We promise true omnichannel, which means that payment processing on the internet, via terminals or at vending machines are not simply individual systems that function in parallel - wallee is a system. Conversely, this means a simple and ingenious API for all possibilities, on all channels. Discover the wallee API.
Whether payment processing on the Internet (e-commerce), in the shop, POS or on the road (terminals) or at vending machines (unattended): At wallee, these are not systems developed in parallel - it is one system. Therefore true omnichannel.
It's one system, no matter which channel you use to realise a payment integration. And this system is an advanced cloud-based solution. This opens up numerous possibilities in all payment integrations.
Cross-channel, intelligent and only one cloud-based system - this means an almost unbelievably powerful but easy-to-use API. With the wallee API, you have access to all operations and can write custom integrations.
In the detailed API reference in our documentation you will find everything you need to know about developing with the wallee REST API: Data models, release notes, types, labels and information on creating web apps.
