@TimeDrift To send an SMS using a VAPI number, you would typically use the VAPI's SMS API endpoint. You'll need to provide the VAPI number as the sender, the recipient's phone number, and the message you want to send. Here's a general outline of the steps you would follow: 1. Authenticate with the VAPI service using your API credentials. 2. Construct an HTTP POST request to the SMS API endpoint. 3. Include the following parameters in your request: - `from`: The VAPI number you want to use as the sender. - `to`: The recipient's phone number. - `text`: The message you want to send. Please ensure you have the necessary permissions and that your VAPI number is SMS-enabled. If you need specific instructions or have any issues, please let me know, and I can assist you further. If you're ready to send an SMS now and have all the required information, I can guide you through the process.

You can't. It's not possible in any capcity. you would use your own phone provider.

@Chowderr so I need to have a twilio # in Vapi and not use the VAPI wrapper, correct?
c
Its not a Wrapper. its just not your number. So yes you need to use your own.

@TimeDrift To send SMS using Vapi, you need to first build a custom tool which will send a request to your server for sending the SMS. With the help of the custom tool, you can send expected parameters such as receiver number, name, details etc.

Ok so it is possible like @Vapi said @Shubham Bajaj ??
v
@TimeDrift Yes, it is possible to send SMS using VAPI. You would typically integrate with a service like Twilio or another SMS gateway provider that allows you to programmatically send SMS messages. You would use your own number provided by the SMS gateway service, not the VAPI number. Here's how you can do it: 1. Sign up for an SMS gateway service like Twilio and obtain a phone number capable of sending SMS. 2. Use the API provided by the SMS gateway service to send SMS messages. This will involve making an HTTP request with the necessary parameters, such as the 'From' number (your Twilio number), the 'To' number (your client's number), and the body of the message. 3. Integrate this SMS sending functionality into your VAPI application so that when a VAPI agent prompts to send an SMS, your application will trigger the API call to the SMS gateway service. If you need assistance with setting up the integration or have any specific questions about the process, feel free to ask!

@Vapi what does this error mean and how can I fix it? 1 Error Clear All API Error 22:21:47 HTTP error! status: 500 Stack Trace Error: HTTP error! status: 500 at window.fetch (https://115b13e5-ad54-43f3-ae1c-488d98e7d169-00-1xdns1wudst3r.riker.replit.dev/src/components/error/error-tracking-provider.tsx:86:25) at async initializeVAPI (https://115b13e5-ad54-43f3-ae1c-488d98e7d169-00-1xdns1wudst3r.riker.replit.dev/src/components/dashboard/voice-chat-dialog.tsx:62:26) Additional Details { "status": 500, "statusText": "Internal Server Error", "url": "https://115b13e5-ad54-43f3-ae1c-488d98e7d169-00-1xdns1wudst3r.riker.replit.dev/api/vapi/client-token?assistantId=665c9e06-dd35-4971-9191-b0eb335b9f14", "details": "{\"error\":\"Failed to generate VAPI client token: Failed to generate VAPI client token: {\\\"message\\\":[\\\"property assistant should not exist\\\"],\\\"error\\\":\\\"Bad Request\\\",\\\"statusCode\\\":400}\",\"details\":\"Failed to generate client token.

@TimeDrift The error you're encountering is an HTTP 500 Internal Server Error, which indicates that something has gone wrong on the server side. However, the additional details provided suggest that the actual issue is a Bad Request (HTTP 400) error when attempting to generate a VAPI client token. The error message 
"property assistant should not exist"
suggests that there is an unexpected property in the request to the server. It seems that the server is receiving a property named 
assistant
that it does not expect or accept. To fix this issue, you should: 1. Review the API documentation to ensure that you are sending the correct parameters in your request to generate a VAPI client token. 2. Check the request payload to make sure that you are not including any unnecessary or incorrect properties, such as 
assistant
. 3. Verify that your API key is correct and has the necessary permissions to generate a client token. If you've checked these points and the issue persists, it might be a problem with the server or the endpoint itself. In that case, you should contact the support team for the service you're using to get further assistance. If you need help with contacting support or if there's anything else I can assist you with, please let me know!

What should the payload include @Vapi ?
v
@TimeDrift The payload for generating a VAPI client token typically includes the following information: 1. **API Key**: Your unique API key provided by the VAPI service for authentication. 2. **Application ID**: The ID of the VAPI application for which you are generating the token. 3. User ID (optional): A unique identifier for the user on whose behalf the token is being generated, if applicable. Here's an example of what the payload might look like in JSON format:
Copy code
json
{
  "api_key": "your_api_key_here",
  "application_id": "your_application_id_here",
  "user_id": "unique_user_identifier" // Optional
}
Please note that the exact fields required can vary based on the VAPI service you are using. It's important to consult the specific API documentation for the service to ensure you are including the correct parameters in your payload. If you are unsure about the required fields or if you need the exact payload structure for the VAPI service you are using, please ask support for more info on this.
