Dear customer,

The TLS/SSL certificate of our Unzer API for domain *, such as or will be replaced on the June 15, 2023.

We strongly recommend that you do not store dedicated certificates on the server side in your system.

On our production system, the change will take place on June 15, 2023 09:00 CEST.

- If the shop systems and web servers do not have the SSL certificate of the respective remote station stored, then no action is required.
- However, if you check the SSL certificate of the payment system in your system, the new certificate must also be stored here.
- You must also check other systems such as merchandise management and fulfillment that are connected to the Unzer system with regard to certificate validation.

Please send an email to for any further questions.

With kind regards,

Your Unzer team
