You can send a gateway request to Buckaroo in any way you like. But it’s convenient to have a ready-made 'package' for integrating Buckaroo into your checkout: a kit with all the information you need, from activating iDEAL and all other popular payment methods to setting up a ReturnURL*. We developed this PHP SDK (software development kit) in-house. It is easy to use and free to download from GitHub.
* You can find more information about RequestURLs, push messages and ReturnURLs on our support page
This software dev kit contains all the payment logic. It covers not only the connection with various online payment methods, but also all Buckaroo services: subscriptions, credit management and marketplaces. You only use what you need. The SDK also includes plenty of examples. We want to make it as easy as possible for developers to integrate the online store with Buckaroo's checkout.

You control the visual side at the front end. For example, you can choose a one-step checkout or a payment page with multiple steps stacked vertically (accordion checkout). You can also choose a checkout that shows icons for the various payment methods or one with the names written out. In short, you decide how it looks at the front end, and we provide all the technology at the back end.
The PHP SDK is available on GitHub:
