> The Client Credentials flow is used in server-to-server authentication.

> Only endpoints that do not access user information can be accessed.

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 ClientCredentialsAuthenticator("CLIENT_ID", "CLIENT_SECRET"));
|
|
|
|
var spotify = new SpotifyClient(config);
|
|
}
|
|
```
|
|
|
|
:::info
|
|
Thread safety is not guaranteed when using `CredentialsAuthenticator`.
