# Notifications

> What CanvasView tells you about your account, and how to read, filter and dismiss notifications.

CanvasView sends a notification when something about your organization needs attention. Every member and every agent in the organization sees the same notifications. The bell in the header shows how many are unread. Select it to see the latest, or open [Notifications](https://app.canvasview.dev/notifications) for the full list.

## What you are told about

| Notification | Severity | When |
| - | - | - |
| An agent asked for a data source | Action | An agent asked you to approve a [data source](https://docs.canvasview.dev/account/data-sources.md). Asking again with the same name updates the notification and marks it unread. |
| Data source removed while canvases use it | Warning | You removed a data source that live canvases still declare. It names those canvases. |
| Your webhook was switched off | Warning | CanvasView could not deliver events to your [webhook](https://docs.canvasview.dev/developers/events-and-webhooks.md) for a day and stopped sending them. |
| A canvas now needs sign-in | Info | A link-access canvas started using a data source, so CanvasView switched it to sign-in. See [Sharing and access](https://docs.canvasview.dev/account/sharing-and-access.md#canvases-that-use-a-data-source). |
| A canvas tool is failing | Warning | A [tool](https://docs.canvasview.dev/developers/custom-components.md#canvas-tools) on one of your canvases keeps failing. Open the canvas, or ask your agent to fix the tool. |
| CanvasView removed a canvas | Warning | CanvasView removed a canvas after a report. Its link no longer works. |
| Message from CanvasView | Varies | CanvasView wrote to you about your account. |

Notifications carry titles and plain text written by CanvasView. They can quote names an agent chose, such as a canvas title, but never a canvas's content.

## Severity

* **Action needed** means someone needs to do something. Actions stay at the top, under **Needs you**, until an Admin dismisses them or they are resolved.
* **Warning** means something stopped working or changed.
* **Info** tells you about a change you may want to check.

Some notifications clear themselves when the condition goes away. Approving or dismissing a data source request clears its notification. Saving the webhook endpoint again clears the webhook warning.

## Read and dismiss

Every member can read notifications. Only Admins can mark them read or dismiss them.

* Select **Open** to go to the page the notification is about.
* Admins can select **Mark read**, or **Mark all read**.
* Admins can select **Dismiss** to remove a notification from the list.
* Use the filters to show unread notifications or one severity.

Notifications are kept for 90 days, and an account keeps up to 200.

## Agents and notifications

Your agents can read your notifications with `list_notifications`. For example, an agent can learn that a data source it needs was removed, or that its data source request is still waiting. Agents cannot mark notifications read or dismiss them. Only Admins can.
