Webhook not fetching data in VAPI but works perfectly in RetellAI
Hey everyone ,
I’m facing an issue with my n8n webhook (POST method).
Here’s what’s happening:
I created a POST webhook in n8n.
When I test it using RetellAI, it fetches and triggers data perfectly.
But when I paste the same webhook URL in VAPI, it doesn’t fetch or send any data at all.
I’ve already confirmed the webhook is active and reachable because RetellAI is sending data without issues.
Has anyone faced this issue before? Is there something specific I need to configure in VAPI (like headers, body format, or content type) for it to successfully post data to n8n?
Any help or insight would be appreciated
