Tool Call Webhook Responds, But Vapi Says “No Result Returned”
Hi team,
I’ve set up a tool (CL_fetch_contact_memory) that triggers a Make.com webhook. The webhook works and returns a valid JSON with status 200.
But Vapi keeps saying “No result returned.”
Webhook is responding correctly — so why is the agent not receiving or parsing it?
Example response:
{
"memory_found": true,
"summary": "User previously asked about automation bundle pricing on 21 Sept. Requested follow-up.",
"last_contact_date": "2025-09-21",
"interaction_type": "Web Call",
"lead_status": "Qualified",
"needs_follow_up": "Yes"
}
Please help.
Thanks,
Bishal
