I need to add the payment system library to my project on Ocrober CMS ( https://github.com/yandex-money/yandex-checkout-sdk-php ). In this regard, the question is:
Can I do this using only the classes of my plugin, or is there a way to automatically integrate this into the project? If so, how can I do this without rewriting namespace and use at the beginning of php files? There is information about this on Github, but it is not clear how to use it.
