## Client Credentials

Since this grant type (read '[*OAuth Grant Types*](/oauth/grant-types)' section) only allows access to your own account, you only need your OAuth Client ID & Client Secret to generate an Access Token using the Token URL endpoint (https://web.passolution.eu/oauth/token):


```http
POST https://web.passolution.eu/oauth/token
Content-Type: application/json

{
  "client_id": "your-client-id",
  "client_secret": "your-client-secret",
  "grant_type": "client_credentials"
}
```

br
The Token URL endpoint will respond with JSON response containing following fields:


```json
{
  "expires_in": 31536000,
  "access_token": "eyJ..."
}
```
