Individual integration?
Easy made.

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.
