Custom onpay and split payment questions (IP Commerce)

[Quints]

Hi, I was wondering if it's possible to split payment with the IP Commerce (programming or via the settings tab https://developer.paypal.com/docs/classic/adaptive-payments/integration-guide/APIntro/) and my other question is how would I go about adding custom onpay functions for some of the products? (I wanna keep using the original onpay function for the other products)

Thanks

Commerce does have support for split payments. Basically, if the invoice isn't paid in full, the remainder will remain due. How you handle this with a custom gateway will depend upon the gateway (e.g. you will probably send the split payment amount but you may need to develop a UI to control this at the payment level when a user goes to pay).

You can add an extension for onPay and then check which product was purchased in order to perform actions only for certain products. I did something similar as a hook on \IPS\nexus\Purchase (for onExpire, onDelete and so on) and then I just verify the product that was purchased for the current purchase we are operating on.
