You get a 404 page not found error

Hosted Login has its own unique terminology and, as a result, its own unique error messages. At heart, however, Hosted Login is a website, which means that you might also encounter standard website errors such as 404 page not found:

Hosted Login’s 404 error means the same thing that a 404 error means anywhere else: you tried to go to page that doesn’t appear to exist.

If you get a 404 page not found error when making an authorization request, that means that problem is somewhere in your Hosted Login URL:

https://v1.api.us.janrain.com/e0a70b4f-1eef-4856-bcdb-f050fee66aae/login/authorize
   ?client_id=a123ef65-83dc-4094-a09a-76e1bec424e7
   &redirect_uri=https://wacky-harmonious-bike.dev.or.janrain.com/redirect_uri
   &scope=openid
   &code_challenge=-xY2YBrATwwfNo2lgk04WjSGqcLF1b2YXwFDG7er5QU
   &code_challenge_method=S256
   &response_type=code
   &state=nzMIwYSkkwKZeRsdW3nQ-KwNIqOWpyvG8ZoHcjlU3bE

For Hosted Login, this often means you made a mistake when entering your customer ID number (in the preceding example, e0a70b4f-1eef-4856-bcdb-f050fee66aae). If you get a 404 error, that’s a good place to start looking for the problem.

Of course, if you’ve CNAME’d your domain then your Hosted Login URL will look a little different:

https://accounts.mydomain.com
   ?client_id=a123ef65-83dc-4094-a09a-76e1bec424e7
   &redirect_uri=https://wacky-harmonious-bike.dev.or.janrain.com/redirect_uri
   &scope=openid
   &code_challenge=-xY2YBrATwwfNo2lgk04WjSGqcLF1b2YXwFDG7er5QU
   &code_challenge_method=S256
   &response_type=code
   &state=nzMIwYSkkwKZeRsdW3nQ-KwNIqOWpyvG8ZoHcjlU3bE

Nevertheless, the problem will still be somewhere in the URL itself. Locate the problem, make the fix, and then try again.
