Linnworks macros are small snippets of code or scripts written in C# that automate tasks within the Linnworks system Linnworks provides an API (Application Programming Interface) that allows developers to interact with and manipulate data within the Linnworks platform. Macros leverage this API to perform various actions such as updating orders, managing inventory, generating reports, and more. They are of two types: 1. Rules Engine macros allowing users to run a snippet of the C# code on every open and paid order that gets downloaded into the system. 2. Scheduled Macros allow users to run the custom C# code on the user defined schedules.
