# Set your API key

# 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](/v1.0/reference/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](/v1.0/reference/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.
