Who Supports the Pipe Dream Here?

I did it in above link but I cannot still use end user feature

for now I can do it with following method

but as you know, this is not good for many users

I cannot create the node for hundred of users

what I want is that I use this one in trello

Sergio’s interpretation is correct — Trello only supports OAuth 1.0 (which is crazy), and that’s not support with our custom OAuth client model, which is required for running workflows for your end users.

So unfortunately this won’t work for Trello right now
