# Basic authentication code samples

Samples of basic authentication code for several programming languages and versions.

## Perl and the SOAP::Lite libraries

To supply basic authentication when using Perl and the SOAP::Lite libraries, you can implement the following function:

```
sub SOAP::Transport::HTTP::Client::get_basic_credentials {
   return 'user_name' => 'password';
}
```

## C\# .NET VS 2005 or older

When using C\# .NET VS 2005 or older, you can take advantage of the Credentials object. For example:

```
System.Net.ICredentials cred = new System.Net.NetworkCredential("user_name", "password");
 
service.ServiceNow proxy = new service.ServiceNow();
service.get getService = newservice.get();
service.getResponse getServiceResponse = new service.getResponse();
 
try
{
  proxy.Credentials = cred;
  getService.sys_id = "bf522c350a0a140701972dbf876f1610";
  getServiceResponse = proxy.get(getService);
catch (Exception ex) { }
```

## C\# .NET VS 2008

When using C\# .NET VS 2008, you can take advantage of the ClientCredentials object. For example:

```
Demo_Incident.ServiceNowSoapClient client = new Test08WebService.Demo_Incident.ServiceNowSoapClient();
client.ClientCredentials.UserName.UserName = "admin";
client.ClientCredentials.UserName.Password = "admin";
```

Then in your `app.config` file look for the following and change "None" to "Basic":

```
<transport clientCredentialType="None" proxyCredentialType="None" realm="" />
```

## VB .NET

When using VB .NET taking advantage of the Credentials object would look like the following:

```
 Sub Main()
        Dim cred As New System.Net.NetworkCredential("user_name", "password")
 
        Dim proxy As New VB_Democm.incident.ServiceNow
        Dim getIncident As New VB_Democm.incident.get
        Dim getResponse As New VB_Democm.incident.getResponse
 
        proxy.Credentials = cred
 
        getIncident.sys_id = "[your sysID here]"
 
        getResponse = proxy.get(getIncident)
 
    End Sub
```

The resulting response when Basic Authentication is turned on and no credentials are supplied looks like this:

```
