Intergrate grading service

[haimeo1201]

Hi all!

I deployed canvas lms for my school. Previously we had a server for student to submit programming problem and return the score. I want to use canvas ui and student can just submit their code in the ui and return the results. Can i have some guidance how to do this? 

Thanks!

Sorry it is not clear to me what you are asking. 
What is an example of 'student submit the programming problem'?
What is an example of 'return the score'?

Sorry for took so long to reply.
So my school previously has developed a programing learning web app for students to submit their solutions in code (C++, python) and return the results for each test cases in a problem (WA, Correct, Time limit, ...).
Now we want to use canvas and would like students to seamlessly submit their solutions from canvas and get results back to canvas without having to log in the web app and teachers then have to manually get grades from that app.
Can you help me with some guidelines on how to do that? Thank you very much
