Hiding Assignment Grades with the API

[aday]

With the removal of 'Muted' from assignments back in June/July how would you now create an assignment with the api with the grades hidden by default. Then at a later date make them visible.

Thanks,

You should be able to hide the grades by including "post_manually": true to your creation post.

This should set the posting policy for the assignment to manual meaning they will not be published until this is done manually.

See https://canvas.instructure.com/doc/api/assignments.html --> An Assignment object looks like --> third from bottom

 // Whether the assignment has manual posting enabled. Only relevant for courses
  // using New Gradebook.
  "post_manually": true,

I have tried setting that and it looks to be read only, the api documentation does not list it for create/edit

This needs to be set in the Gradebook (https://community.canvaslms.com/t5/Instructor-Guide/How-do-I-select-a-grade-posting-policy-for-an-as...) and assignments created afterward will automatically be hidden until the instructor posts grades for the specific assignment. Unfortunately, there doesn't seem to be anything in the API docs for setting it.
