Getting a webhook URL
Create a Slack app
Go to api.slack.com/apps and create a new app in your workspace.
Enable incoming webhooks
Under Incoming Webhooks, turn the feature on.
Add it to a channel
Choose Add New Webhook to Workspace and pick the channel alerts should land in. Slack gives you a URL.
Paste it into Glowo
Create a Slack channel in Glowo with that URL, then use Test to confirm the message arrives.
Message format
Alerts arrive as formatted messages with the monitor name, the status change, and links back to Glowo — including acknowledge and pause actions.
Glowo uses Slack’s mrkdwn links rather than Block Kit buttons. Links render
consistently everywhere Slack messages are read, including notification
previews and mobile, where interactive blocks often do not.
Action track
Slack is one of three channels (with Discord and Telegram) that receive an inline follow-up when an alert is muted or reactivated, so the thread reflects what actually happened. Email, SMS, PagerDuty and webhook channels get no such message — a standalone “muted” email is noise when the alert itself already went out.
Practical notes
- One webhook per channel. To post to
#alertsand#platform, create two Glowo channels with two Slack webhooks. - Scope it. A workspace-wide Slack channel subscribed to every event on every monitor becomes background noise within a week. See scoping.
- Slack is for awareness, not for waking people. Pair it with SMS or PagerDuty for out-of-hours.
