Outbound Webhooks

Outbound webhooks send a notification to a URL of your choice whenever an endpoint finishes executing. Use them to post to Slack, trigger downstream workflows, or log results to external systems.

Setting up a webhook

From wrapd.yaml

Add notify_url and optionally notify_on to an endpoint:

endpoints:
  - name: deploy
    method: POST
    command: ./deploy.sh
    notify_url: https://hooks.slack.com/services/T.../B.../xxx
    notify_on: always

From the dashboard

Open Dashboard → Endpoints, click an endpoint, and set the Notify URL and Notify On fields.

Notify conditions

Value	Fires when
always	Every execution (default)
success	Command exits successfully (exit code 0)
failure	Command fails (non-zero exit code)

What’s included

The webhook POST includes the endpoint name, exit code, status, duration, and command output. If the endpoint is marked as sensitive, the output is omitted.

Pipeline webhooks

Pipelines also support notify_url. The webhook fires once after the entire pipeline run completes — not per step.

Use cases

• Slack notifications — post deployment results to a channel
• Logging — forward execution results to Datadog, Loki, or a custom log sink
• Chaining — trigger another service after an endpoint completes
• Alerting — use notify_on: failure to alert only when something breaks
