What changed in the workflow platform

Testing

Simulate and inspect a workflow run

The simulator can walk a workflow branch before a WhatsApp number is connected, while the debug panel exposes variables, execution position, stack, and canvas highlighting.

Deployment

Publish immutable workflow versions

Publishing validates the flow and creates a versioned immutable snapshot, so a live workflow does not change with an in-progress draft.

Current limitation: Self-service publication history and rollback controls are not available; restoring a previous snapshot is a support request.

Knowledge

Ground answers in uploaded knowledge

Knowledge nodes can answer from a bot's uploaded source material and route an unanswered question to an intentional fallback.

Operations

Escalate conversations to an operator

A Handoff node opens a support ticket, pauses the workflow, and can return control after an operator resolves the ticket.

Campaigns

Run consent-aware template campaigns

Campaigns let operators preview an audience and send or schedule approved WhatsApp templates to consented contacts.

Integrations

Extend a flow with HTTP and code

HTTP request nodes map responses into flow variables, and code nodes run JavaScript or Python with explicit inputs and outputs.
