Im trying to embed a private card. I got the embed token, but when I load the page, the iframe loads the login page instead of my card
Private embed requires the user be authenticated with the Domo platform in order to view the card. You could try public embed however anyone with the URL link can access that page/card.
I'm assuming having an embed token bypasses the authentication needed, and the card has to be private
The embed token just identifies the card that needs to be embedded, it doesn't provide authorization.
@Kenn, did Grant's reply help you out?
