Integration Approach
Connect kiosks as a first‑class citizen in your retail stack.
SentinelKiosk supports multiple integration models to suit infrastructure, preferences, and compliance.
API‑Based Integration
RESTful APIs with HTTPS/TLS; auth via OAuth 2.0, API keys, or JWT.
GraphQL supported for precise queries (product, pricing, cart totals).
Middleware Connectors
- Data transformation & mapping
- Queuing/caching for offline & spikes
- Unified API across multiple backends
Direct Database Integration
- ODBC/JDBC to SQL backends
- Replicated DBs to protect live systems
- Role‑based accounts & stored procedures
File‑Based & Batch
CSV/XML/JSON via (S)FTP with scheduled imports/exports where real‑time isn’t available.
Security & Authentication
- All comms over HTTPS/TLS with modern ciphers
- Auth: API keys, OAuth2, SAML, PKI certificates
- Encryption at rest (e.g., AES‑256 on device)
- Auditing with transaction IDs & timestamps
Offline & Resilience
- Local cache for products, prices, promos
- Transaction queuing & replay after outage
- Endpoint monitoring, retries, and alerts
Example Integration Flows
Proven patterns for retail use‑cases
1) In‑Store Checkout (EPOS REST API)
- Scan items → GET /api/products/{sku}
- Build cart, optional loyalty lookup
- POST /api/cart/price for totals/taxes
- Take payment (card/NFC or cash if enabled)
- POST /api/sales commit → saleId; print/email receipt
Resilience: If commit unavailable, queue as PendingCommit; print receipt marked “pending”.
2) Click‑and‑Collect Pickup (GraphQL + EPOS)
- Scan pickup QR → query orderByCode
- Verify customer (face/ID/OTP as required)
- Print pick ticket or open locker via API
- Update statuses (ReadyForPickup → PickedUp)
- Optional loyalty earn + digital receipt
Resilience: If endpoint down, use cached headers and emit PickupDeferred for backfill.
3) Returns & Refunds (Middleware + EPOS)
- Validate proof‑of‑purchase via middleware
- Apply policy & fraud checks → RMA decision
- POST /api/returns with items & refund route
- Payout via PSP, cash device, or store credit
- Print return receipt; publish events
Resilience: If print fails post‑refund, allow admin reprint via persisted returnId.
4) Price Check & Inventory (GraphQL + Cache)
- Query local cache; fall through to productBySku
- Check store/nearby stock via inventory APIs
- Present offers; optional loyalty login
- Next steps: add to cart, reserve, or directions
Resilience: If online checks fail, show cached price; prompt staff and raise alert.
5) Cash‑Accepting Checkout (Validators + EPOS)
- Totals from Flow #1
- Enable coin (G13/RM5/D4S) & bill (ITL NV9/CPI SC Advance) validators
- Compute change; command hoppers/dispensers
- POST /api/sales with cash tender breakdown
- Print receipt; log cashbox counters + webhook
Resilience: If commit fails after cash accept, lock session and retry; allow admin reconciliation.
Administration & Operations
- Provisioning & deployment across locations
- Monitoring & centralized log aggregation
- Secure remote access for updates & diagnostics
- Scales from a handful of kiosks to hundreds
