monday.com Automation Safety: Preventing Duplicate Items

meta_description: “monday.com automations have no deduplication or idempotency guards. Toggling status twice fires the automation twice. Learn why and how BoardBridge prevents duplicates with idempotency logic.”

Status changes to “Confirmed.” Automation fires. Travel item created.

User accidentally toggles the status back to “Pending” and then to “Confirmed” again.

Automation fires again. Second travel item created.

Now you have two travel items for the same person.

Do it five times (testing, accidental clicks, status corrections), and you have five duplicate items cluttering your board.

Monday.com automations have no memory. No deduplication. No “already ran” check.

Every trigger fires every time, even if it already ran.

Automation Pain Point #23-27: No Safety Guards or Idempotency in Monday.com

Here’s what teams need:

Idempotency — automations that don’t re-run if they already executed:

• Status toggled back and forth → automation fires once, not five times
• Button clicked twice → action runs once
• “Already exists” check → don’t create duplicate items

Pre-action validation — block automations when required data is missing:

• Don’t send email if recipient column is empty
• Don’t create item if required fields are blank
• Don’t fire button action if form isn’t filled out yet

Deduplication — prevent duplicate items by name, email, or other unique identifier:

• Don’t create two travel items for the same person
• Don’t create duplicate vendor entries
• Check if item already exists before creating

Safety prompts — confirm before destructive actions:

• “Are you sure you want to send this email to 50 clients?”
• “This will create items on 5 boards. Continue?”

Rollback/undo — reverse automation actions if triggered by mistake:

• Undo item creation
• Recall sent email
• Restore previous status

What monday.com offers:

None of the above.

• Automations fire every time, even if they already ran
• No validation before actions execute
• No duplicate checking
• No confirmation prompts
• No rollback (once fired, actions are permanent)

Related feature in monday.com CRM: monday.com CRM users have a “Manage Duplicates” tool, but this is manual merge only — it does NOT prevent duplicate item creation via automation. Deduplication must be done by hand, after duplicates are already created.

The result: Duplicate items, duplicate emails, test data mixed with production, and no way to undo mistakes.

What Monday.com Users Are Saying

Thread: Item duplication to infinity — November 2023

“when a form submission comes in, given certain responses, the item will be duplicated and the copy will be moved to another group” — rosenthd (David Rosenthal), November 9, 2023

“‘When an item is created, duplicate it’ is indeed causing a loop” — basdebruin (Bas de Bruin), November 9, 2023

No monday.com staff response. Community workaround uses a status field to break the duplication cycle.

Thread: Why does an automation keeping repeating — August 2021

“continuous loop of the item appearing as a new pulse in the other board every 15 seconds” — MDPAdmin (Ramon Utting), August 17, 2021

“I deleted the automations and wrote them again with success” — MDPAdmin, August 17, 2021

The only fix was deletion and recreation. No monday.com staff response.

Thread: Trigger status change automation only when changed by user — August 2023 – July 2024 (11 months unresolved)

“Is it possible to trigger a status change automation only when the change is made by a user and not when the status was changed by an automation?” — dk_NFroehlich, August 10, 2023

“still looking for a way to take into account who triggers an automation.” — dk_NFroehlich, July 29, 2024

“there is no way to differentiate whether a change is made by a person or via an automation. Perhaps it is possible to do so via the API, but this would require implementation and maintenance costs.” — GiannisKoukounas (Implementation Consultant), August 30, 2023

No monday.com staff response. Confirmed unsupported by community experts.

Thread: Possible infinite loop caused by API and Monday integrations — January 2023

No monday.com staff response. Only third-party paid apps ($49/mo+) address this.

Official documentation (Required columns): Required column validation exists for manual moves but NOT as a pre-condition for automation-triggered actions.

How BoardBridge Solves This

Source: BoardBridge Product Documentation https://www.taskrhino.ca/products/boardbridge

1. Idempotency: 5-Second Deduplication Window

Problem: User toggles status back and forth. Same automation fires multiple times.

BoardBridge solution:

When an automation fires, the system checks: “Did this exact automation already run on this item in the last 5 seconds?”

If yes → skip the action (deduplicate).

Example:

• 2:00:00 PM — Status changes to “Confirmed” → automation fires → travel item created
• 2:00:02 PM — Status changes to “Pending”
• 2:00:03 PM — Status changes to “Confirmed” again → automation checks: “Did I already run at 2:00:00?” → Yes (within 5 seconds) → skip

Result: Only one travel item created, even though the trigger fired twice.

Why 5 seconds? Long enough to catch accidental double-clicks and status toggles, short enough to allow legitimate re-runs (e.g., user intentionally re-confirms after 10 seconds).

2. Name-Based Idempotency

Problem: Same person confirmed twice (status toggled). Don’t create two travel items with the same name.

BoardBridge solution:

Before creating an item on the Travel board, check: “Does an item with this exact name already exist on this board?”

If yes → skip item creation.

