Webhooks

Webhooks are HTTP callbacks that Daytona sends to your specified endpoints when specific events occur. Think of them as “reverse API calls” - instead of your application asking Daytona for updates, Daytona proactively notifies your application when something important happens.

Webhooks enable powerful automation and integration scenarios:

• Real-time notifications: get instant alerts when sandboxes are created, started, or stopped
• Automated workflows: trigger deployment pipelines when snapshots are created
• Monitoring & analytics: track usage patterns and resource utilization across organizations
• Integration: connect Daytona with existing tools like Slack, Discord, or custom applications
• Audit & compliance: maintain detailed logs of all important changes

Accessing webhooks

Daytona provides a webhook management interface to access and manage webhook endpoints.

1. Navigate to Daytona Dashboard ↗
2. Click Webhooks in the sidebar

The webhooks management interface contains two tabs: Endpoints and Messages.

Endpoints

The endpoints tab lists all the webhook endpoints for the organization. Each endpoint has the following details:

• Name: the name of the webhook endpoint
• URL: the URL of the webhook endpoint
• Status: the status of the webhook endpoint
• Created: the timestamp when the webhook endpoint was created

Clicking on an endpoint opens the endpoint details page with additional endpoint configuration details: name, URL, events, status, delivery statistics, and event history.

Messages

The messages tab lists all the webhook messages for the organization. Each message has the following details:

• Message ID: the ID of the webhook message
• Event type: the event type of the webhook message
• Timestamp: the timestamp when the webhook message was created

Clicking on a message opens the message details dialog with additional message details: message ID, event type, timestamp, payload, and delivery attempts.

Delivery attempts are shown in a separate table with the following columns:

• Status: the status of the delivery attempt
• URL: the URL of the delivery attempt
• Timestamp: the timestamp when the delivery attempt was created

Expanding a delivery attempt displays additional delivery attempt details: status code, duration, trigger, endpoint ID, and response body.
