using the canvas API as a student for announcements

[TheVaccine]

quick note: I am a student.

I want to be able to get canvas announcement notifications for my classes into a discord server I am in. So, I am currently trying to find a way to use the API to get a list of notifications in json or html format so I can pass that along to a discord bot I made to send them to my discord server. 

a quick google search for the canvas api led to to this page: Announcements - Canvas LMS REST API Documentation (instructure.com)

So, I tried using the example request they gave at the bottom to get some response but whenever I run the curl command in a linux terminal, nothing happens. I ran curl with "-v" and it shows that I got a http 200 code so it should be working but I get no output after running the command without the "-v"

here is what I ran:
curl 'https://canvas.vt.edu/api/v1/announcements?context_codes[]=course_119111&access_token=mytoken'

^ I replaced mytoken with the token from generating a token in my user profile settings whithin canvas. 

Every time I tried using the authorization bearer thing from the documentation, i get an error in curl so i did not include that part. 

what do i need to do to get the output of a list of announcements for my class into the terminal?

I realize how late this is but I ran into the same issue while trying to create my own discord bot. What worked for me was adding the start_date and end_date parameters. By default, according to the API documentation, it assumes that the start date is 14 days ago and the end date is 28 days after the start. Most of the time this will not encompass all of the announcements, or even any of them, which might have been why you were getting no output. A good start date that is always available as far as I know is the creation date of the course, and a good end date is the current date. Both should be formatted as YYYY-MM-DD or according to the ISO 8601 YYYY-MM-DDTHH:MM:SSZ format. As an example of what might work:

curl 'https://canvas.vt.edu/api/v1/announcements?context_codes[]=course_<id>&access_token=<access token>&start_date=<course creation date>&end_date=<current date>'

Replace everything inside <> with the corresponding values.

Hope this helps.
