If-match required?

[adrianm]

In the SalesOrderApi if-Match is required
> "If-Match header represents a version of Sales Order to be modified and must be included in request"

Visma.net ERP Api has exactly the same wording but if-match is not required when I test it.

> If-Match header represents a version of Purchase order to be modified and must be included in request.

Is there a plan to also make if-match required in Visma.net ERP API?

Hello, it is required in the neXtgen Sales Order Service; however, it has only recently been implemented in the VismaNet ERP API  and is currently optional. At this time, there are no plans to make it mandatory for requests.
