I’m using the Box Sign API to send a signature request using the POST /sign-requests endpoint:
https://developer.box.com/reference/post-sign-requests/

I’ve included HTML-formatted text in the email_message field so the email content appears styled (e.g., bold text, line breaks, etc.).

The email is received correctly — the formatting in the email appears to be fine. However, in the signature request view, the email text is displayed with raw HTML tags instead of being rendered as formatted text.

Is there a way to make the HTML render properly in the signature request, or does the API only support plain text for this field?

Thanks in advance for your help!
