slack_webhook) integration for sending alerts directly to a Slack channel, and a Generic Webhook (webhook) integration for sending alerts to any HTTPS endpoint. These integration types appear on each entry in the Cloud Console Alert history page alongside the subject, delivery status, and timestamp.
Slack webhook integration
As an alternative to the OAuth flow, you can connect CoreWeave Alerts to Slack using an incoming webhook URL.Prerequisites
- The Notifications Admin IAM role, assigned through an IAM Access Policy.
- A Slack incoming webhook URL. To create one, follow Slack’s Sending messages using incoming webhooks guide.
Create a Slack webhook integration
- Log in to the CoreWeave Cloud Console.
- From the left navigation menu, select Administration > Integrations, or go directly to the Integrations page.
- In the Slack section, click Create Slack.
- Select the Slack webhook button.
- In the Display name field, enter a recognizable name (for example,
Cluster-Alerts-Webhook). - In the Slack Webhook URL field, enter your Slack incoming webhook URL. The URL must begin with
https://hooks.slack.com/services/. - Click Create integration.
Test the Slack webhook integration
- On the Cloud Console Integrations page, find the Slack Webhook integration you created.
- Locate the vertical ellipsis icon on the right side of the integration row. Expand the menu and click Send test. A success message appears in the lower right corner of the Cloud Console.
- In Slack, verify that the test notification message appears in your channel.
- Open the Alert history page. Confirm that the test alert appears with the correct subject, a Delivered status, the
slack_webhookintegration type, and a recent timestamp.
Generic webhook integration
You can send CoreWeave Alerts to any HTTPS endpoint using a generic webhook integration. This is useful for connecting to third-party tools, custom dashboards, or internal services.Prerequisites

Verify webhook signatures
If you configured a signing secret, CoreWeave sends anX-CoreWeave-Signature header with each webhook request. Use this header to verify that incoming requests are authentic.
