## Authentication
To use the Querying API, you need:
- The URL of your Content Hub server. You can get this from your Content Hub
Administrator. Enter this URL in the <b>{{server}}</b> variable by hovering your mouse
over the variable in the <b>Try it</b> pane and then clicking <b>Edit</b>.
- An access token and the client ID. Both are sent with every request. You
can create a token through the [Content Hub
interface](https://doc.sitecore.com/ch/en/users/content-hub/create-an-oauth-client.html)
or by [requesting one using the API
itself](https://doc.sitecore.com/ch/en/developers/cloud-dev/oauth-tokens.html#grant-flows).
