Welcome to Android Central forums.
We may need more information to in order to help you but I did a simple internet search and found information on OAuth-Redirect but nothing on the terms you offered. Is it possible that there is a typo in your post?
I found this in formation at the top of the list.
What is OAuth redirect?
The redirect URL is the endpoint for your application or web page that processes the seller authorization response and manages the seller's OAuth tokens. You need to add this URL to your application using the Developer Dashboard.
If you would like to look into it more this is the link.
