Integrate GIVEWP plugin with our provider’s payment gateway - COUNTRY PERÚ

We have a wordpress website that uses the GiveWP plugin to accept donations, as it has limited payment gateways that don't work with us, we have payment gateway providers in our country that we want it to integrate with "fully", as if Stripe and GiveWP were being used.

The payment gateway can be:
MERCADOPAGO: https://www.mercadopago.com.pe/developers/es/reference
EITHER
NIUBIZ: https://desarrolladores.niubiz.com.pe/#section-api

Documentation about the plugin can be found here:

Thank you
