Do I need to create a website to make an app on Codechef?

Hello all,

This may be a silly question, but when I want to create a test app on Codechef API, it asks me for a website URL and a redirect URL. But I can’t just put a random URL. I tried putting a few, the system marks them as invalid.

All I want to do right now is to do a few queries and view their JSON outputs. Can someone please help?


Update: Problem solved. I just needed to add https:// before my url to get it accepted. For all those who are struggling, please use the format https://.com and it will get accepted


To implement OAuth2 you will need a server side verification.
Use alibaba resources to implement that.

For testing on your machine you can use .
