You have a couple of options.
- If you want the main URL of the app to automatically send you through the SSO process when you’re not logged in, then you can put OIDC.Snip_Login_Automatic on your anonymous user’s home page.
If you want a specific URL, the easiest way to do it would be to:
- create a new page for the anonymous user
- drop OIDC.Snip_Login_Automatic on the page
- in the page properties, use the URL property of the page to set a specific url
There’s also a possibility to expose a REST service at a specific URL, wherein you would get the authorization URL, and redirect the user (just like the flow at the end of the microflow OIDC.webCallback)
