Oauth issues with Trello

I am trying to integrate Trello via Oauth 1.0. and I keep gett the error “app not found.” Any ideas why this is happening? I have created an app, am using the API key and secret found on this page – https://trello.com/app-key

Can you share the API key you are using? This is not the secret (nor is it a token).

You can see a working example of an OAuth 1.0 project here: https://glitch.com/edit/#!/trello-oauth?path=README.md:1:0 I just confirmed that it is working as expected when a proper key and secret are used.
