26B: Marking EVENTS as complete using REST API

Summary:

Marking EVENTS or Redwood Course or Self-paced Learning as complete using REST API

Content (please ensure you mask any confidential information):

We are currently developing a custom Oracle APEX application to manage complex testing and grading rules for post-training evaluations for a very large county in Georgia. While we can successfully retrieve all learning assignments using the REST API, we have been unable to find an endpoint that allows us to mark a redwood learning record (specially an EVENT) as complete. Could someone point us to the correct API or payload structure required to update assignment completion statuses?
