To learn more about how to create a new Test Case Folder and Test Case, [click here](https://docs.avoautomation.com/working-with-the-avo-assure-platform/create-and-execute-tests-with-design-studio/working-with-test-case-section/creating-test-case).
## Creating New API Test Step Group
To add a Test Step Group in a Test case, perform the following actions:
1. On the **Home** page, select the required project and select **Design Studio**.
2. Go to the **Test Case** tab and select the created Test case.
3. On the **Test Case** tab, select **Create Test Step Group** and select **Add new test step group**. The **Test Step Group** dialog opens.
4. Enter the name in the **Test Step Group Name** text box and select **Webservice** as an **Application Type**.
5. Select **Create** to add a new Test Step Group.
{% hint style="info" %}
**Note**: You can also add a **Test Step Group** from the [**Reusable Library**](https://docs.avoautomation.com/working-with-the-avo-assure-platform/create-and-execute-tests-with-design-studio/working-with-test-case-section/creating-test-step-group/add-test-step-group-from-reusable-library).
{% endhint %}
6. This creates a new **Webservice Test Step Group** inside the Test case.
7. Select the required options to add the Test Steps. \
Here are the two ways to add steps:
* **Add from repository**
* **Add Manually**
Add from repository
To add Webservice elements from the Element Repository to the Test Step Group, perform the following actions:
1. On the **Test Case** tab, select the created Test Step Group and select **Add from Repository**. The **Element Repository** page opens.
2. From the **Element Repository** page, drag-and-drop the **Webservice** elements repository into the **Test Step Group**.
{% hint style="info" %}
**Note**:
* Once you drag and drop elements from the **Element Repository** in a **Webservice Test Step Group**, all **JSON** and **XML** keys, including parent and nested keys, are available in the **Element Name** dropdown, and the **Element Name**, **Action** (Keyword), and **Input Value** fields automatically populate in the Test Steps.
* After dragging and dropping elements from the Element Repository into a Webservice Test Step Group, all JSON keys, including parent and nested keys along with their array values become available in the **Element Name** dropdown.
{% endhint %}
3. Select **Save** to save the Test Steps.
Add Manually
To add Webservice elements manually to the Test Step Group, perform the following actions:
1. On the **Test Case** tab, select the created Test Step Group.
2. Select **Add Manually** to add a new Test Step.
3. Select **Add Step** (**+**) icon and select **Add step manually** to add more steps to the **Test Step Group**.
{% hint style="info" %}
**Note**: You can also add multiple Test Step by selecting the **Add Step** (**+**) icon for an individual step.
{% endhint %}
4. A new **Test Step** is created. Select the **Webservice List** as an **Element Type** and **Action** from the dropdown.
4. Select **Save** to save the Test Steps.
{% hint style="info" %}
**Note**: To run the created Test Steps, you can either select **Debug** or create an [**Execution List**](https://docs.avoautomation.com/working-with-the-avo-assure-platform/create-and-execute-tests-with-design-studio/working-with-execution-section/execute-execution-list).
{% endhint %}
#### Key Points to Know
* You can directly create a Test Case and perform API testing without executing any API request from the **Element Repository** page.
* To automate Webservice in Avo Assure, there is no need to capture application elements as APIs work in the backend.
* To automate Webservice applications successfully, it is important to understand the correct actions, applicable to your application. For a detailed list of supported Webservice list actions, to view the article, [click here](https://docs.avoautomation.com/actions/web-service-operations).
