# Notifications

> Manage in-app, email, Slack DM, and Discord DM notification delivery.

Use this page to check notification categories, delivery channels, and Slack or Discord account linking.

## Notification center

Custory includes an in-app notification center accessible from the notification bell.

The notification center is split into:

* Inbox
* Archive

From the notification center, you can:

* open related work directly
* mark notifications as read
* mark notifications as unread
* mark all inbox items as read
* archive items
* move archived items back to inbox

## Notification categories

| Category     | Includes                                                                                                                              |

| Item updates | Changes on items assigned to you, including comments, assignment changes, and status changes.                                         |
| System       | Invitation updates, join requests, automation failures, invalid automations, integration errors or expiry, and external task changes. |

## Delivery channels

Custory supports these delivery channels:

* in-app
* email
* Slack DM
* Discord DM

Each category can use one or more supported channels.

## Slack and Discord DMs

Notification delivery happens at two levels:

* the workspace must have the Slack or Discord [integration](/integrations) connected
* each person must link their own Slack or Discord identity

### Slack DM setup

Slack DM delivery requires:

1. an active Slack workspace integration
2. your Slack account linked to your Custory account

From **Settings -> Notifications**:

1. generate a Slack link code
2. open the Custory app in Slack
3. send the generated code, or `link CODE`, in the **Messages** tab

### Discord DM setup

Discord DM delivery also requires:

1. an active Discord workspace integration
2. your Discord identity linked to your Custory account

From **Settings -> Notifications**:

1. generate a Discord link code
2. open a DM with the Custory bot in Discord
3. run `/link CODE`

## Link code behavior

Custory link codes are intentionally temporary.

Current behavior:

* codes expire after 15 minutes
* a code can only be used once
* you can regenerate a code
* you can clear an unused code
* you can unlink an already linked Slack or Discord account

## Troubleshooting

* If Slack or Discord DMs do not arrive, confirm both the workspace integration and the personal account link.
* If a link code fails, generate a new one. Codes are temporary and single-use.
* If a system notification depends on an integration, confirm that integration is active.
