Classes Overview

By Jaron Pate

Last Updated October 8th, 2025

A Class is an instance of a Course. Many People can be Enrolled in a Class.

Classes typically define a specific time period (e.g., semester, quarter) during which the course is taught.

In previous versions of the Edlink API, this concept was called a Course. Please review Migration from v1.0 for more information.

In v2.0, we've corrected some of our terminology to be more accurate and universal.

Notes

The subjects and periods properties have been deprecated in favor of the new Subject and Period models.
- The old properties will still be supported through the lifespan of API V2, but they may not be as accurate as the new models.
The new subject_id property is singular.
When you use the $expand operator on periods, the result will override the deprecated periods property.
