that’s fine (and the right place anyway)

>Is it possible to set rewards for each type of gateway
at the current time: no, sorry. and there are currently no plans to implement this in the foreseeable future (not unless this is going to be requested many times)

>We also want to be able to make a difference between customers who pay in the shop at pickup and those who pay on-line
you could set discounts/surcharges for each gateway if you wanted, but there is nothing regarding different kind of rewards for different payment methods (see above)

thanks

sorry, for the somewhat late reply.

in any event, the only way you can give a discount for payment gateways that are prepay (i.e credit card payments etc)
is by filtering and forcing discounts (i assume here you know how WordPress filters work, else have a look here https://docs.wp-pizza.com/developers/?section=filters-actions-functions)

something like the following.

add_filter('wppizza_filter_gateway_objects', 'myprefix_myfunctionname');
function myprefix_myfunctionname($obj){
/* 5 EUR/USD/whatever discount */
$obj->MOLLIE->discounts['fixed'] = 5;
/* and or for 5 percent instead */
$obj->MOLLIE->discounts['percent'] = 5;
return $obj;
}

as always , use at your own risk . if you discount for credit card payments you may end up your credit card fee being more than your profit margin on a sale depending on how you set things up if you do the above