Example:

• First confirmation: “Alex Johnson” → Travel item created: “Alex Johnson – Outbound Travel”
• Status toggled back and forth
• Second confirmation: “Alex Johnson” → System checks: “Alex Johnson – Outbound Travel” already exists → skip

Result: Only one travel item per person, regardless of how many times the status is toggled.

Limitation: Name-based deduplication only works if item names are unique. If you have two different “Alex Johnson” entries, the system cannot distinguish them.

3. Event Folder Existence Check

Problem: CRM deal moves to “Won” twice (toggled back to “In Progress,” then back to “Won”). Don’t create two project folders.

BoardBridge solution:

Before creating a project folder, check: “Does a folder with this name already exist?”

If yes → skip the entire project creation workflow.

Example:

• First “Won” trigger: Folder “Acme Corp Event” created, boards duplicated
• Deal moved back to “In Progress” (to fix something)
• Deal moved to “Won” again → System checks: Folder “Acme Corp Event” exists → skip

Result: Only one project folder created per deal, even if status is toggled.

4. Pre-Action Validation: Required Fields

Problem: Button triggers email, but recipient column is empty.

BoardBridge solution:

Add conditions to the automation:

• Condition 1: Email is_not_empty
• Condition 2: Event Date is_not_empty
• If conditions not met → block action, log error

Example:

• Button “Send Forms” clicked
• System checks: Email column → empty
• Action blocked
• Error logged: “Cannot send email: recipient column is empty”

Result: Email does not send to an empty address. User is notified via error log.

5. Retry Logic (Not Idempotency, but Safety)

Problem: API call fails (monday.com API timeout). Does the automation retry or silently fail?

BoardBridge solution:

All API calls retry with exponential backoff:

• First attempt fails → wait 1 second → retry
• Second attempt fails → wait 2 seconds → retry
• Third attempt fails → wait 4 seconds → retry
• After 3 retries → log error, stop

Result: Transient failures (network glitches, API slowdowns) are handled automatically. Permanent failures (bad data, invalid board ID) are logged for debugging.

Real-World Example: Vendor Confirmation Deduplication

Vendor Confirmations Board:

• Vendor: “Alex Johnson”
• Status: “Pending”

User accidentally clicks status twice:

• 2:00:00 PM — Status changes to “Confirmed”
• Automation fires
• Checks: “Travel item for Alex Johnson exists?” → No
• Creates: “Alex Johnson – Outbound Travel”
• 2:00:02 PM — Status accidentally changed to “Pending” (mis-click)
• 2:00:03 PM — Status changed back to “Confirmed”
• Automation fires again
• Checks: “Did this automation already run in the last 5 seconds?” → Yes (at 2:00:00)
• Skips (5-second deduplication window)

Result: Only one travel item created.

Alternative scenario (without 5-second window but with name-based check):

• 2:00:00 PM — “Confirmed” → Travel item created: “Alex Johnson – Outbound Travel”
• 2:10:00 PM — Status toggled to “Pending” then back to “Confirmed” (10 minutes later)
• 5-second window expired
• Automation fires
• Checks: “Travel item named ‘Alex Johnson – Outbound Travel’ exists?” → Yes
• Skips (name-based deduplication)

Result: Still only one travel item, even 10 minutes later.

Three Layers of Idempotency

BoardBridge uses three layers of duplicate prevention:

Layer	Check	Time Window	Use Case
1. Time-based	Did this automation already run on this item recently?	5 seconds	Accidental double-clicks, rapid status toggles
2. Name-based	Does an item with this name already exist on the target board?	Unlimited	Same person confirmed multiple times
3. Folder-based	Does a folder with this name already exist?	Unlimited	CRM deal status toggled back and forth

Each layer catches different duplication scenarios.

Limitations You Should Know

Name-based deduplication requires unique names. If two different people have the same name (“John Smith”), the system cannot distinguish them. Best practice: use unique identifiers in item names (e.g., “John Smith – Event 123”).

5-second window is fixed. You cannot configure a longer or shorter deduplication window. 5 seconds is the balance between catching accidental triggers and allowing intentional re-runs.

Deduplication is per-board, not workspace-wide. If you have two Travel boards and both have an item named “Alex Johnson,” the deduplication check only looks at the specific target board configured in the automation.

No rollback for actions already executed. If an item is created before deduplication logic runs (e.g., in an older version of the workflow), you’d manually delete it. Deduplication prevents future duplicates but doesn’t clean up past ones.

Protect Your Workflows from Duplicates

Without idempotency, automations are a liability. Teams either:

• Accept duplicate items and manually clean them up (labor-intensive, error-prone)
• Disable automations that risk duplicates (less useful, less automation)
• Over-engineer workarounds with helper columns and conditional logic (complex, fragile)

BoardBridge includes built-in idempotency — time-based deduplication for fast re-triggers, name-based checking for item creation, full audit logging. Same automation, five times triggered, one result.
