Webhook Alerts PRO

How It Works

When a meeting ends and its total cost exceeds the threshold you set, MeetingCost fires a POST request to your webhook URL with a formatted alert message. The message is sent via the MeetingCost proxy endpoint (meetingcostpro.com/api/send-webhook) to avoid browser CORS restrictions — only the alert content is transmitted, not any personal data or transcripts.

The alert payload uses Slack's standard { "text": "..." } format, which is also accepted by Microsoft Teams incoming webhooks.

Alert Message Format

When an alert fires, the message posted to your channel looks like this:
