How to Send Lost Deal Alerts from Zoho CRM to Slack with Zapier

zapier.com > Dashboard > Create Zap

Create a new Zap in Zapier

Log into your Zapier account at zapier.com. Click the orange 'Create Zap' button in the top-left sidebar. You'll land on the Zap editor, which opens with an empty trigger block labeled 'Trigger' on the left side of the canvas. This is where you'll connect Zoho CRM as the event source.

1. 1Log in at zapier.com
2. 2Click the orange 'Create Zap' button in the left sidebar
3. 3The Zap editor opens — you'll see a blank canvas with a 'Trigger' block

Zap Editor > Trigger Block > Search Apps

Set Zoho CRM as the trigger app

Click the empty trigger block. A search panel slides in from the right. Type 'Zoho CRM' and select it from the results. Zapier will show a list of available trigger events for Zoho CRM. Choose 'Updated Deal' — this fires whenever any deal record is modified, which is how you'll catch the stage change to Lost.

1. 1Click the empty 'Trigger' block
2. 2Type 'Zoho CRM' in the search bar
3. 3Select 'Zoho CRM' from the results
4. 4Under 'Trigger Event', select 'Updated Deal'
5. 5Click 'Continue'

Zap Editor > Trigger > Choose Account > Sign in to Zoho CRM

Connect your Zoho CRM account

Click 'Sign in to Zoho CRM'. A popup window opens asking you to authorize Zapier. Log in with your Zoho credentials and click 'Accept' to grant access. Zapier needs read access to your Deals module to pull deal data. Once authorized, the popup closes and your Zoho account email appears in the dropdown.

1. 1Click 'Sign in to Zoho CRM' button
2. 2In the popup, log in with your Zoho credentials
3. 3Click 'Accept' on the OAuth permissions screen
4. 4Back in Zapier, confirm your Zoho email is selected in the account dropdown
5. 5Click 'Continue'

Zap Editor > Trigger > Test Trigger

Test the trigger to pull sample deal data

Click 'Test trigger'. Zapier polls Zoho CRM for the 3 most recently updated deals in your account. These are displayed as labeled data records you can expand. You need sample data here so Zapier can show you available fields in the next steps — specifically Deal Stage, Loss Reason, and Competitor fields. If no deals appear, update any deal in Zoho CRM manually to generate a test record.

1. 1Click 'Test trigger'
2. 2Wait 5-10 seconds for Zapier to poll Zoho CRM
3. 3Expand the returned records to confirm you can see fields like 'Stage', 'Reason for Loss', and 'Competitor'
4. 4Click 'Continue with selected record'

Zap Editor > + Button > Built-in Apps > Filter

Add a Filter step to catch only Lost deals

Click the '+' button between the trigger and the next action block. Select 'Filter' from the built-in Zapier tools (it's listed under 'Built-in Apps'). This filter checks whether the deal's Stage field equals 'Lost' before passing it on to Slack. Without this step, every single deal update in Zoho CRM — stage changes, note additions, field edits — will trigger a Slack notification.

1. 1Click the '+' icon between the trigger and action blocks
2. 2Click 'Filter' under Built-in Apps
3. 3In 'Only continue if...', click the field selector and choose '1. Deal Stage' from Zoho CRM
4. 4Set the condition to '(Text) Exactly matches'
5. 5Type 'Lost' in the value field (case-sensitive — match exactly how Zoho stores it)
6. 6Click 'Continue'

Zap Editor > + Action > Formatter by Zapier > Text > Merge

Add a Formatter step to build the Slack message text

Click '+' to add an action. Search for 'Formatter by Zapier' and select it. Choose the 'Text' action type, then 'Merge' as the transform. This lets you combine multiple Zoho CRM fields — deal name, amount, loss reason, competitor — into a single formatted string you can drop into Slack. This is cleaner than constructing the message inline inside the Slack step, especially when some fields like Competitor may be blank.

