Passing url parameters to systems like Zitadel

[wtcross]

Zitadel is an open source identity and access management solution. I noticed maennchen/zitadel_api so I'm assuming @maennchen might have implemented what I'm trying to do before.

The Zitadel docs indicate that adding a prompt=create URL parameter to the authorization redirect URL will immediately show the registration page in Zitadel. I have been trying to use Oidcc.Plug.Authorize in my oidcc controller (created by erlef/phx_gen_oidcc) by passing url_extension: [{<<"prompt">>, <<"create">>}] as part of the plug options, but it is not working. The prompt URL parameter is not added to the redirect URL.

Am I missing something obvious?

I forgot to share a link to the Zitadel documentation that I have been referencing. Here it is:

You should be on the right track. There's probably a bug. I'll have a look into it 👍

Does this PR solve your issue? erlef/oidcc#378

[maennchen]

@wtcross Released as v3.2.4.

Thank you so much for the rapid response. That PR does fix the issue! I am very rusty after having not writing any code for ~2 years and am picking a side project back up. Once I get ramped up again I'll hopefully start contributing to these projects. My Erlang knowledge has faded 😅 , but it'll come back.

Your oidcc libraries were very easy to get up and running with on a Phoenix application. Thank you for all the work. I remember there being a gap in the elixir ecosystem from an OpenID Connect perspective when I was last working on this project.

Great to hear that you like working with them. 😄
