Create a Slack notifier

To create a Slack notifier, generate an incoming webhook in Slack and then create a Slack notifier in Chronosphere Observability Platform.

Create an incoming webhook in Slack

Before creating a Slack notifier in Observability Platform, create an incoming webhook in Slack. See Sending messages using incoming webhooks (opens in a new tab) in the Slack documentation for more information.

After creating an incoming webhook in Slack, you can create a Slack notifier in Observability Platform. You can use variables in your notifiers.

To create a Slack notifier:

In the navigation menu select Alerts > Notifiers.
Click Create notifier.
Enter a descriptive name for the notifier.
Select Slack as the type of notifier you want to create.
In the API URL field, enter the URL you created for your webhook in Slack, which is called as a POST request. For example:
```
https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXX
```
The API URL (opens in a new tab) from Slack contains the channel name.
The Channel field is deprecated and doesn’t affect the notifier. A channel name is still required in this field until the field is fully removed.
Optional: In the Username field, enter the Slack username to post the notifier as.
Optional: Select Notify when resolved to send a resolved alert notification.
Click Save.
