Hi, and welcome to the Feedly Cloud group!
In order to integrate with feedly's OAuth system, you need to provide a redirect_uri.
Here are the two default values you can use:
urn:ietf:wg:oauth:2.0:oob
If you need a different sandbox redirect_uri for your application, please send me an email:
da...@feedly.com.
Regards.
