Possible to prevent showing the login form for a single enterprise IDP (preselected with URL parameter)

[user716]

I have a requirement to never display a login page for users of a single external IDP. They open up our application over another DNS address and should then automatically be redirected to the SAML login page of their IDP. I assume this should be possible by specifying the IDP directly as an URL parameter (an URL parameter to the login page of Auth0 preselecting the IDP). I have, however, not found any information about this. Can this be achieved with a rule?

The main goal of this is to never show the end users a login form, when they access our application over their branded URL.

Thanks!

I got a response from the Auth0 support which answers this question:

You can achieve this by passing a connection parameter to the /authorize endpoint. See our documentation on the subject for more information.
