# Overview

# Case Events service overview

The Case Events service manages the events that appear on a case's Activity timeline. Use it to list the events on a case, retrieve a single event by ID, and create, update, or delete comment events on a case. The service also exposes a sync endpoint that lets Coralogix Cases pull comments from external systems (for example, Slack) into the case timeline.

Learn more in our [documentation](https://coralogix.com/docs/user-guides/cases/working-with-cases/#activity-tab).

## Authentication and permissions

To use the Case Events service API you need to [create a personal or team API key](https://coralogix.com/docs/user-guides/account-management/api-keys/api-keys/). Cases do not ship with a permission preset; add the individual `case:*` permissions you need.

| Presets | Permission | Description |
| - | - | - |
| | `case:Read` | List events for a case and retrieve a single event by ID. |
| | `case:Comment` | Create, update, or delete a comment event, and sync events from an external system into the case timeline. |

## Common error response codes
