​
Set your api token

​
Set your material name

This can be any name you like, but names must be unique within your MSI library.

​
Optionally set a code

Use this field if you have a unique material identifier from an external system.

​
Set the category

The category is required. This does not impact calculation but is used for classifying materials in the library. See MSI Get Material Categories for additional information.

​
Set the base materials

Each of your custom material in MSI contains reference(s) to the MSI base materials. These are referenced by a BaseMaterialId. See MSI Get Base Materials for additional information about how to retrieve a master list of base materials and their IDs.

​
Set blend percentages

For blends, simply include the percentage of each base material.

​
Optionally set process ID

Optionally, you can also set a processID to customize things like the raw material source. See MSI Get Processes for Base Material for how to get a list of available processes and their IDs for a given base material.
