Need Canvas LMS API Consultant - Grade Passback Integration

[JosephWright234]

Problem:

Looking for help with Canvas LMS API integration for automated grade synchronization from our external assessment platform. We're using the Submissions API to post grades, but getting inconsistent results - some scores update correctly while others fail silently.

The OAuth authentication works fine and we can retrieve assignment data, but grade submissions return 200 responses without actually updating student grades. Need someone experienced with Canvas API and gradebook integration patterns.

Seeking 2-3 hours remote debugging to resolve the grade passback reliability issues. Critical deadline - need working by Monday for midterm grade imports.

Hi @JosephWright234,

I'm going to move your post over to the Developers Group, where experts in this area are more likely to see the post.

I do have one initial clarification question for you that will probably be helpful for others too...  I think you're trying to get grades from another system into Canvas, correct?  Or is it the other way around where you're trying to get info out of Canvas and saved into another system?
