About five minutes. Alerts turn a dataset into something that tells you when to look. This tutorial adds a rule to the price tracker from the [previous tutorial](https://www.jsonify.com/docs/tutorials/price-monitoring) and sends it to Slack. The same steps work for any dataset and any channel. When a dataset publishes or a run finishes, each alert rule evaluates its condition. A match fires one alert that is delivered to the channels the rule selects: in-app, Slack, email, webhook or browser push. A rule evaluates on every publish and fires to the channels you pick. ## 1\. Connect Slack 1. **Create an incoming webhook in Slack.** In Slack, open the channel you want alerts in and add an _Incoming Webhook_ app to it. Copy the webhook URL. 2. **Add the integration in Jsonify.** Open **Integrations → Add integration → Slack**, paste the webhook URL and give the integration a name such as `#market-radar-alerts`. 3. **Test it.** Use the test action on the integration; a message arrives in the channel within a few seconds. The integration shows as connected. ![Integrations page with a connected Slack integration named market-radar-alerts](/assets/images/product/tut-slack-integration.png) A connected Slack channel. One integration can serve many rules. > The webhook URL is a secret. Anyone with it can post to your channel. Keep it in the integration only. ## 2\. Write the rule 1. **Open Alert Rules → New alert rule.** 2. **Describe the condition.** Either pick a quick-start chip or describe what you want. Jason proposes the rule; you confirm it. > Alert me when a product’s current price is at least 10% below its previous price in the Live product offers dataset. 3. **Choose the channels.** Tick **In-app** and the Slack integration you connected. Add email if you want a copy. 4. **Confirm.** The rule appears as a card with its toggle on. ![Alert Rules page with the Meaningful price drops rule card showing severity, condition summary and Slack channel](/assets/images/product/tut-slack-rule.png) The rule as a card. Toggle it off any time without deleting it. ## 3\. See it fire The rule evaluates the next time the dataset publishes. When it matches, one alert is created per event: it appears on the **Alerts** page and the bell badge, and the Slack message lands in the channel with a link back to the rows that triggered it. ![Alerts page showing a fired alert for 18,420 meaningful price drops with time, channel and rule](/assets/images/product/tut-slack-alert.png) The alert as it appears in Jsonify. What the Slack message looks like: > **Meaningful price drops** · Market Radar Prices fell by at least 10% across 18,420 tracked offers. Top: Sony WH-1000XM6 (Amazon) $348 → $279. Open the rows → ## Variations * **Run failures.** “Tell me in Slack when any pipeline in this workspace fails.” Useful for hearing about escalated repairs. * **New items.** “Alert when a new product appears in the catalogue.” * **A specific value.** “Alert when any product from Apple goes out of stock at Best Buy.” * **Jason’s judgement.** “Alert when a promotion looks like a clearance.” Jason evaluates each new row against the description.
