Add Order api

[Nathron]

So I wanted to use add order to price override for shipping, can I use this from a hook then have payment proceed as usual or do I need to cancel the default action somehow and how do I do that. Say in OnBeforeCheckout

 

function inject_beforecheckout($vars){

global $smarty;

pull smarty variables from checkout page total price, my shipping variable add them together to get my real total.

//Create client with details from smarty variables

call addorder from internal api.

//call capture payment here? or is it necessary?

//Generate my own invoice here?

//Prevent default action... Somehow.

}

 

Basically I just want to avoid charging the customer twice for a custom product.

I'll run some test cases now and see what I come up with. Otherwise I'd be willing to pay the creator a modest sum to give me some help with it. Or anybody that can do this in a way that three requirements are met.

 

Shipping shows on the invoice and

The customer pays only once.

Tax works as usual.
