# Ping the server

After you set up your authentication method, use `ping` once to verify that the service is up.

```
curl
  -X GET
  -H 'Accept: application/json'
  -H 'Authorization: Basic aHR0cHdhdGNoOmY='
  'https://sandbox-rest.avatax.com/api/v2/utilities/ping'
```

You'll see a response similar to the following upon success:

```
{
  "version": "1.0.0.0",
  "authenticated": true,
  "authenticationType": "UsernamePassword",
  "authenticatedUserName": "TestUser",
  "authenticatedUserId": 98765,
  "authenticatedAccountId": 123456789,
  "authenticatedCompanyId": 123456789,
  "crmid": "1111"
}
```

Tip

You only need to use `ping` once. If you want to verify periodically that the service is running, use a webhook and subscribe to [status.avalara.com](http://status.avalara.com/) instead of pinging multiple times.
