ClickandBuy API - Service Specifications, Price Lists, Code Examples and Documentation.

ClickandBuy API

The ClickandBuy API allows you to integrate the ClickandBuy online payment system into your applications – ranging from eCommerce applications with a separate architecture to standardized online shop solutions and legacy systems in the area of inventory management. Payments can be made for all kinds of physical goods such as electronics products or books as well as digital goods such as music or document downloads.


  • Only one API for different payment processes
  • Standard protocol: SOAP via HTTP
  • Comprehensive documentation
  • No special knowledge required: can be easily integrated into any software
  • Robust and scalable infrastructure of ClickandBuy: 24/7 availability

Flexible payments in Germany and abroad
ClickandBuy offers 50 national and international payment methods in 120 currencies. You can find a detailed list of all supported currencies in the ClickandBuy documentation.

  • You can map the following business transactions, for example:
  • One-time payments (incl. advance payments)
  • Subscriptions
  • Partial deliveries
  • Payment by installment
  • One-click payment
  • Micropayment

The API is so flexible that new payment processes can be implemented.
If a customer is dissatisfied with the goods purchased or if there are any delivery problems, it is possible to handle rescissions in the form of refunds, credit notes and cancelations.
In this way it is practically possible to map all conceivable eCommerce solutions and online payment transactions for transactions within Germany or internationally.
Before a transaction is executed, several payment processes can be collected in a batch. This makes sense where, for example, different (groups of) individuals are responsible for creating, checking and sending the transaction. This makes it possible to efficiently bundle orders, rescissions or complaints.
If you would like to test your application free of charge before switching to live mode, you can use the sandbox environment.
