## Introduction
In a fast-paced startup or growing business, ensuring your marketing team stays up to date with the latest customer journey stages in your CRM is crucial. Marketing strategies often depend on the current stage of a lead or customer—such as lead qualification, negotiation, or closing. Manual tracking wastes time and introduces errors, slowing down campaign responsiveness.
This article describes how to build an automation workflow to notify your marketing team instantly when a contact’s CRM stage changes. We’ll use n8n, an open-source and highly flexible automation tool, integrating your CRM (such as HubSpot or Salesforce), Slack, and optionally Google Sheets for logging.
### Who benefits?
– Marketing teams get real-time updates and can tailor communications or campaigns based on stage changes.
– Sales teams benefit indirectly as marketing aligns better with sales progress.
– Operations and automation engineers save time by eliminating manual status checks.

## Tools and Services
– **n8n**: Automation workflow tool hosting the integration
– **CRM system (HubSpot, Salesforce, or others supporting API/webhooks)**: Source of contact stage changes
– **Slack**: Channel for marketing notifications
– **(Optional) Google Sheets**: For logging and analytics
—
## Overview of the Workflow
**Trigger:** CRM emits a webhook or we poll CRM API for contact stage changes.
**Logic:** Check if the stage field has changed; retrieve relevant contact details.
**Action:** Send a detailed message to the marketing Slack channel.
**Optional:** Log the event in Google Sheets for records.

## Step-by-Step Technical Tutorial Using n8n
### Prerequisites
– Access to your CRM API with permissions
– Slack workspace and webhook URL or OAuth credentials
– An n8n instance (cloud or self-hosted)
– Optionally, a Google account with access to Sheets API
### Step 1: Create a New Workflow
1. Log into your n8n editor.
2. Create a new workflow and name it “CRM Stage Change to Marketing Notification.”
### Step 2: Set up the Trigger
#### Option A: Webhook Trigger (preferred if CRM supports webhooks)
1. Add a **Webhook** node to your workflow.
2. Configure the webhook with `POST` method.
3. Copy the webhook URL.
4. In your CRM dashboard, set up a webhook subscription for the ‘Contact Stage Changed’ event, pointing to the copied URL.
#### Option B: Polling CRM API
1. Add a **Cron** node to trigger checks periodically (e.g., every 5 minutes).
2. Add a **HTTP Request** node to query contacts whose stages recently changed using CRM API filters.
### Step 3: Process the Incoming Data
1. Add a **Function** node to extract and verify the stage change event from the webhook payload or API response.
2. Extract key data points:
– Contact ID
– Contact Name
– Previous Stage
– New Stage
– Timestamp
– Owner or other metadata
Example JavaScript snippet for verification:
“`javascript
const event = items[0].json;
// Perform validation
if (!event.newStage || !event.oldStage) {
return [];
}
return items;
“`
### Step 4: Format the Slack Message
1. Add a **Set** node to craft the message payload.
2. Use Markdown formatting and include relevant details:
“`markdown
*Contact Stage Update*
– Name: {{ $json[“contactName”] }}
– Previous Stage: {{ $json[“oldStage”] }}
– New Stage: {{ $json[“newStage”] }}
– Updated at: {{ $json[“timestamp”] }}
“`
3. Add links to CRM profiles if available.
### Step 5: Send Notification to Slack
1. Add a **Slack** node configured for “Post Message.”
2. Authenticate using Slack OAuth or Webhook URL.
3. Set the channel to your marketing team’s Slack channel.
4. Map the message content to the formatted text from the previous step.
### Step 6 (Optional): Log Event to Google Sheets
1. Create a Google Sheet with headers: Contact ID, Name, Old Stage, New Stage, Timestamp.
2. Add a **Google Sheets** node connected to the API and configured to append a new row with event details.
### Step 7: Test the Workflow
1. Trigger a stage change event in your CRM.
2. Observe n8n executing each node.
3. Confirm Slack message appears and, if enabled, log entry in Google Sheets.
### Step 8: Enable Workflow
Once tested, activate the workflow to run automatically.

## Breakdown of Each Node
– **Webhook / Cron:** Entry point capturing or polling stage change events.
– **HTTP Request (if polling):** Fetches updated contacts data from CRM.
– **Function:** Validates and extracts necessary fields.
– **Set:** Builds user-friendly message content.
– **Slack:** Sends message to marketing channel.
– **Google Sheets (Optional):** Maintains a historical record for audit or analytics.
—
## Common Errors and Tips
– **Webhook not triggering:** Verify CRM webhook URL is correct and active.
– **Authentication failures:** Recheck API keys, OAuth scopes, and refresh tokens.
– **Message formatting issues:** Test Slack message payload in Slack API tester for correctness.
– **Missing data in payload:** Confirm CRM sends all required fields; adapt function node accordingly.
– **Rate limits:** Adhere to API limits by batching or throttling requests.
To make it more robust, add error handling nodes in n8n to catch failures and send alerts.

## How to Adapt and Scale
– Add conditional logic to filter for only certain stages relevant to marketing.
– Integrate other channels besides Slack (e.g., email, Microsoft Teams).
– Use n8n workflow parameters to adapt to multiple CRM accounts or teams.
– Include enrichment steps such as fetching additional contact data or scoring.
– Export logs and notifications to BI tools for marketing insights.
