How to Send Zoho CRM VIP Case Alerts to Slack with n8n

n8n Canvas > + Add Node > Trigger > Webhook

Create a Webhook node in n8n

Open your n8n instance and click the '+' button to create a new workflow. Add a Webhook node as the trigger — this is what Zoho CRM will call when a new case is created. Set the HTTP Method to POST. n8n will generate a unique webhook URL once you save; copy it now. Leave Authentication set to None for initial testing — you'll lock this down before going live.

1. 1Click '+ Add first step' on the empty canvas
2. 2Search for 'Webhook' in the node panel and select it
3. 3Set HTTP Method to 'POST'
4. 4Set Path to a memorable slug like 'zoho-vip-case'
5. 5Click 'Copy Webhook URL' and save it to a notepad

Zoho CRM > Setup > Automation > Workflow Rules > + Create Rule

Create a Workflow Rule in Zoho CRM

In Zoho CRM, navigate to Setup > Automation > Workflow Rules and create a new rule targeting the Cases module. Set the trigger to 'Record Action: Create' so it only fires on new cases. Give the rule a clear name like 'New Case — Webhook to n8n'. You'll add the webhook call in a later sub-step; set the condition first.

1. 1Go to Setup (gear icon, top right) > Automation > Workflow Rules
2. 2Click '+ Create Rule'
3. 3Set Module to 'Cases'
4. 4Set 'When' to 'A record is Created'
5. 5Name the rule 'New Case — VIP Alert to n8n' and click Next

Zoho CRM > Workflow Rule Wizard > Step 2: Condition

Set the VIP filter condition in Zoho

Add a condition so only VIP or high-value accounts trigger the webhook — otherwise every case floods your Slack channel. In the Condition step, click 'Add Condition'. Filter on the field that marks high-value accounts in your CRM. Common options: 'Account Name contains VIP', a custom picklist field like 'Account Tier equals Enterprise', or 'Contact Role equals Key Decision Maker'. Use the condition that matches how your team actually tags accounts.

1. 1Click 'Add Condition' in the Condition step
2. 2Set Field to your VIP marker field (e.g., 'Account Tier')
3. 3Set Operator to 'equals'
4. 4Set Value to 'Enterprise' or 'VIP' depending on your picklist values
5. 5Click 'Next' to proceed to Actions

Zoho CRM > Workflow Rule Wizard > Step 3: Actions > Add Action > Webhook

Add the webhook action in Zoho

In the Actions step of the Workflow Rule wizard, click 'Add Action' and choose 'Webhook'. Click 'Configure Webhook' and paste the n8n webhook URL you copied in Step 1. Set Method to POST and Content Type to application/json. In the body, select 'Custom Body' and enter a JSON payload that includes all the case fields you need. Zoho provides merge variables like ${Cases.Subject} to pull live field values into the payload.

1. 1Click 'Add Action' and select 'Webhook'
2. 2Click '+ New Webhook' or 'Configure Webhook'
3. 3Paste the n8n Test Webhook URL into the URL field
4. 4Set Method to POST, Content Type to application/json
5. 5In the body, click 'Custom Body' and paste your JSON template (see field_mapping section for required fields)
6. 6Click 'Save' on the webhook, then 'Save' on the workflow rule

n8n Canvas > Webhook Node > Listen for Test Event

Test the Zoho-to-n8n connection

Back in n8n, click your Webhook node and hit 'Listen for Test Event'. Then in Zoho CRM, manually create a test case on a VIP account to trigger the rule. Within 10–20 seconds, n8n should receive the payload. Check the Input panel on the right side of the Webhook node — you should see the full JSON object from Zoho. Verify all the fields you need (case ID, subject, account name, priority, owner) are present in the payload.

1. 1Click the Webhook node in n8n to open its panel
2. 2Click 'Listen for Test Event' (blue button)
3. 3Switch to Zoho CRM and create a new Case on a VIP account
4. 4Return to n8n and confirm the payload appeared in the Input panel
5. 5Expand the JSON tree to verify all expected fields are present

Add a Code node to filter and format the alert

Add a Code node after the Webhook node. This is where you validate the VIP condition (if you skipped Zoho-side filtering in Step 3) and build the Slack message payload. Use n8n's $input.first().json to access the incoming Zoho data. Write logic to check your VIP field, set a priority color for the Slack attachment, and construct the message text. See the pro_tip_code section for a complete ready-to-paste example.

1. 1Click '+' after the Webhook node to add a new node
2. 2Search for 'Code' and select it
3. 3Set Language to 'JavaScript'
4. 4Paste your transformation logic into the editor (see pro_tip_code below)
5. 5Click 'Test Step' to verify the output object looks correct

Paste this into the Code node added in Step 6. It reads the Zoho webhook payload, validates the VIP account tier, picks a Slack color based on case priority, truncates the description to 200 characters, formats the created timestamp in human-readable EST, and returns a clean object that the Slack node can consume directly without any extra nodes.

