How to get external key other than INPUT from RESTFUL request?

SSO callback my api like
api/trpc/user.login?token=abc

Could you describe your problem in more depth?

My company has a project (named center login system) just for user login and logout. I have to combine that to my project.
When my project's user login, it redirects to the login system page. Its backend would callback my tRPC func using get request (like the url api/trpc/user.login?token=abc ) , in purpose to tell me who is login.

But tRPC url request like api/trpc/user.login?input=JSON.stringify(object).
In tRPC, I can't get query params but input

Right, I think tRPC is a bad choice for this

You’d be better off using express for the auth stuff and mount tRPC within express using the adapter for the business API

Thank for your answer. I have solved this question.
I use tRPC context and inject req and res from expressjs.

tRPC doesn't support redirect. https://discord.com/channels/867764511159091230/1084901636146729020

The login system backend callback my url , I have to redirect to my front page in this url.

If I just use expressjs to redirect. This is redundant.I have to develop in both expressjs and tRPC. One for redirect, one for my project code.

It’s completely normal to separate your auth api and business api, but even more expected when you’re essentially implementing OpenId but want to use a non-http standard for the business api. OpenId is http oriented

I’d just pick an OpenId provider like Auth0
