Import data from dynamics CRM using REST API

Question

I am working on CRM Application to manage clients leads and tracking data's which is written in ruby on rails.

Now clients are asking me to pull existing leads from Microsoft Dynamics CRM which is already saved in their account.

But some of my clients not ready to share their login details with me.

So, I was planing to import data using API's. From last week and reading dynamics CRM documentation,but am not getting clear idea.

I tried below link

OAuth 2.0 with Dynamics CRM Online but am not able to create app in Microsoft Azure AD.

I wants solution like facebook authentication way.

Please share some documentation or suggest me some ideas.

Am Using: Rails 4, apache, Linux, dynamics CRM 2011 and 2013

I don't understand how you expect to connect without login credentials.

I don't see how you can be on version 2011 and 2013 at the same time.

Please share some documentation or suggest me some ideas.

Have a look at MSDN - Authenticate users with Microsoft Dynamics CRM web services, make sure you select the correct documentation version at the top of the page. You could try claims based authentication.
