Adaptability with a 3rd party plugin?

Hi,

i was wondering, how I can make this plugin work with 3rd party plugin. I’m using the Pay for payment plugin, which add the option to add a fee for Woocommerce Cash on delivery option.

Is it possible to somehow make this plugin work with your plugin? At least to auto-convert the sum?

Regards
