Data direction: This is a destination — Upstack sends event and conversion data out to this platform via server-side APIs.

​
What it does

The Slack destination sends real-time notifications to any Slack channel when events occur on your store. Get instant alerts for purchases, new leads, abandoned carts, or any custom event — delivered directly to your team’s Slack workspace. Unlike ad platform destinations that optimize campaigns, Slack notifications are designed for visibility. See every high-value conversion the moment it happens, celebrate wins with your team, or monitor for unusual activity.

​
How it works

When a matching event occurs, Upstack:
  1. Evaluates the event against your configured event templates and conditions.
  2. Renders a Block Kit message using the template’s placeholder values (order ID, customer email, revenue, etc.).
  3. POSTs the formatted message to your Slack webhook URL.
  4. Logs the delivery status to the Upstack event debugger.
Each event template can have its own conditions — for example, only notify on purchases over $100, or only alert when a specific product is purchased.

​
Supported events

Slack notifications can be triggered by any standard or custom event:

PurchaseCelebrate new orders, track high-value conversions

Setup instructions

​
Step 1: Create a Slack Incoming Webhook

  1. Go to Slack API Apps and click Create New App.
  2. Choose From scratch, name your app (e.g., “Upstack Notifications”), and select your workspace.
  3. Under Features, click Incoming Webhooks and toggle it On.
  4. Click Add New Webhook to Workspace and select the channel where notifications should appear.
  5. Copy the Webhook URL — it looks like https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX.

​
Step 2: Configure the Slack destination in Upstack

  1. In the Upstack dashboard, go to Destinations and click Add Destination.
  2. Select Slack from the destination list.
  3. Paste your Webhook URL from Step 1.
  4. Create one or more Event Templates to define which events trigger notifications and how they’re formatted.

​
Step 3: Create event templates

Each template maps a source event to a Slack message:
  • Source Event: The event type that triggers this template (e.g., Purchase).
  • Template: The Block Kit message structure with placeholders like {{data.order_id}} and {{data.value}}.
  • Conditions (optional): Filter criteria — only send when conditions are met.

​
Example message format

Slack messages use Block Kit for rich formatting. Here’s an example purchase notification: 
{
  "blocks": [
    {
      "type": "header",
      "text": {
        "type": "plain_text",
        "text": "🎉 New Purchase!"
      }
    },
    {
      "type": "section",
      "fields": [
        {
          "type": "mrkdwn",
          "text": "*Order ID:*\n{{data.order_id}}"
        },
        {
          "type": "mrkdwn",
          "text": "*Revenue:*\n${{data.value}}"
        },
        {
          "type": "mrkdwn",
          "text": "*Customer:*\n{{data.email}}"
        },
        {
          "type": "mrkdwn",
          "text": "*Source:*\n{{context.utm_source}}"
        }
      ]
    },
    {
      "type": "context",
      "elements": [
        {
          "type": "mrkdwn",
          "text": "via Upstack Data"
        }
      ]
    }
  ]
}
Placeholders like {{data.order_id}} are replaced with actual event values at send time.

FAQ

Create an Incoming Webhook in your Slack workspace settings. Go to Slack API Apps, create or select an app, enable Incoming Webhooks, and add a new webhook to your desired channel. The URL is generated automatically.
Each Slack destination has one webhook URL (one channel). To send to multiple channels, create multiple Slack destinations with different webhook URLs and configure each with the appropriate event templates.
Conditions let you filter which events trigger a notification. For example, you can configure a template to only fire when data.value is greater than 100, or when data.currency equals “USD”. Conditions support AND/OR logic for complex filtering.
Any field from the tracking event is available as a placeholder. Common examples:
  • {{data.order_id}} — Order ID
  • {{data.value}} — Order value
  • {{data.email}} — Customer email
  • {{data.currency}} — Currency code
  • {{context.utm_source}} — UTM source
  • {{context.page_url}} — Page URL where event occurred
Failed deliveries are logged to the Upstack event debugger. Upstack uses SQS-based retry with exponential backoff for transient failures. If the webhook URL is invalid or the Slack app is deleted, events will fail permanently and appear in your delivery logs.
