How to implement the authorization using OAuth 1.0

I’m trying to integrate trelloapi with asp .net app, I followed the instruction mentioned in the following link Authorization and I got my access token successfully, but the token was as a fragment in the return_url (expl: http ://localhost:8080/GetToken**#token=…), and in my case I would like to have the token as param (which means ? and not #) in the url (http ://localhost:8080/GetToken**?token=…) server-side app.

After some research I found that the trelloApi uses implicit flow to authorize the user, that’s why the token is as a fragment and to get it as param, I need to use the authorization code flow where the OAuth is needed.

The problem is I didn’t find documentations or examples that helps me to implement the authorization flow which means implementing OAuth. I checked Glitch project and I implemented it in c# but it doesn’t work, it shows message error “OAuth consumer did not supply its key”, and when I added “oauth_consumer_key” as param, I got an other error message “Invalid Signature”.

Please I need help in these 2 points:

1- How can I get the access token as param in the url.

2- I need more details about how to implement OAuth (except those 3 urls provided in Authorization).

Thank you in advance.

Hey pal, hope you are doing well, did you manage to make it work somehow?
I’ve been trying to make some oauth1 authentication work with Trello but had trouble with the return url, as i do not plan to make a server for it.
