Kunaki PHP Class
Kunaki is a popular disk publishing service that is fully automated and low-overhead. I went ahead and created an interface layer between Kunaki’s XML web service and PHP. It’s incredibly straight-forward and simple to use and sticts to OOP. It’s fully documented (to the best of my ability, limited by Kunaki’s documentation) and provides example uses.
Here’s a really simple example getting shipping options and pricing for an order:
From here you can have the pick the shipping method you want, fill in the rest of the customer infromation (though you likely already have it), and submit the order.
It should be noted though that you once you submit an order, it still has to be approved in your Kunaki panel. Also, depending on the input data and what you allow, it might not line up with what Kunaki wants and might error out when you submit a request. Error response checking is important and making sure the order gets resubmitted if you’ve already taken payment.
There is no API method to being able to approve orders so I would suggest trying to submit the order first, fix data or prompt the user to fix it if it fails, and then taking payment. Then store the Kunaki order number and the payment gateway information (ex. Paypal order ID) in a table and then using that to approve orders on Kunaki. This should cover your bases but application-specific circumstances always arise. Just be mindful of the limitations of this API.
