I am new to linnworks.net and I am trying to figure out how to write a macro or order script in linnwork.net. Every tutorial or link i find is about how to do it on desktop version. Please help me out here.
Are you referring to Custom queries for reporting purposes? If so, you can go to Dashboards -> Query data -> select Custom option - you can paste your SQL query here.
If you are asking about scripting functionality - it is currently in a closed BETA stage for .net. If you would like to be able to add a custom macro into .net within the BETA testing - feel free to raise a ticket with such request and our development team will consider this option.
