How to Send Zoho CRM Deal Stage Updates to Slack with n8n

n8n Canvas > + New Workflow

Create a new workflow in n8n

Open your n8n instance and click the '+ New Workflow' button in the top-right corner of the canvas screen. Give the workflow a clear name like 'Zoho CRM Deal Stage → Slack'. You'll land on a blank canvas with a single node prompt in the center. This is where you'll add the webhook trigger node first.

1. 1Click '+ New Workflow' in the top-right corner
2. 2Click the workflow title at the top and rename it to 'Zoho CRM Deal Stage → Slack'
3. 3Click the '+ Add first step' button in the center of the canvas

Canvas > Add Node > Webhook

Add a Webhook trigger node

In the node search panel, type 'Webhook' and select the core Webhook node. Set the HTTP Method to POST and leave the path as the auto-generated UUID — you'll copy this URL into Zoho CRM in the next step. Switch the node to 'Test' mode first so you can capture a live payload from Zoho before building the rest of the workflow. The webhook URL will look like https://your-n8n-instance.com/webhook-test/[uuid].

1. 1Type 'Webhook' in the node search box and select the Webhook node
2. 2Set HTTP Method to 'POST'
3. 3Copy the Test URL shown at the top of the node panel
4. 4Leave Authentication set to 'None' for now

Zoho CRM > Setup > Automation > Actions > Webhooks

Configure Zoho CRM webhook to fire on stage changes

In Zoho CRM, navigate to Setup > Automation > Actions > Webhooks and click '+ New Webhook'. Name it 'n8n Deal Stage Trigger', paste the n8n Test URL into the URL field, and set the method to POST. Under 'Module', select 'Deals'. You'll set the actual trigger condition (stage field change) in the Workflow Rules step, not here — this step just registers the endpoint.

1. 1Go to Setup > Automation > Actions > Webhooks
2. 2Click '+ New Webhook'
3. 3Set Method to POST and paste the n8n Test URL
4. 4Under 'Module', select 'Deals'
5. 5Under 'Parameters', add the merge fields: Deal Name, Stage, Amount, Owner, Account Name, Deal ID, Modified Time
6. 6Click Save

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

Create a Workflow Rule in Zoho CRM to fire on stage changes

Still in Zoho CRM, go to Setup > Automation > Workflow Rules and click '+ Create Rule'. Set the module to 'Deals' and the trigger to 'Field Update'. Set the condition to fire when the 'Stage' field is modified. Under Actions, attach the webhook you created in the previous step. This is what actually calls n8n when a deal moves stages — without this rule, the webhook never fires.

1. 1Click '+ Create Rule' and set Module to 'Deals'
2. 2Set Rule Trigger to 'Field Update'
3. 3Under 'Field', select 'Stage' and check 'Any Change'
4. 4Under Actions > Webhooks, attach the webhook you created in Step 3
5. 5Click Save and Activate

n8n Canvas > Webhook Node > Listen for test event

Capture a test payload from Zoho CRM

Back in n8n, click your Webhook node and hit 'Listen for test event'. Then go to Zoho CRM and manually edit a test deal — change its Stage field to something different and save. Within a few seconds, n8n should receive the payload and show the incoming fields on the right side of the node. This live payload is what all downstream nodes will reference for field names.

1. 1Click the Webhook node on the canvas
2. 2Click 'Listen for test event' in the node panel
3. 3Switch to Zoho CRM, open a test deal, and change the Stage field
4. 4Click Save on the deal in Zoho CRM
5. 5Return to n8n and confirm the payload appeared

Canvas > + > IF Node

Add an IF node to filter stage changes worth alerting

Click the '+' connector below the Webhook node and add an IF node. Set the condition to check whether the 'Stage' field from the webhook payload is not empty. This prevents the workflow from sending a Slack message if Zoho fires the webhook without a stage value — which can happen when other deal fields are updated simultaneously through Zoho automations. Route the True branch to the next step and leave the False branch empty.

1. 1Click the '+' below the Webhook node and search for 'IF'
2. 2Set Condition 1: Value 1 = {{ $json.Stage }}, Operation = 'is not empty'
3. 3Click 'Add condition' and set Value 1 = {{ $json.Stage }}, Operation = 'is not equal to', Value 2 = ''
4. 4Connect the True output to the next node

Canvas > + > Code Node > JavaScript

Add a Code node to build the Slack message

Click '+' on the True branch of the IF node and add a Code node. Set the language to JavaScript. Write logic here to format the Slack message text, including the deal name, stage, owner, and amount. You can also set an emoji based on the stage — Closed Won gets a trophy, Needs Analysis gets a magnifying glass, and so on. This keeps the Slack message readable without any additional Slack Block Kit setup.

1. 1Click '+' on the True output of the IF node
2. 2Search for 'Code' and select the Code node
3. 3Set Language to 'JavaScript'
4. 4Paste your formatting logic into the code editor (see Pro Tip below)
5. 5Click 'Test step' to preview the output

Paste this into the Code node in Step 7. It formats the Amount with commas and a dollar sign, picks an emoji based on the deal stage, and builds a Zoho CRM deep link so team members can click straight into the deal from Slack.

