**Methods:**

#### `anotify` <sup>[https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L55](https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L55)</sup>

```python theme={null}
anotify(self, body: str, subject: str | None = None) -> None
```

#### `block_initialization` <sup>[https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L52](https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L52)</sup>

**Returns:**

* The run logger or a default logger with the class's name.

Context manager that, while active, causes the block to raise errors if it
encounters a failure sending notifications.

### `AppriseNotificationBlock` <sup>[https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L101](https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L101)</sup>

A base class for sending notifications using Apprise, through webhook URLs.

**Methods:**

#### `anotify` <sup>[https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L120](https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L120)</sup>

```python theme={null}
anotify(self, body: str, subject: str | None = None) -> None
```

```

### `SlackWebhook` <sup>[https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L154](https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L154)</sup>

Enables sending notifications via a provided Slack webhook.

Supports both standard Slack webhooks (hooks.slack.com) and Slack GovCloud
webhooks (hooks.slack-gov.com).

**Examples:**

Load a saved Slack webhook and send a message:

```python theme={null}
from prefect.blocks.notifications import SlackWebhook

slack_webhook_block = SlackWebhook.load("BLOCK_NAME")
slack_webhook_block.notify("Hello from Prefect!")
```

**Methods:**

#### `anotify` <sup>[https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L120](https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L120)</sup>

```python theme={null}
anotify(self, body: str, subject: str | None = None) -> None
```

#### `block_initialization` <sup>[https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L194](https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L194)</sup>

```python theme={null}
block_initialization(self) -> None
```

Initialize the Slack webhook client.

This method handles both standard Slack webhooks and Slack GovCloud webhooks.
Apprise's built-in Slack plugin only supports hooks.slack.com, so we need to
manually construct the NotifySlack instance for slack-gov.com URLs to ensure
notifications are sent to the correct host.

See: [https://github.com/caronc/apprise/issues/XXXX](https://github.com/caronc/apprise/issues/XXXX) (upstream issue)

#### `notify` <sup>[https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L136](https://github.com/PrefectHQ/prefect/blob/main/src/prefect/blocks/notifications.py#L136)</sup>

Enables sending notifications via a provided PagerDuty webhook.
See [Apprise notify\_pagerduty docs](https://github.com/caronc/apprise/wiki/Notify_pagerduty)
for more info on formatting the URL.

**Examples:**

webhook url, so we need to update the url and restart the client.
