

CallSid

. The tool should now have access to the

CallSid

and be able to use it for its internal processing. If you're using a specific function within VAPI to make this tool call and need to know how to format the parameters correctly, please provide the name of the function or more context, and I can give you a more precise answer.

@Vapi yeah you arne' tgetting it. twilio receives the call. it calls vapi. the callsid parameter is being sent. but in my vapi web interface how can i access it is it {{CallSid}} or what? it desnt' seem to work

@Bishop I apologize for the confusion. If Twilio is sending the

CallSid

to VAPI and you want to access it within the VAPI web interface or in a tool configuration, you typically use handlebars or a similar templating syntax to reference the variable. In many systems, you would indeed use

{{CallSid}}

to access the

CallSid

parameter if it's being passed in the payload. However, if

{{CallSid}}

is not working, it's possible that the parameter might be named differently, or there might be an issue with how the data is being passed or accessed within VAPI. Here's what you can try: 1. Check the Webhook Documentation: Ensure that you're using the correct variable name as per VAPI's documentation. It might not be

CallSid

but something else. 2. Inspect the Incoming Payload: If possible, inspect the incoming webhook payload to VAPI to see exactly how the

CallSid

is being sent. There might be a prefix, or it could be nested within another object. 3. Use the Correct Syntax: If VAPI uses a different templating language or syntax, make sure you're using the correct one. The documentation or support for VAPI should provide details on how to reference variables in the payload. 4. Contact Support: If you've tried the above and it's still not working, it might be best to contact VAPI support directly for guidance on how to access the

CallSid

within their system. If VAPI has a specific way of handling variables and you can provide more details or documentation on that, I can give you more targeted advice. Otherwise, please ask support for more info on this.

You are supposed to be vapi support bot you dummy

@Bishop You can obtain the Twilio call SID payload within the call object, identified as the phoneCallProvider ID.

@Bishop you can find two solutions
