How to use OAuth2 in my application

[gek0n]

I want to get some information about my repositories from "Bitbucket REST API". I can do the trick with publick repos, but to working with private repos i need to be authorized.

I read Bitbucket OAuth Docs and create my first OAuth consumer: it has SECRET and KEY.
But i does not understand what a callback URL i must specify (if i have no server in internet).
And how i can use REST API with this KEY and SECRET?

I does not understand how i can authorize with them.
I tried somesthing like 

https://bitbucket.org/site/oauth2/authorize?client_id={KEY}

but it's not right way. Nothing happened.

How i can authorize to use REST API?

Honestly, it seems that you don't know what Oauth is. You'd probably should just authenticated with basic auth.
