Per the documentation one of the properties of an envelope is a boolean 'allowMarkup'. I assume this works in conjunction with the settings property located at Preferences >> Account Administration >> Features >> "Allow Markup". I have this option check and I've created a new envelope with the following json:
{
"allowMarkup": true,
"emailBlurb": "Allow Markup Test",
"emailSubject": "Test envelope that should allow to modify docs."
}
After I create the envelope I see the following check box is not checked in the UI :
It seems that i can only set the highlighted property from the UI. Bug? Can anyone reproduce this? We are testing this in sandbox as an FYI.
