Location-aware context
Make branch, device, legal entity, and credential selection explicit.
Reliability guide
Retry the operation safely—or do not retry it at all.
Keep store, legal entity, EGS/device, credential, invoice type, request, and final outcome connected across online, retry, and recovery paths.
Built for
The team that must operate the integration.
POS vendors, retail technology teams, restaurant platforms, and multi-location operators.
Safe repeated attempts
Use durable idempotency rather than assuming one terminal or worker will submit once.
Supportable artifacts
Connect XML, QR, state, errors, and request IDs to the source transaction.
Implementation path
From source operation to an inspectable result.
Map the sale and invoice types
Separate simplified and standard paths and define correction behavior.
Create sandbox credentials
Provision the organization and test scoped requests.
Test interruption paths
Exercise timeout, offline replay, duplicate worker, and failed local commit scenarios.
Gate production separately
Complete customer-specific credentials and evidence before external traffic.
Questions
Decide with the boundary visible.
Availability and external prerequisites stay explicit throughout evaluation.
Does the API replace our POS?+
No. It supplies the invoice rail and operating controls for the POS you already run.
Can we test offline recovery?+
The synthetic sandbox can support contract and lifecycle evaluation; device-specific offline behavior must be tested in the POS integration.
