# Updating API version

> Switch your API calls from v1 to v2 in Swagger to enforce role-based access control at the project level.

Update the API version using Swagger to make role-based access calls.

## Steps

1. Add `/swagger/index.html` to your Test Manager instance URL (for example, `https://testmanager.com/swagger/index.html`).
2. Select **Select a definition** at the top of the page and select **V2** from the dropdown list.

## Result

The requests include the version number and use role-based access control in the project's scope.

The following example shows a request with the version number. For the version schedule and the lists of APIs, see [API version](https://docs.uipath.com/test-manager/automation-cloud/latest/user-guide/test-manager-api-version).

```bash
curl -X 'GET' \
  'https://company/testmanager/companyTenant/testmanager_/api/v2/projects' \
  -H 'accept: application/json'
```
