@MFG Hello! I'm glad to assist you with your issue regarding dynamic variables. It sounds like you've done a thorough job of ensuring that the

firstname

variable is being passed to the VAPI webhook. If the dynamic variable isn't being used in the voice call as expected, there are a few things we can check: 1. **Variable Format**: Ensure that the variable is being passed in the correct format expected by VAPI. The dynamic variable should be enclosed in double curly braces like

{{firstname}}

when used in the VAPI script. 2. **Script Configuration**: Verify that the script you have set up in VAPI is correctly configured to use the dynamic variable. The placeholder for the variable should be present in the script where you want the name to be spoken. 3. **Webhook Configuration**: Double-check the webhook configuration to make sure that the

firstname

parameter is being sent in the payload to VAPI. 4. **Debugging**: Use logging or debugging tools within make.com (formerly Integromat) to inspect the actual data being sent to VAPI. This can help you confirm that the

firstname

variable is not only being passed but also in the correct format. 5. **Documentation**: Review the documentation on dynamic variables on the VAPI website to ensure that there isn't a step or configuration that you might have missed. If you've already tried hardcoding the name and it's still not being spoken, it could be an issue with how the VAPI script is handling the variables. If you can provide more details about how you're setting the dynamic variable in the script or share a snippet of the script where the variable is used, I might be able to offer more specific advice. If you've checked all of the above and the issue persists, it might be best to reach out to VAPI support for further assistance. They can provide more detailed guidance and help troubleshoot the issue with you.
