Google Chat

A Google Chat channel type posts each alert as a message in one Chat space, through the space's incoming webhook. Create the webhook in the space, paste its URL into CentralCSP, send a test.

Prerequisites

• The website Manager role in CentralCSP.
• A Google Workspace account. Webhooks are a Workspace feature; personal Google accounts cannot create them, and your organization must allow them.
• A Chat space you can manage.

1. Create the webhook in Google Chat

1. Open Google Chat in a browser and enter the space that should receive alerts.
2. Select the space name to open its menu, then Apps & integrations.
3. Select Add webhooks (under Webhooks).
4. Name it (for example CentralCSP alerts), optionally set an avatar URL, and select Save.
5. Open the webhook's More menu and select Copy link. The URL starts with https://chat.googleapis.com/v1/spaces/.

Google's own guide is at Build a Google Chat app as a webhook.

A webhook only posts to the space it was created in. Treat the URL as a secret; anyone holding it can post to the space.

2. Add the channel in CentralCSP

1. In the dashboard, go to Alerts > Configuration > Add channel.
2. Name the channel, choose the Google Chat type, and paste the webhook URL.
3. Save.

The URL is validated as you type: it must be on chat.googleapis.com with a path starting /v1/spaces/, so a space link or a chat page URL pasted by mistake is rejected before you save.

3. Test the channel

Select Test on the new channel. A sample alert built from a fake CSP violation is sent immediately.

If the message does not arrive, the webhook was refused. Check that the webhook still exists under Apps & integrations and that your organization still allows webhooks in that space; a deleted webhook fails permanently.

Next steps

• Create a rule that delivers to this channel.
• Channels overview for auto-disable behaviour and limits.
• Delivery history to audit what was sent.
