Canvas Customization

[MaliniKrishnamu]

Hi 

I am trying to build a portal with a team of developers and we are interested in integrating a few features from the free for teachers Canvas account. 

We have designed an LMS and would like to have some functionalities from Canvas. So my 

Question : Is it possible to cherry pick some of the features in Canvas and integrate them in our portal site and customize the appearance?  

OR

Do we have to create a Canvas course on Canvas site and use a link to redirect users to the Canvas site from our portal.

We prefer the first option.

Any advise on this would be helpful. Thank you.
