## Authentication
To use this REST API, you must authorize your API requests. To do this, you
need the following information:
- The URL of your XM Cloud Content server (for example, `cs-cmapi.sitecorecloud.io` or a [custom hostname](https://doc.sitecore.com/portal/en/developers/sitecore-cloud-portal/custom-hostnames.html)).
- The environment ID (for example, `main`).

To use the <b>Try it</b> feature, enter this information on the <b>Environments</b> tab, by hovering your mouse over the variable and then clicking <b>Edit</b>.
Tokens are used for API security. You need to generate an OAuth client bearer token and use it to authenticate. A successful authentication request requires the following credential properties: `oauth2_client_id`, the `oauth2_client_secret`, or an `oauth2_token`.
