What can be improved in the component code?

Question

Yii

Recently I work on yii2, so I still have very little knowledge of its features. Here it was required to write a component. I ask the gurus for help, what can be improved and how to write components for yii2 in general? Any criticism, even the smallest, is welcome.

Thank you in advance for your time.

As far as I can see, you don't have to inherit yii\base\Component, yii\base\Object is enough. Component adds behavior (Behavior) and events (Event) to the object. You seem to use only the "magic" configuration that is in Object.
Also, I would place all the parameters of the component in config/main.php or in main-local.php, and would access it through Yii::$app->robokassa->... but this is subjective.
