This transition requires switching to version 2 of the API with the secure OAuth 2.0 authentication protocol. The update ensures that your accounting and sales data keep synchronizing without interruption. It ensures that your account is compatible with current security and invoice issuing standards. ---   #### **How to migrate your Sellsy connection?** In your Shippingbo space, go to your Sellsy sales channel: - In **Sales channels**, search for **Sellsy** and click on the Sellsy account to migrate: ![](https://knowledge.shippingbo.com/hs-fs/hubfs/image-png-Sep-08-2026-02-59-40-6403-PM.png?width=670&height=294&name=image-png-Sep-08-2026-02-59-40-6403-PM.png) - In **General settings**, check the ***use\_oauth2*** option to use the new secure Sellsy protocol: ![](https://knowledge.shippingbo.com/hs-fs/hubfs/image-png-Sep-08-2026-03-01-45-8244-PM.png?width=670&height=320&name=image-png-Sep-08-2026-03-01-45-8244-PM.png) - Then click on **Link / Relink your account**: ![](https://knowledge.shippingbo.com/hs-fs/hubfs/image-png-Sep-09-2026-03-39-49-0169-PM.png?width=670&height=363&name=image-png-Sep-09-2026-03-39-49-0169-PM.png) - A window will appear asking for **your Sellsy login credentials**.
