How does OAuth work?

Question

I mean not how is it implemented but rather what steps should user pass?

I'm working with Photobucket now and I found in its docs that I should generate new token for every request due to token can expire in certain (but secret) period of time.

How does this generation works? Do I need separate request for generating token?

Answer 1

You can have a log in button, and when a user clicks on it you would make an ajax request to get a new oauth access token and then generate the oauth url based on that token.

Then after the user authenticates they will be redirected to a callback URL that you must specify from within your account settings.
