Integrate new version
We are renewing and improving our API portfolio to ensure easy and quick implementation. The new API versions will replace the older ones, improving performance and be more scalable. We are also making them safer and more stable with predictable updates. This way, you can enjoy our latest products and services worry-free, today and in the future.
Our new APIs offer version management with predictable updates, allowing for systematic rollouts of new versions. As we continue to add new features and improve the experience, more customers will be invited to join. From January 2026, it will be possible to start using the new APIs and you will be notified in time when it’s necessary to switch.
