Adding custom fields to student records in a single course

[matt_price]

I generally store a couple of extra pieces of information about my students in my local student records.  Usually these are things like:

• Github ID
• nickname
• identifying story or "fun fact" that students fill out early on (I use this as a mnemonic device to get to know my students)

Is there a way for me to store this information in Canvas, in a way that is accessible via the API? RIght now I have to store it separately and then merge my datasets whenever I want to have access to everything (since students can drop out for most of the semester here, I have to keep updating the database before  I send out marks).

I'm asking not as an admin but as a teacher, so I'm looking for a solution that's in htat authorization scope. 

Thanks everyone!

The first two might fit nicely in a Custom Gradebook Columns - Canvas LMS REST API Documentation 

The third might be a bit big.

I've only tried custom columns as an admin, but as it is the course gradebook you would hope they work for a teacher.

Just checked with a teacher token and it worked fine.

Thanks Peter, this is great. I was able to create the columns no problem.  Now I am trying to post data back to them using hte bulk update endpoint. I have a json file that looks like this:

{"column_data" : [
  {
    "content": null,
    "user_id": 100120,
    "column_id": 721
  },
  {
    "content": "is",
    "user_id": 100120,
    "column_id": 723
  }
]}

And I try this curl command:

 curl -X PUT  -d @/home/matt/example.json  -H 'Authorization: Bearer API-SECRET'  "https://uni.baseurl/api/v1/courses/64706/custom_gradebook_columns_data"  --header "Content-Type: application/json"

But I'm getting back a 400 response.  Can you spot an error in my JSON maybe?

Many thanks in any case!

The URL is wrong, it should have ...column_data (no 's').
