# Set tag value

This is a pre-built Action located under the **WebService Element**. The functionality of this Action in Avo Assure is to set the value of a specific tag (XML or JSON tag value) within the request body of the WebService. The result of this Action updates the request body dynamically for further use during test execution.

## Syntax

**Input Value**: `Tag Value` 

{% hint style="info" %}
**Supported Input Formats**:

* **Text**: Plain string input.
* **Static Value**: A fixed value that you manually provide.
* **Dynamic Variable**: Value retrieved from a previously stored output variable.
  {% endhint %}

| Argument                       | Description                                                                                    |
| ------------------------------ | ---------------------------------------------------------------------------------------------- |
| <p>Tag Value<br>(Required)</p> | Enter the value that needs to be assigned to the specified tag in the Webservice request body. |

**Output Value**: `N/A`

| Argument | Description    |
| -------- | -------------- |
| N/A      | Not Applicable |

{% hint style="info" %}
**Note:** To use the **Set tag value** action, drag and drop the Webservice element from the Element Repository to the Test case. The **Element Name**, **Action** (Keyword), and **Input Value** fields display automatically. The **Set tag value** action becomes available at the Test case level only after the element is added.
{% endhint %}

### Example 1: Setting a Tag Value in a Webservice Request

In this example, we explain how to update or insert a JSON tag value in a Webservice request body.

* **Action**: Set tag value
* **Input Value**: John
  * The input value (**John**) specifies the value that is assigned to the JSON tag.
  * The action updates or inserts the **first\_name** tag in the Webservice request body with the provided value.
* **Output Value**: N/A
  * This action does not require any output value.&#x20;
* **Logical Explanation**: The **Set tag value** action takes the value from the **Input Value** column (**John**) and assigns it to the **first\_name** JSON tag in the Webservice request body. This action modifies the request body directly.

### Example 2: Setting a Tag Value Using a Dynamic Variable

In this example, we explain how to set a JSON tag value using a dynamic variable.

* **Action:** Set tag value
* **Input Value:** {FirstName}
  * The input value (**{FirstName}**) specifies a dynamic variable that stores the value to assign to the JSON tag.
  * The action retrieves the value stored in the **{FirstName}** variable and assigns it to the **first\_name** tag in the Webservice request body.
* **Output Value:** N/A
  * This action does not require any output variable.
* **Logical Explanation:** The **Set tag value** action takes the value from the **Input Value** column (**{FirstName}**). It fetches the value stored inside the dynamic variable and assigns it to the **first\_name** JSON tag.&#x20;

### Example 3: Setting a Tag Value Using a Data Parameterized Value

In this example, we explain how to set a JSON tag value using a data parameterized value from a data source.

* **Action:** Set tag value
* **Input Value:** |FirstName|
  * The input value (**|FirstName|**) specifies a data parameterized field that retrieves its value from an external data source (such as Excel, or Data Table).
  * The action reads the corresponding value for the current iteration and assigns it to the **first\_name** tag in the Webservice request body.
* **Output Value:** N/A
  * This action does not require or store any output variable.
* **Logical Explanation**: The **Set tag value** action takes the value given in the **Input Value** column (**|FirstName|**). It gets the data (John) from the data source. Then, it sets that value to the **first\_name** JSON tag in the request body.

### Example 4: Setting an XML Tag Value Using a Static Value

In this example, we explain how to set an XML tag value using a static (hardcoded) value.

* **Action:** Set tag value
* **Input Value:** John
  * The input value (**John**) specifies a static value entered directly in the Input Value column.
  * The action assigns this fixed value to the **OrderRequest/Customer/first\_name** XML tag in the request body.
* **Output Value:** N/A
  * This action does not require or store any output variable.
* **Logical Explanation:** The **Set tag value** action takes the value from the **Input Value** column (**John**) and assigns it directly to the specified XML tag (**OrderRequest/Customer/first\_name**).
