Google OAuth 2.0 redirect_uri_mismatch error

  1. I created a Google OAuth 2.0 ClientID and secret in Google Developer console

  2. After that I tested in Google OAuth playground (https://developers.google.com/oauthplayground). and registered ClientID and secret already created above and applied to Google OAuth 2.0 playground setting menu.

  3. Some people say that after creating ClientID/secret they need some time for testing. So after two days I tried to test in the same conditions but the error is same redirect_uri_mismatch.

How can I solve this?

As little as having a '/' at the end of your uri and not having the same '/' at the end in your code will throw it off.
