Can you set a field as unique using the arcgis rest api for python?

You can, enabling unique values means adding an index with a unique constraint to the field. To do this in the API you'll want to call the FeatureLayerManager's add_to_definition() function, passing in something like this:

{"indexes":[ {"fields":"MyField", "isUnique":True, "description":"For uniqueness"} ]}

thanks that works - this is the code:

layer = published_item.layers[0]

layer.manager.add_to_definition({

"indexes": [

{

"fields": "some_id",

"isUnique": True,

"description": "For uniqueness"

}

]

})
