How to pre-fill data tag with a date mask

Question

I am creating an envelope using the RES API and have a tag on the document to capture a date (not the date signed, another recipient-supplied date). I can successfully pre-fill the value of this when the mask on the field is Text, but when I switch it to be Date it's blank. "DOBField" is the label of the tag below. Anyone know what I'm doing wrong here?

If you've specified mask of "Date" for the field, then it's no longer a textTab -- it's now a dateTab. So, try changing textTabs to dateTabs in your API request. i.e., the tabs portion of the request will look like this:

"tabs": {
    "dateTabs": [
        {
            "tabLabel": "DOBField",
            "value": "12/24/1976"
        }
    ]
}
