Slack Notifications

Send automated messages to Slack channels when events occur using the CONNECTOR step type.

What You'll Build

An automation that:

1. Receives new order data via webhook trigger
2. Uses CONNECTOR step to post to Slack
3. Uses CONDITION step to route high-value orders to VIP channel

Step 1: Connect Slack

Create a Slack Connection

1. Go to Connections
2. Click + New Connection
3. Search for Slack connector
4. Click Connect

Authorize work.studio

1. A Slack popup opens
2. Select your workspace
3. Click Allow
4. The popup closes — you're connected!

Step 2: Create the Automation

1. Go to Automations
2. Click + New Automation
3. Name: New Order Slack Alert
4. Click Create

Step 3: Add Webhook Trigger

Configure Trigger

1. Click Add Trigger
2. Select Webhook
3. Copy the webhook URL

Expected Payload

{
  "order_id": "ORD-12345",
  "customer": "Acme Corp",
  "amount": 499.99,
  "items": ["Widget Pro", "Widget Basic"]
}

Step 4: Add CONNECTOR Step for Slack

Add the Step

1. Click + below the trigger
2. Select CONNECTOR from the step palette

Configure the Connector Step

Configure Parameters

Message Template

🎉 *New Order Received!*

*Order ID:* {{ input.order_id }}
*Customer:* {{ input.customer }}
*Amount:* ${{ input.amount }}

*Items:*
{{ input.items.join(", ") }}

Step 5: Add CONDITION for High-Value Orders

Add CONDITION Step

For large orders, send an additional alert to a VIP channel:

1. Click + after the Slack CONNECTOR step
2. Select CONDITION from the step palette
3. Name it: Check High Value

Configure the Condition

{{ input.amount }} > 1000

True Branch: VIP Alert

In the "True" branch, add another CONNECTOR step:

Your workflow now looks like:

┌─────────────────────┐
│  Webhook Trigger    │
└──────────┬──────────┘
           │
           ▼
┌─────────────────────┐
│  CONNECTOR: Slack   │
│  Post to #orders    │
└──────────┬──────────┘
           │
           ▼
┌─────────────────────┐
│  CONDITION          │
│  amount > 1000?     │
├──────────┬──────────┤
│ True     │   False  │
└────┬─────┴────┬─────┘
     │          │
     ▼          ▼
┌─────────┐   (end)
│CONNECTOR│
│#vip-orders│
└─────────┘

Step 6: Test the Integration

Save and Activate

1. Click Save
2. Toggle Active

Send Test Webhook

Use curl or any HTTP client:

curl -X POST api.work.studio/webhook/YOUR_WEBHOOK_ID \
  -H "Content-Type: application/json" \
  -d '{
    "order_id": "ORD-99999",
    "customer": "Test Corp",
    "amount": 1500.00,
    "items": ["Premium Widget", "Deluxe Addon"]
  }'

Verify in Slack

Check both channels:

• #orders — Should have the order notification
• #vip-orders — Should have the high-value alert (amount > 1000)

Advanced: Using Block Kit

For rich interactive messages, use Slack's Block Kit format:

CONNECTOR Configuration with Blocks

Set the blocks parameter instead of text:

[
  {
    "type": "section",
    "text": {
      "type": "mrkdwn",
      "text": "🎉 *New Order: {{ input.order_id }}*"
    }
  },
  {
    "type": "section",
    "fields": [
      {"type": "mrkdwn", "text": "*Customer:*\n{{ input.customer }}"},
      {"type": "mrkdwn", "text": "*Amount:*\n${{ input.amount }}"}
    ]
  },
  {
    "type": "actions",
    "elements": [
      {
        "type": "button",
        "text": {"type": "plain_text", "text": "View Order"},
        "url": "flow.work.studio/orders/{{ input.order_id }}"
      }
    ]
  }
]

Using Slack as a Trigger

You can also trigger automations FROM Slack using the Slack trigger type:

1. Create a new automation
2. Click Add Trigger → Slack
3. Configure:
   • Channel to monitor
   • Message pattern or slash command

When someone posts in that channel (or uses the command), your automation runs.
