Need help?
We are introducing the next generation of APIs to ensure an improved, more uniform and future-proof integration for your webshop. These new APIs are aimed at improving performance, increasing security and creating more uniformity. We are modernising the technology behind the APIs, making them suitable for our new data models and introducing API Life Cycle Management. This enables us to gather as many changes as possible in a new version so that you can switch optimally in one go.
In 2025, we started rolling out the renewed APIs in phases .As we continue to add new features and improve the experience, more customers will be invited to join and you will be notified in time when it’s necessary to switch.
You can already start exploring the product, functionalities, and see which ones fit your needs.
