Nothing is sent to Slack until you save a valid webhook URL. Turning notifications On alone is not enough — Save is what makes delivery work. Send a test right after you save so you know the channel and URL are correct.
Setup
1
Turn on notifications here in Hilt
Start on the Integrations page and flip Slack notifications to On. That opens the setup panel where you’ll paste your webhook URL in a minute. Nothing is sent to Slack until you save a valid link, and we recommend sending a test afterwards to make sure it landed in the right place.
2
Go to Slack and create an app
You’ll need to be a Slack workspace admin for the next few steps, or ask someone who is. Open api.slack.com/apps in your browser. Click Create New App, choose From scratch, and give the app a name people will recognize on alerts, something like “Hilt Alerts”. Pick the workspace where your team lives and click Create App. If your company already has a Slack app for internal tools, you can reuse that one instead of making a new app.
3
Turn on incoming webhooks
In your new app, open Incoming Webhooks in the left sidebar and switch it on. This gives Hilt a private link it can use to post messages. There is no bot to install and nothing extra for your team to approve beyond the channel step coming next.
4
Connect the webhook to your channel
Click Add New Webhook to Workspace. Slack will ask you to pick a channel, so choose where you want anomaly alerts to show up, for example
#security-alerts. If that channel does not exist yet, create it in Slack first, then come back and pick it. Click Allow. Slack ties this one URL to that one channel, which is why Hilt does not ask you to type a channel name here.5
Copy the link Slack gives you
After you allow the channel, Slack shows a Webhook URL. It always starts with
https://hooks.slack.com/services/ followed by a long random path. Copy the whole thing and treat it like a password. Anyone with this link can post to your channel, so do not paste it into email or a public chat.6
Finish back here in Hilt
Come back to the Integrations page. Paste the URL into the Webhook URL field and click Save. If the URL is missing or does not look like a Slack webhook link, Save will not go through and we will tell you the link is not valid. Once Save succeeds, click Send test notification and check your Slack channel. When the test message shows up, you are done. Real anomaly alerts will start posting on their own within about thirty seconds of detection.
