How it runs

The automated pipeline, trigger to output.

  • TriggerMonday card-moved webhookmonday.com
  • ActionCount destination column, read cap from PostgresPostgreSQLPostgres
  • LogicExit if column still under its WIP cap
  • ActionLabel the overflowing card on Mondaymonday.com
  • OutputNotify the mover on Slack with count vs capSlack

What it does

Enforces WIP limits at the exact moment of violation. Instead of a periodic sweep, this catches the card that pushed a column over its cap, marks it, and tells the mover immediately so the queue never silently overflows.

When to use it

Use it on fast-moving boards where periodic checks are too slow and people add work mid-sprint. Ideal when the cultural rule is "finish before you start" and you want instant, friendly feedback rather than a daily report.

How it works

  1. 1A Monday webhook trigger fires when an item changes column.
  2. 2The flow re-counts the destination column and reads its limit from Postgres.
  3. 3A logic branch exits quietly if the column is still within its cap.
  4. 4On overflow, the flow adds a 'WIP exceeded' label to the offending item in Monday.
  5. 5It identifies the user who made the move and sends a Slack message naming the column, the count, the cap, and a suggestion to pull something to Done first.
  6. 6The event is recorded in Postgres for trend reporting.
