Help posting an announcement through the API?

[david_joyner]

Hi!

I'm working on a script that can post announcements through the Canvas API. I've worked with the API a good bit before, but never with discussion topics, and I'm running into a 422 error.

I'm attempting to create the topic with a call to

PUT /api/v1/courses/123/discussion_topics‍‍

...with three parameters:

{"title": "Hello World", "message": "hello world", "is_announcement": "true"}‍‍

However, I'm getting a 422 error with that, and I'm not sure why; I'm guessing there's a required parameter I'm not passing, but I don't know which it would be. Never mind, it's not that as I could post with just course ID and message from the live API.

The discussion topics documentation says that is_announcement "requires announcment[sic]-posting permissions." Do you have those?

I do, my account is an instructor for the section.

Topic creation should be a POST, not a PUT.

I tell my CS students that the longer it takes you to find an error, the easier it is to fix once you find it.

I'm glad to be able to demonstrate that to them, too. That was it, thanks Peter!
