By supplying your `SPOTIFY_CLIENT_ID` and `SPOTIFY_CLIENT_SECRET`, you get an access token.
## Request token once
To request an access token, build a `ClientCredentialsRequest` and send it via `OAuthClient`. This access token will expire after some time and you need to repeat the process.
```csharp
public static async Task Main()
{
var config = SpotifyClientConfig.CreateDefault();
var request = new ClientCredentialsRequest("CLIENT_ID", "CLIENT_SECRET");
var response = await new OAuthClient(config).RequestToken(request);
var spotify = new SpotifyClient(config.WithToken(response.AccessToken));
}
```
## Request Token On-Demand
You can also use `CredentialsAuthenticator`, which will make sure the spotify instance will always have an up-to-date access token by automatically refreshing the token on-demand.
```csharp
public static async Task Main()
{
var config = SpotifyClientConfig
.CreateDefault()
.WithAuthenticator(new CredentialsAuthenticator("CLIENT_ID", "CLIENT_SECRET"));
var spotify = new SpotifyClient(config);
}
```
:::info
There is no thread safety guaranteed when using `CredentialsAuthenticator`.
