Workflow Change Audit Log

Workflow Change Audit Log

This template turns Heym's own platform events into an audit trail. A Heym Trigger subscribes to workflow lifecycle events, a Heym node pulls the current structure of the changed workflow, and a Slack message reports the whole batch.

What this workflow does

1. PlatformEvents wakes up when a workflow is created, updated, or deleted
2. ChangedWorkflow reads the affected workflow's current node list
3. AuditMessage posts a single Slack summary covering every event in the batch

Use cases

• Audit trails for teams sharing one Heym instance
• Noticing an unexpected workflow deletion the moment it happens
• A running record of what changed, when, and who changed it

Setup

Add a Slack credential to AuditMessage. The Heym nodes need no credential at all: they read only what the workflow owner can already reach, which means their own workflows plus anything shared with them.

Notes

Delivery is batched. Everything published inside the same five second dispatch window arrives in one run as $PlatformEvents.events, always an array. Add a Loop node over that array when you want one message per event instead of one per batch. Each event is claimed through a unique database constraint, so running Heym on two containers still fires the workflow exactly once.
