# Define web service setup for enrichment rule

Use a web service response enrichment rule line to get a field value from another internal or external source, using a web service, and set this value in the target field of the enrichment rule line.

Before you can set up a web service response enrichment rule line:

- Set up the web service to be used.
- Define the web service that applies to the enrichment rule. Also define the desired request parameters setup. The enrichment rule web service and related parameters setup is explained in this topic.

### Request parameters

For a web service, request parameters can be set up. If so, these request parameters are shown on the **Web service setup** page, in the **Request parameters** section.

> [!NOTE]
> **Note**
> 
> If a **Custom request handler** is defined for the web service, no **Request parameters** are available.

You can set up and apply the request parameters in several ways:

- Use the default parameter values, as defined for the applicable web service. In this case, no specific web service parameter setup is required for the enrichment rule.
- Override a default parameter value. To do so, you can use one of these **Parameter types**: **Field**, **Custom**, or **Fixed value**. Each type requires specific setup.

### Steps

1. Click **Data quality management**.
2. On the **Data quality policies** tab, in the list, click the link of the desired data quality policy.
3. Click the **Enrichment rules** tab.
4. Click **Webservice setup**.
5. Click **Edit**.
6. Define the web service that applies to the enrichment rule.

In the **Web service** field, enter or select the desired web service.
7. Click **Save**.
8. Sub-task: Set up a request parameter override of type **Field**.
  1. For request parameters, on the web service, a default value can be defined. You can override this default value with the value of a field.

In the **Request parameters** section, in the list, find and select the desired parameter.

> [!NOTE]
> **Note**
> 
> If no default value is defined for a request parameter, you can also use a field value to define the request parameter value.
  2. Select the **Override setup** check box.
  3. In the **Parameter type** field, select '**Field**'.
  4. Define which field of the enrichment rule source table is used to set the request parameter value.

In the **Field name** field, enter or select a value.
9. Sub-task: Set up a request parameter override of type **Custom**.
  1. For request parameters, on the web service, a default value can be defined. You can override this default value with a value that is defined by a custom method.

In the **Request parameters** section, in the list, find and select the desired parameter.

> [!NOTE]
> **Note**
> 
> If no default value is defined for a request parameter, you can also use a custom method to define the request parameter value.
  2. Select the **Override setup** check box.
  3. In the **Parameter type** field, select '**Custom**'.
  4. Define the custom class that is used to define the request parameter value.

In the **Class** field, enter or select a value.

> [!NOTE]
> **Note**
> 
> You can only select classes that extend the **DQSWebServiceParametersBase** base class. This custom class must have a return method that returns a value.
  5. Define the custom class return method that is used to define the request parameter value.

In the **Method** field, enter or select a value.
10. Sub-task: Set up a request parameter override of type **Fixed value**.
  1. For request parameters, on the web service, a default value can be defined. You can override this default value with a fixed value.

In the **Request parameters** section, in the list, find and select the desired parameter.

> [!NOTE]
> **Note**
> 
> If no default value is defined for a request parameter, you can also use a fixed value to define the request parameter value.
  2. Select the **Override setup** check box.
  3. In the **Parameter type** field, select '**Fixed value**'.
  4. In the **Value** field, type a value.
11. Close the page.
12. Close the page.
