Hello, I tried to create a new block following the API call description here: https://api.qualtrics.com/reference#create-block The call description shows this data, including Block Options: '{ "Type": "Standard", "Description": "My Block Name", "Options": { "BlockLocking": "false", "RandomizeQuestions": "false", "BlockVisibility": "Collapsed" } }' Following this, the new block gets created but without the Options set (plus there is extra item 'SubType': ''). Can someome please cast some light on why the Options are not reflected in the newly created block? Updating a block via PUT method, the Options set works. The attached Python code shows what I tried (needs to have API access token filled in). Oh, actually can't attach a Python code to this post for the .py format is not supported, so providing the code here: https://gist.github.com/zdenekmaxa/a5001b19ffe621aa247e4a13b4ed7b08 Thanks for your answers, Zdenek
