Google Classroom API create a link to the course - hyperlink

Question

I am developing an agenda for my students. They are enrolled in different classes and have different courses in Google Classroom.
I am able to get the Classroom courses id, and get the grades. But I can not find information about how to link from my agenda to the course. Can I use the course id to create a link to the classroom course?
For example, if I get the courses list like this:
12012929120
12129399390
10101303003
Is there anyway to create a URL to go directly to that course? (For example: https://classroom.google.com/id/12012929120)
Or is any other way to retrieve my courses from the API and create links to my courses?

Answer 1

I'm pretty sure you can form a url like:
https://classroom.google.com/c/
So if you id was 12012929120 the url might be:
https://classroom.google.com/c/MTIwMTI5MjkxMjA=
But I just know that via experimentation with my own course so I can't guarantee that will always work. I couldn't find any docs to answer the question definitively when I was trying to figure it out for myself.

Answer 2

From the document, upon creating a classroom using Method: courses.create if the creation is successful the return value of this method is the classroom resource object which includes the alternateLink:
{
"id": string,
"name": string,
"section": string,
"descriptionHeading": string,
"description": string,
"room": string,
"ownerId": string,
"creationTime": string,
"updateTime": string,
"enrollmentCode": string,
"courseState": enum(CourseState),
"alternateLink": string,
"teacherGroupEmail": string,
"courseGroupEmail": string,
"teacherFolder": {
object(DriveFolder)
},
"courseMaterialSets": [
{
object(CourseMaterialSet)
}
],
"guardiansEnabled": boolean,
}
You can use the alternateLink to pass as a hyperlink for your classroom.
Hope this helps.
