Oauth error invalid_request: The redirect_uri is not whitelisted

[rony36]

Not sure what is the problem with my app.

In App setting defined redirection URL and same URL is presented in OAuth URL.

Why I've getting this error, it's frustrating

I'm guessing Shopify doesn't let you append your own URL parameters, i.e., your response_type = code 

Edit: Sorry, nevermind that's appended by Shopify. Can you confirm that the client_id matches the same app as the screenshot you shared in the partner dashboard?
