As announced previous, the original plan was to close specific sales order endpoints in v1 and v2 by 31/12 2024.
This due date is now changed. We plan to be functional complete with Sales order API v3 by Q2-2024(30th of June 2024), thus new Due date being end of Q4-2024(31st of December 2024). If any change would occur for this, we will announce that as soon as possible.
Planned due date to close specific sales order endpoints in v1 and v2 is 31/3 2025. Find more information here on the planned removal of Sales Order endpoints
