Slack Integration: Notify Your Team from WordPress Automatically

Posted
Byaiadmin

After this setup, your AIWU workflows will post messages to Slack channels automatically — notifying your team about new orders, form submissions, AI-generated content, or any WordPress event you choose.

In this article: Connect Slack · Slack Actions · Order Notification Example · Common Issues

Before You Start

You’ll need:

  • AIWU plugin v4.9+ installed
  • A working knowledge of AIWU Workflows — build your first workflow first
  • A Slack workspace where you have admin access (or permission to add apps)
  • Time needed: ~10 minutes

Step 1: Create a Slack App and Get a Webhook URL

1a. Create a Slack App

Go to api.slack.com/apps → Create New App → From scratch.

Name your app “AIWU Notifications”. Select your workspace. Click Create App.

1b. Enable Incoming Webhooks

In your app settings, go to Incoming Webhooks → toggle ON.

Click Add New Webhook to Workspace. Select the channel where you want notifications. Click Allow.

What you should see: A Webhook URL like https://hooks.slack.com/services/T.../B.../xxx. Copy it.

💡 Tip: Create separate Slack apps (or webhooks) for different channels — one for orders, one for support, one for content publishing.

Step 2: Add Slack Webhook to AIWU

Go to WordPress Admin → AI Copilot → Settings → Integrations → Slack.

Paste your Webhook URL. Give it a name (e.g., “Orders channel”). Click Save & Test.

What you should see: A test message appears in your selected Slack channel within a few seconds.

✅ Connected! You’ll see a test message in your Slack channel.

Step 3: Using Slack in Workflows

Open any workflow and click Add Action → Send Slack Message.

Slack Action Fields

Field Description Example
Webhook Select your saved connection “Orders channel”
Message Text to send — supports variables and emoji 🛒 New order #{{order_id}} from {{billing_first_name}}
Rich Format Optional: structured blocks with fields Order details in a formatted card

Formatting Tips

  • Use *bold* for important info
  • Use n for line breaks
  • Emoji work natively: ✅ 🛒 🚨
  • All workflow variables work: {{order_total}}, {{post_title}}, {{user_email}}

Practical Example: WooCommerce Order → Slack Notification

This workflow posts to Slack every time a new WooCommerce order comes in:

  1. Trigger: WooCommerce New Order
  2. Action 1: Generate Text — “Write a 1-sentence summary of this order: Items: {{order_items}}, Total: {{order_total}}, Customer: {{billing_first_name}} {{billing_last_name}}”
  3. Action 2: Send Slack Message 
    🛒 *New Order #{{order_id}}*
Customer: {{billing_first_name}} {{billing_last_name}}
Total: ${{order_total}}
{{generated_text}}
👉 View order: {{order_admin_url}}

See the full recipe: WooCommerce Order Notifications.

Another Example: New Review → AI Response → Slack

A workflow that gets an AI response to a new product review, then posts both to Slack for team approval before publishing:

  1. Trigger: WooCommerce Review Submitted
  2. Action 1: Generate Text — “Write a professional, empathetic 2-sentence response to this review: {{review_content}}”
  3. Action 2: Send Slack — “📝 New review on {{product_name}}:n*Review:* {{review_content}}n*Draft AI response:* {{generated_text}}nApprove and post? {{review_admin_url}}”

Verify It Works

  1. Trigger your workflow manually using the Test Run button.
  2. Check the target Slack channel — your message should appear within 5 seconds.
  3. In AIWU, go to Workflows → [workflow] → Logs — look for a green “Success” status on the Slack action.

Common Issues

Problem: “Error: invalid_payload” in workflow logs.
Fix: The message contains a special character or unclosed variable. Check for {{}} placeholders that weren’t replaced — this happens when a variable name is misspelled.

Problem: Slack shows the message but formatting looks wrong (asterisks visible).
Fix: Make sure your message text doesn’t wrap the bold markers in quotes or HTML tags. Slack’s mrkdwn format uses *text* not **text**.

Problem: Webhook URL stopped working after a while.
Fix: Slack webhooks are permanent, but apps can be revoked by workspace admins. Go to api.slack.com/apps → [your app] → Incoming Webhooks and verify the webhook is still active. Re-add if needed.

Problem: Messages come through but the wrong channel.
Fix: Webhook URLs are channel-specific. If you moved the app to a different channel in Slack, generate a new webhook URL and update it in AIWU settings.
