Hi Arien22,

Please move your "tabs" list to your Signers object. Like this:

"signers": [
            {
                "email": "adrianc@gmail.com",
                "name": "Arlen Redacted",
                "recipientId": "1",
                "routingOrder": "1",
                "tabs": {
                    "signHereTabs": [
                        {
                            "documentId": "1",
                            "height": "0",
                            "isSealSignTab": "false",
                            "name": "SignHere",
                            "optional": "false",
                            "recipientId": "1",
                            "scaleValue": "1",

The website docs seem to indicate that I can include it in either location. In my case, I can move it and it works fine then, but it seems like the docs should be updated at the very least or else this is a bug that needs to be fixed.
