Creating a custom gradebook column

[rancho]

I am brand new to the canvas api, but not apis.  This is not supposed to be hard, but I am stumped again.  I am trying to create a custom grade book column.  Here is the url I am trying to use on a POST

https://{my institution}.test.instructure.com/api/v1/courses/{my course id}/custom_gradebook_columns

Here is the json I am posting

{"teacher_notes":false,"title":"StudentsEmployees","position":0,"hidden":false,"read_only":true}

And here is my response from the api

{

    "errors": [

        {

            "message": "column is missing"

        }

    ]

}

It almost is acting like I am trying to do a put and modify a custom column, but

I am not, I am doing a post.

Another thing is for this course on the grade book there is a grid, with the students

names in a column and then what looks like assignments in other columns. But when I

use the same url with a get all I get is an empty array. Is that because those

columns are not custom?

Thanks for reading this far.

Hi,

you must include the "column" key in the json, like this:

{
   "column": {
      "title": "StudentsEmployees",
      "read_only": true
   }
}

Duh it was exactly as the error message was telling me.  Thank you so much.  I really appreciate it.
