Vapi AI assistant not speaking
Hi everyone!
I’m building an outbound AI caller using Make.com and Vapi.ai. I’m using the create call API via the HTTP module to trigger calls to a Vapi agent.
The issue I’m facing is:
• I’m getting a
201 response
• I do receive the call
• But the AI assistant doesn’t say anything — no firstMessage, no response
I’ve verified that:
• The assistant works perfectly when I test it directly from the Vapi Dashboard (“Try Calling Assistant” button)
• The customer object is included in the payload
• The assistantId is correct
Has anyone faced this? Could this be related to the request format or headers from Make? Any help would be appreciated!
Let me know if you want to attach your payload too for faster support from the community.
