# Add a version to a scripted REST API

Add a new version to a versioned scripted REST API to define new API behavior without impacting older versions.

## Before you begin

There must be a scripted REST Service that has versioning enabled before you can add a new version.

Role required: web\_service\_admin

## Procedure

1.  Navigate to **All** > **System Web Services** > **Scripted REST APIs**.

2.  Select a scripted REST API.

3.  Under **Related Links**, click **Add new version**.

    The **Add new version** pop up appears.

4.  Select **Make this version the default** to configure the REST service to use the new version as the default version.

5.  In the **Copy existing resources from version** choice list, select an existing version to copy all resources from that version to the new version.

6.  Click **OK**.