1. 1Click '+' to add an action step
2. 2Search for 'Formatter by Zapier' and select it
3. 3Choose action event 'Text', then select 'Merge'
4. 4In the 'Input' field, map these Zoho CRM fields in sequence: Deal Name, Amount, Stage, Reason for Loss, Competitor
5. 5Set the 'Separator' to a newline character by clicking the field and pressing Shift+Enter
6. 6Click 'Continue', then 'Test action'

Zap Editor > + Action > Slack > Send Channel Message

Add Slack as the action app

Click '+' to add the next action. Search for 'Slack' and select it. Choose 'Send Channel Message' as the action event — this posts a message to a public or private Slack channel. You'll connect your Slack workspace in the next sub-step. The bot will post as a Zapier-owned Slack app by default, but you can customize the bot name and icon in the action configuration.

1. 1Click '+' to add an action
2. 2Search for 'Slack' and select it
3. 3Choose 'Send Channel Message' as the action event
4. 4Click 'Sign in to Slack'
5. 5Authorize Zapier in the Slack OAuth popup — select the correct workspace
6. 6Click 'Continue'

Zap Editor > Slack Action > Configure

Configure the Slack message content

In the 'Channel' field, type or select your target channel name — for example, #lost-deals or #sales-leadership. In the 'Message Text' field, click into it and map the merged output from the Formatter step. Add static labels so the message is readable at a glance: include 'Deal:', 'Amount:', 'Lost Reason:', and 'Competitor:' as prefixes. Set 'Bot Name' to something like 'Deal Tracker' and optionally add an emoji icon like :chart_with_downwards_trend:.

1. 1In 'Channel', select or type your management Slack channel (e.g. #lost-deals)
2. 2In 'Message Text', click the field and insert the merged Formatter output
3. 3Prepend each line with a label: '*Deal:* ', '*Amount:* ', '*Lost Reason:* ', '*Competitor:* '
4. 4Set 'Bot Name' to 'Deal Tracker'
5. 5Optionally set 'Bot Icon' to ':chart_with_downwards_trend:'
6. 6Click 'Continue'

Zap Editor > Slack Action > Test Action

Test the full Zap end-to-end

Click 'Test action' in the Slack step. Zapier sends a real test message to the channel using your sample deal data. Open Slack and navigate to the target channel to verify the message arrived correctly. Check that the deal name, amount, loss reason, and competitor fields all display as expected. If any field shows as blank or displays an internal Zoho ID instead of a label, go back to the Formatter step and adjust the field mapping.

1. 1Click 'Test action' in the Slack step
2. 2Open Slack and navigate to your target channel
3. 3Confirm the test message appears with correct field data
4. 4Check that 'Lost Reason' and 'Competitor' are populated (if your sample deal had those values)
5. 5If the message looks correct, click 'Publish Zap'

Zap Editor > Toggle (top right) > On

Turn on the Zap and verify the first live trigger

Click the toggle in the top-right corner of the Zap editor to turn it on. The Zap is now active and polling Zoho CRM every 5-15 minutes (depending on your Zapier plan). To verify it works in production, go to Zoho CRM and mark a real deal as Lost with a reason code. Wait up to 15 minutes and check Slack. You can also check Zap History at zapier.com/app/history to confirm the Zap ran and see exactly what data it processed.

1. 1Click the 'Turn on Zap' toggle in the top right of the editor
2. 2Confirm the Zap status shows 'On'
3. 3In Zoho CRM, mark a test deal as Lost and add a reason code
4. 4Wait up to 15 minutes for Zapier's polling cycle
5. 5Check Slack for the notification and check zapier.com/app/history for the run log

This Code by Zapier step solves the blank competitor problem: if the Competitor field is empty, it substitutes '—' so the Slack message always has a clean, consistent layout. It also formats the Amount as currency and checks for missing Loss Reason. Paste this into a 'Code by Zapier' (JavaScript) step inserted between the Filter and the Slack action, then map its output fields into the Slack message instead of the raw Zoho CRM fields.
