Refund hooks?

[fbas]

I've had to write a payment module to support our organization's payment API. the one piece I have left is refunds.

 

Does anyone have code or documentation or tips on hooking into the refund functionality?

 

thanks

not sure there is a "hookRefund", but you can review the paypal module on how to accomplish performing a refund.

I believe I have found it. hook "cancelProduct" in the back office AdminOrders.php seems to be it.

The problem now is that returning FALSE in cancelProduct does not halt the refund process. Prestashop still marks the product refunded. This is obviously NOT acceptable!!

 

Can anyone give me a pointer or resource to resolve this?

The docs correctly state that this hook is for after the item is deleted from an order. Any ideas about another hook I could use?

 

"Called when an item is deleted from an order, right after the deletion."

have you looked at the paypal module?

I have been reading the Paypal module (that's how I found the cancelProduct hook) and they don't respond to any error in the refund process at all - they just echo out the response values from the PayPal api calls.

 

The paypal module also severely lacks documentation. Not being familiar with the paypal process, it can be hard to understand why the code does what it does.

 

Also, because the cancelProduct hook is called for every line item that has an item being cancelled/refunded, a refund call is made separately for each one. This seems like it could be pretty confusing for the customer to get several refunds rather than one amount.

update: I avoided this approach (using cancelProduct hook) and wrote a new admin tab (based on AdminOrder) in a module with a custom refund hook to let store staff specify a refund price. they have to calculate this themselves.

 

kind of disappointing that prestashop has such poor and neglected support for refunds.

 

as I finish up their shipping scheme, I would like to make a more automatic process that uses the cancelProduct hook to as well as my custom refund hook. my approach will be to use cancelProduct to add line items to a table (indicating they are intended to be refunded, all indexed by the current timestamp), then the refund hook will tally up the refund rows with that index (timestamp), calculate shipping refund and add to that table, issue a refund with my payment processor, then mark those rows as refunded.
