Conversation Ended Webhook

Intellixent sends a POST request to your configured webhook URL when a chat conversation ends — whether via WhatsApp or your web widget. The payload includes the full transcript, extracted variables, and customer details.

Setup

Enable this webhook using the API:

POST https://portal.intellixent.ai/api/assistants/{assistantId}/enable-conversation-ended-webhook
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json

{
  "webhook_url": "https://your-server.com/webhook/conversation-ended"
}

To disable it:

POST https://portal.intellixent.ai/api/assistants/{assistantId}/disable-conversation-ended-webhook
Authorization: Bearer YOUR_API_KEY

Retry behavior

If your endpoint returns a non-2xx status, Intellixent retries automatically:

Attempt	Delay
1st retry	30 seconds
2nd retry	60 seconds
3rd retry	120 seconds

After 3 failed attempts, the delivery is marked as failed.
