Continue on Error

This workflow demonstrates continue_on_error, which lets a step or action fail without stopping the rest of the workflow — similar to continue-on-error in GitHub Actions. Use case: enrich an alert with optional data from an external API, then always send a Slack notification regardless of whether the enrichment succeeded.

workflow:
  id: continue-on-error-example
  description: "Fetch optional enrichment data and always notify via Slack"
  triggers:
    - type: alert
      cel: source.contains("grafana")

  steps:
    - name: fetch-optional-enrichment
      continue_on_error: true
      provider:
        type: http
        config: "{{ providers.internal-api }}"
        with:
          url: "https://api.example.com/enrich/{{ alert.fingerprint }}"
          method: GET

  actions:
    - name: notify-slack
      provider:
        type: slack
        config: "{{ providers.slack-demo }}"
        with:
          message: >
            Alert: {{ alert.name }}
            Enrichment: {{ steps.fetch-optional-enrichment.results | default('unavailable') }}

How it works:

The fetch-optional-enrichment step calls an external API. If the API is down or returns an error, the failure is logged as a warning and execution continues.
The notify-slack action always runs, using the enrichment results if available or falling back gracefully if not.

The same flag works on actions. In the example below, a best-effort ticket is created in ServiceNow and a Slack message is sent regardless of whether the ticket creation succeeded:

workflow:
  id: best-effort-ticket
  description: "Create a ServiceNow ticket (best-effort) and always notify Slack"
  triggers:
    - type: alert
      cel: severity == "critical"

  actions:
    - name: create-ticket
      continue_on_error: true
      provider:
        type: servicenow
        config: "{{ providers.servicenow }}"
        with:
          table_name: INCIDENT
          payload:
            short_description: "{{ alert.name }}"
            description: "{{ alert.description }}"

    - name: notify-slack
      provider:
        type: slack
        config: "{{ providers.slack-demo }}"
        with:
          message: "Critical alert: {{ alert.name }}. A ServiceNow ticket was attempted."

When continue_on_error: true is set, the step or action failure is logged as a warning but does not mark the overall workflow execution as failed.