// n8n Code Node — Zoho CRM VIP Case Alert Formatter
// Paste into: Code node between Webhook trigger and Slack node
const item = $input.first().json;

// n8n Code Node — Zoho CRM VIP Case Alert Formatter
// Paste into: Code node between Webhook trigger and Slack node

const item = $input.first().json;

// --- VIP Validation ---
// Remove this block if filtering is already handled in Zoho Workflow Rule conditions
const vipTiers = ['VIP', 'Enterprise', 'Strategic'];
const accountTier = item.Account_Tier__c || '';
if (!vipTiers.includes(accountTier)) {
  // Return empty array — n8n will skip downstream nodes silently
  return [];
}

// --- Priority Color Mapping ---
const colorMap = {
  Critical: '#FF0000',  // Red
  High:     '#FF8C00',  // Orange
  Normal:   '#FFC300',  // Yellow
  Low:      '#36A64F',  // Green
};
const color = colorMap[item.Priority] || '#AAAAAA';

// --- Priority Emoji ---
const emojiMap = {
  Critical: '🚨',
  High:     '⚠️',
  Normal:   'ℹ️',
  Low:      '🔵',
};
const emoji = emojiMap[item.Priority] || '📋';

// --- Description Truncation ---
const rawDescription = item.Description || 'No description provided.';
const shortDescription = rawDescription.length > 200
  ? rawDescription.substring(0, 197) + '...'
  : rawDescription;

// --- Timestamp Formatting ---
// Zoho sends ISO 8601 — convert to readable local string
const createdDate = new Date(item.Created_Time);
const formattedDate = createdDate.toLocaleString('en-US', {
  timeZone: 'America/New_York',
  month: 'short',
  day: 'numeric',
  hour: 'numeric',
  minute: '2-digit',
  timeZoneName: 'short',
});

// --- Case URL ---
// Replace YOUR_ORG_ID with your Zoho org ID (found in Zoho CRM URL)
const orgId = 'YOUR_ORG_ID';
const caseUrl = `https://crm.zoho.com/crm/${orgId}/Cases/${item.id}`;

// --- Slack Channel Routing ---
// Route Critical cases to a separate escalation channel
const slackChannel = item.Priority === 'Critical'
  ? '#support-critical'
  : '#support-vip';

// --- Output Object ---
return [{
  json: {
    slackChannel,
    messageText: `${emoji} *${accountTier} Case Alert* — ${item.Account_Name}`,
    color,
    caseSubject:   item.Subject,
    priority:      item.Priority,
    status:        item.Status,
    owner:         item.Owner || 'Unassigned',
    contactName:   item.Contact_Name || 'Unknown',
    description:   shortDescription,
    createdAt:     formattedDate,
    caseUrl,
    accountName:   item.Account_Name,
  }
}];

n8n Canvas > Slack Node > Credentials > Create New > Slack OAuth2

Connect your Slack account in n8n

Add a Slack node after the Code node. Click 'Create New Credential' and choose OAuth2. You'll be redirected to Slack's OAuth page — select the workspace and the channel(s) you want the bot to post in. n8n requires a Slack app with at minimum chat:write and chat:write.public scopes. If you don't have a Slack app yet, create one at api.slack.com/apps in under 5 minutes before this step.

1. 1Click '+' after the Code node and search for 'Slack'
2. 2Select the Slack node and set Resource to 'Message', Operation to 'Send'
3. 3Click 'Credential for Slack API' > 'Create New'
4. 4Select 'OAuth2' and click 'Connect my account'
5. 5Authorize the Slack app in the popup and confirm the green 'Connected' badge appears

n8n Canvas > Slack Node > Parameters

Configure the Slack message fields

In the Slack node, set Channel to the expression pulling from your Code node output — drag from the Input panel or type {{ $json.slackChannel }}. Set Text to {{ $json.messageText }}. Scroll down and enable 'Attachments' to add a colored sidebar (red for critical, orange for high). Map the color and fields from your Code node output. This gives the alert a scannable layout in Slack instead of a wall of text.

1. 1Set Channel to {{ $json.slackChannel }} using the expression editor
2. 2Set Text to {{ $json.messageText }}
3. 3Toggle 'Attachments' on
4. 4Set Attachment Color to {{ $json.color }}
5. 5Add attachment fields: 'Account' → {{ $json.accountName }}, 'Priority' → {{ $json.priority }}, 'Case URL' → {{ $json.caseUrl }}

n8n Canvas > Slack Node > ⋯ Menu > Add Error Handler

Add an error handler node

Click the three-dot menu on the Slack node and select 'Add Error Handler'. Add a second Slack node connected to the error output, pointing to a different channel like #alerts-errors. This way, if Zoho sends a malformed payload or Slack's API is down, the on-call engineer gets notified instead of the failure disappearing silently. Set the error message text to include {{ $json.message }} so you can see the actual error.

1. 1Right-click (or click ⋯) on the Slack node
2. 2Select 'Add Error Handler'
3. 3A red error connector appears — click '+' on it
4. 4Add another Slack node connected to this error output
5. 5Set its Channel to '#alerts-errors' and Text to 'VIP case alert failed: {{ $json.message }}'

n8n Canvas > Webhook Node > Production URL | Canvas Top-Right > Active Toggle

Activate the workflow and swap to Production URL

Before activating, go back to your Webhook node and copy the Production URL (not the Test URL — it starts with /webhook/ not /webhook-test/). Update your Zoho CRM webhook configuration to use this Production URL. Then toggle the workflow Active in n8n using the toggle in the top-right corner. Run one more real test in Zoho by creating a VIP case and confirm the Slack message arrives within 15 seconds.

1. 1Click the Webhook node and copy the 'Production URL'
2. 2Go to Zoho CRM > Setup > Automation > Workflow Rules > your rule > Edit Webhook action
3. 3Replace the Test URL with the Production URL
4. 4Save the webhook in Zoho
5. 5Back in n8n, click the Active toggle (top right) to turn it on — it should turn blue
