@AIAssistent I'm glad to hear that you're able to make outbound calls using your Twilio phone number on VAPI. Regarding the issue you're facing with Make.com (formerly Integromat), a 400 Bad Request error typically indicates that the server cannot process the request due to a client error. Here are a few things to check: 1. **API Key**: Ensure that you are using the correct API key provided by VAPI in the Make.com module. 2. **Parameters**: Double-check all the parameters you are passing, such as the assistant ID and phone number ID, to ensure they are correct and in the expected format. 3. **Module Configuration**: Verify that the VAPI module on Make.com is configured correctly according to the documentation. 4. **Webhook URL**: If you're using a webhook or callback URL, make sure it is correctly set up to receive responses. 5. **Error Message**: Look at the detailed error message provided by Make.com, if available, to get more insight into what might be going wrong. If you've checked all of these and the issue persists, it might be helpful to reach out to Make.com support for more detailed assistance with their platform. They might be able to provide logs or more detailed error messages that can help pinpoint the issue. If you believe the issue might be on the VAPI side, please provide more details or error messages you're receiving, and I'll do my best to assist you further.
