From Scan to Metrc to Delivery: How a Cannabis Transport Compliance API Workflow Should Be Layered

The scanner, Metrc integration, transport engine, and payment rail are connected—but they should not be one giant function.

Quick answer

A reliable architecture separates capture, verification, regulated-system reconciliation, trip execution, receiving, and payment. Each layer owns one decision and passes a clear result to the next.

The proof questionIf the barcode SDK fails, can you repair scanning without risking Metrc, delivery completion, or payment logic?

Layer 1: capture the identifier

The scanner should read barcode, QR, or supported printed identifiers and normalize the result. It should not decide whether the package belongs on the load.

This layer can be upgraded independently as camera and SDK technology improves.

Layer 2: verify the load

The Flower Freight verification API checks the captured package against the expected load/Metrc context and updates the departure gate. This is where mismatch logic belongs.

Separating verification protects the workflow from a scanner that merely recognizes valid-looking text.

Layer 3: execute and reconcile transport

Driver custody, GPS, temperature observations, arrival, incident records, receiver acceptance, and Metrc reconciliation belong to the transport lifecycle.

Each event should be authenticated and tied to the same run.

Layer 4: payment at the defined boundary

AeroPay or another payment rail should be invoked according to the business/payment workflow—such as preauthorization at booking and capture at the approved delivery boundary—not because a barcode was read.

That separation reduces the blast radius of change and makes failures easier to diagnose.

Frequently asked questions

Should the scanner call Metrc directly?

The capture layer should hand the normalized identifier to the platform verification layer, which applies the correct Metrc/load context.

Should a scan trigger payment?

No. Payment belongs to its own defined booking/delivery workflow.

Why separate the layers?

It allows one component to be upgraded or repaired without unnecessarily risking unrelated compliance, transport, or payment functions.
