# Publish the Workflow to Data Mover

In **Data Shaper**, each workflow must be linked to an **Asynchronous Web Service**, which is listed under the **Asynchronous Web Service** folder. This association is essential for enabling the workflow to be executed by the **Data Shaper 2.0 Processor** service task.

An Asynchronous Web Service acts as metadata that references the **physical path** of the workflow. This path is displayed in the **Filename** field and is used by the system to locate and execute the workflow during processing.

When defining a **mediation contract** in Data Mover, the **Datashaper Payload** drop-down menu will list the Data Shaper workflows of the **Asynchronous Web Service** folder. Selecting a Data Shaper workflow ensures it is triggered correctly.

Refer to the [Defining a mediation contract using the Data Shaper workflow template](/data-shaper-1.21/using-data-shaper-in-data-mover/defining-a-mediation-contract-using-the-data-shaper-workflow-template.md) page for details.&#x20;

#### Creating a New Asynchronous Web Service

To create a new Web Service:

1. Navigate to the **main page**.
2. Right-click on the **Asynchronous Web Service** folder.
3. Select **New** from the context menu.

Complete the form with the following details:

* **Name**: assign a unique name to the Web Service.
* **Filename**: click the **Browse** button and navigate to the physical path of the workflow you want to associate.
* **Workflow Run Configuration**: select **Local**.
* **Status Variables**: this field can be left empty.
* **Content Variable**: leave ASYNC\_CONTENT.

The Web Service will now appear in the **Asynchronous Web Service** folder and be available for selection in the **Datashaper Payload** drop-down when defining a mediation contract.
