This page lists the different action tasks supported in Data Orchestrator workflow definitions.

      ```yaml
      document:
        dsl: 1.0.3
        namespace: <namespace_name>
        name: <workflow_name>
        version: 1.0.0
      do:
      - task:
          call: "serverless_job"
          metadata:
            description: "The first job"
          with:
            id: "<Serverless_job_ID>"
            region: "fr-par"
      ```
    Replace the ID placeholder with the ID of your Serverless Job. You can copy it from the [Serverless Jobs page](https://console.scaleway.com/serverless-jobs/) of the console.
