# Customizable Server Messages

When License server APIs are called, they return error messages that are not customizable. 

For convenience, a small set of these messages can be customized in the License Server's web.config file.

| Setting in web.config                           | Description                                                                                                   | Default Message                                                                  | Place Holders                                                                             |

When customizing the message value, QLM will replace the {x} place holders with the proper value as described in the table above. Extreme caution must be exercised when constructing your message. A badly formatted message might cause an exception in the server.

Example:

{% code overflow="wrap" %}

```xml
<QlmWebService.Properties.Settings>
  <setting name="customMessage_Res_LicenseKeyReleased" serializeAs="String">
    <value>Custom Message: Activation Key {0} has been released from computer {1}.</value>
  </setting>
  
  <setting name="customMessage_Res_AllKeysActivated" serializeAs="String">
    <value>Custom Message: All the available licenses have already been activated.</value>
  </setting>
  
  <setting name="customMessage_Res_LicenseKeyAlreadyActivated4" serializeAs="String">
    <value>Custom Message: The license {0} has already been activated on a system called {1} on {2} [{3}].</value>
  </setting>
```

{% endcode %}
