# Plugin Configuration

A plugin configuration is structured data in JSON format. Each plugin can have one or more configuration files located in the configuration/<tenant_id>/<plugin_types> directory. The configuration filename must have a .json extension.

The class that implements an API Server plugin **must** provide a constructor method with the following signature:

```plaintext
public <plugin_manager_class_name>(IConfigurationManager configurationManager, String tenantID, String objectType)
```

Where:

- configurationManager is a reference to the configuration manager object.
- tenantID is the tenant identification name.
- objectType specifies the plugin object type. The API Server provides three types of plugin objects: SessionPlugin, TransactionPlugin, and PolicyPlugin.

The configuration manager provides the following two methods:

```plaintext
boolean isObjectCurrent(String tenantID, String objectType, String objectName, long stamp);
```

and

```plaintext
ConfigObject getObject(String tenantID, String objectType, String objectName);
```

Where:

- isObjectCurrent returns true if the required configuration object is recent, in other words, the object’s stamp is more recent than the stamp parameter provided by the caller.
- getObject returns a structure {String data, int stamp} representing data and correspondent stamp for the specified tenantID, objectType, and objectName.