// n8n Code Node — Deal Stage Slack Message Formatter
// Paste this into the Code node between the IF node and the Slack node
const items = $input.all();

// n8n Code Node — Deal Stage Slack Message Formatter
// Paste this into the Code node between the IF node and the Slack node

const items = $input.all();

const stageEmojis = {
  'Qualification': ':mag:',
  'Needs Analysis': ':clipboard:',
  'Value Proposition': ':bulb:',
  'Identify Decision Makers': ':busts_in_silhouette:',
  'Perception Analysis': ':bar_chart:',
  'Proposal/Price Quote': ':memo:',
  'Negotiation/Review': ':handshake:',
  'Closed Won': ':trophy:',
  'Closed Lost': ':x:'
};

return items.map(item => {
  const data = item.json;

  const stage = data.Stage || 'Unknown Stage';
  const dealName = data.Deal_Name || 'Unnamed Deal';
  const owner = data.Owner || 'Unassigned';
  const accountName = data.Account_Name || '';
  const dealId = data.id || '';

  // Format amount as currency string
  const rawAmount = parseFloat(data.Amount) || 0;
  const formattedAmount = rawAmount.toLocaleString('en-US', {
    style: 'currency',
    currency: 'USD',
    minimumFractionDigits: 0,
    maximumFractionDigits: 0
  });

  // Pick emoji or default
  const emoji = stageEmojis[stage] || ':arrow_right:';

  // Build Zoho CRM deep link
  const crmBaseUrl = 'https://crm.zoho.com/crm/org/tab/Potentials';
  const dealLink = dealId ? `<${crmBaseUrl}/${dealId}|View Deal>` : '';

  // Build account context string
  const accountStr = accountName ? ` (${accountName})` : '';

  // Compose final message
  const message = `${emoji} *${dealName}*${accountStr} moved to *${stage}* — ${formattedAmount} | Owner: ${owner}${dealLink ? ' | ' + dealLink : ''}`;

  return {
    json: {
      message,
      stage,
      dealName,
      owner,
      formattedAmount
    }
  };
});

Canvas > + > Slack Node > Message > Send

Add the Slack node and configure the message

Click '+' after the Code node and search for 'Slack'. Select the Slack node and set the Resource to 'Message' and the Operation to 'Send'. Connect your Slack credential (OAuth2 — you'll need the chat:write scope). Set the Channel field to the target channel ID or name (e.g., #deals). In the Text field, reference the formatted message from the Code node: {{ $json.message }}.

1. 1Click '+' after the Code node and search for 'Slack'
2. 2Set Resource to 'Message', Operation to 'Send'
3. 3Click 'Credential for Slack' and connect your Slack OAuth2 app
4. 4Set Channel to '#deals' or paste the channel ID
5. 5Set Text to {{ $json.message }}
6. 6Optionally set Username to 'Deal Bot' and Icon to ':briefcase:'

Slack Node > Settings (gear icon) > Error Handling > Continue on Fail

Add error handling with a catch node

Click the three-dot menu on the Slack node and enable 'Continue on Fail'. Then add a second Slack node connected to the error output and configure it to message a private #alerts channel with the error details. This way, failed webhook deliveries don't silently disappear — your team sees the error in Slack rather than missing a deal update entirely.

1. 1Click the Slack node, then click the Settings tab inside the node panel
2. 2Toggle 'Continue on Fail' to ON
3. 3Click '+' on the error output branch
4. 4Add another Slack node pointing to a #workflow-alerts channel
5. 5Set Text to 'Deal stage webhook failed: {{ $json.error.message }} for deal {{ $node["Webhook"].json.Deal_Name }}'

n8n Canvas > Workflow toggle (top-right) > Active

Activate the workflow and swap to the Production URL

Before activating, go back to your Webhook node and copy the Production URL (not the Test URL). Then go to Zoho CRM > Setup > Automation > Actions > Webhooks, edit the webhook you created in Step 3, and replace the Test URL with the Production URL. Back in n8n, toggle the workflow to Active using the switch in the top-right of the canvas. The workflow now runs on every real deal stage change.

1. 1Click the Webhook node and copy the Production URL from the node panel
2. 2Go to Zoho CRM > Setup > Automation > Actions > Webhooks
3. 3Edit your webhook and replace the URL with the Production URL
4. 4Save the webhook in Zoho CRM
5. 5Return to n8n and toggle the workflow switch to Active

n8n Left Sidebar > Executions

Test with a live deal stage change

Go to Zoho CRM and move a real (or test) deal from one stage to another. Check your #deals Slack channel within 30 seconds. Then check the n8n Executions panel (left sidebar > Executions) to confirm the run shows as 'Success'. If it failed, click the execution to see exactly which node errored and what the payload looked like.

1. 1Open Zoho CRM and change a deal's Stage field
2. 2Check your #deals Slack channel for the notification
3. 3Click 'Executions' in the n8n left sidebar
4. 4Find the most recent execution and confirm it shows a green 'Success' badge
5. 5Click into the execution to inspect each node's input and output data
