TNB cf1e09e1c4 Rename product TallyFlow IoT → TallyFlow Edge across vault

Update product naming in docs, marketing, architecture, use cases,
and capabilities materials. Rename related notes, screenshot folder,
and marketing image filenames. Keep git/repo identifiers (e.g.
tallyflow-iot) and generic industry IoT language unchanged.

ServiceNow Integration Approach

Status: Recommended Pattern
Date: 2026-07-07

Overview

TallyFlow should integrate with ServiceNow through TallyFlow Core rather than directly from TallyFlow Assets (Mobile) or other components. Core acts as the integration hub and single source of truth for field operations data.

Recommended Architecture

    A[TallyFlow Assets Mobile] -->|REST / WebSocket| B[TallyFlow Core]
    C[TallyFlow Print] -->|REST| B
    D[TallyFlow Capture] -->|REST| B
    E[TallyFlow Edge] -->|REST / MQTT| B
    B -->|REST / Integration Hub| F[ServiceNow]
    F -->|REST| B

Core Principle: All external systems, including ServiceNow, connect to TallyFlow Core.

Data Flow Directions

Direction	Typical Data	Trigger	Recommended Method
ServiceNow → TallyFlow	Asset master data, locations, status	Scheduled or event-driven	ServiceNow Integration Hub → Core REST
TallyFlow → ServiceNow	Real-time location, RFID scans, condition updates	Mobile scan, Edge event, zone change	Core → ServiceNow REST / Flow Designer
Bidirectional	Asset status synchronization	On change or scheduled	Core as middleware

Key Integration Points

1. Asset Master Data

ServiceNow remains the system of record for asset metadata.
TallyFlow Core receives updates (new assets, location changes, status).
TallyFlow enriches ServiceNow records with RFID tag data, real-time location, and movement history.

2. Field Operations Data

TallyFlow Assets (Mobile) captures RFID scans, photos, zone movements, and condition data.
This data is pushed to ServiceNow for visibility in Asset Management, Work Orders, or CMDB.

3. Real-time Location & Condition

Edge and mobile events flow through Core and are published to ServiceNow (via REST or Integration Hub).

Authentication & Security

Use OAuth 2.0 or ServiceNow Integration Hub credentials from Core.
Core should manage token refresh and retry logic.
Avoid embedding ServiceNow credentials in the mobile app.

Benefits of Routing Through Core

Maintains TallyFlow’s offline-first capabilities.
Ensures consistent data model and audit trail.
Simplifies future integrations (ERP, WMS, etc.).
Allows TallyFlow to act as a specialized asset tracking layer on top of ServiceNow.

Next Steps (Typical Engagement)

Define asset data model mapping between ServiceNow and TallyFlow.
Identify events that should trigger synchronization.
Build or configure a lightweight connector in TallyFlow Core.
Use ServiceNow Integration Hub or REST Message for the ServiceNow side.
Test bidirectional sync and conflict resolution rules.
