I can't seem to connect an API between hubspot to VAPI. I'd like to update a field in hubspot call "send to vapi" to yes, when I do that it triggers an API call to VAPI to initiate an outbound call from one of the agents I built.

Set up a HubSpot workflow to trigger when the “send to vapi” field is set to “yes,” and use a webhook action to send a POST request to Vapi’s API https://api.vapi.ai/v1/call with the assistant ID, phone number ID, and the contact’s phone number, ensuring the correct JSON format and authentication headers are used..
