Hi there!

Sorry about the late reply.

To specify Paper Tray,

InputSlot = Your value selection

The available value with your Fiery + printer can be acquired by:

GET /live/api/v3/properties/InputSlot

Examples of values will be something like below…

"values": [

This attributes should ignore whatever other media attributes that you set with Fiery API, the attributes should be still there when you open Job Properties but the tray selection will be honored when you print the job.
