Discord made a change to their API that broke widgets.
They already reverted this change, but it will take some time for the revert to deploy.
If your widget is broken for now, please just wait patiently!
See Vendicated/DiscordWidgets#16 for more info.

Discord User Widget

Options

Preview

HTML

<iframe title="Discord user embed" width="340" height=120 frameborder="0" sandbox="allow-scripts" src="" ></iframe>

postMessage() API

The widget supports some commands via window.postMessage() (Docs on mdn)

To use them, you first need to allow the iframe to execute javascript via sandbox="allow-scripts" (this is already the default if you copied the iframe code from above)

The snippets below assume widget is a variable holding the iframe element.
You can for example do this via const widget = document.querySelector('iframe[title="Discord user embed"]')

Change Theme

Theme: light | dark

widget.contentWindow.postMessage({ command: "setTheme", theme: "dark" }, "*")

Change Colours

Change the background and/or foreground colour

widget.contentWindow.postMessage({ command: "setColors", backgroundColor: "#000000", foregroundColor: "#ffffff", }, "*")
