Small changes on two payment plugins for Woocmmerce

Hello,

We need a code snippet for below two plugins to accept the simple payment option
** simple payment is sending the payemnt request with pre defined customer **
1- https://github.com/paytabscom/paytabs-woocommerce
2- https://wordpress.org/plugins/myfatoorah-woocommerce/

Currently if we send payment withouth customer info we get errors:
1- "Invalid cart description"
2- "request.CustomerName: The field CustomerName is mandatory."

Note: you will only have the plugins, no access to websites
