What to send first

Machine photo or existing board photo
Interface or wiring note if available
Target action after API command or payment
Whether telemetry or data upload is required

Integration model

Payment confirmation becomes a vend action

QuLink maps a QR payment or server approval to a machine-side vend command, relay output, MDB action, or custom controller workflow.

Machine interface: MDB, relay, serial, cabinet controller, custom vending wiring
Trigger source: QuLink QR payment, wallet callback, app approval, or server command
Data returned: vend.result, payment reference, machine fault, telemetry, online status
Project mode: retrofit payment board, smart retail rollout, OEM vending controller

Workflow

From machine interface to API-controlled result.

Identify vending interface

Confirm MDB, cabinet controller, relay, serial, or custom board wiring.

Map payment to product

Define QR code, product slot, price rule, payment reference, and timeout behavior.

Trigger vend

QuLink sends the vend action after payment or server approval.

Upload result

Your server receives vend success, failure, status, and telemetry events.

API example

A clear server command or webhook for the machine-side action.

The exact command fields depend on machine interface, firmware profile, and whether payment or your own app triggers the action.

{
  "command": "dispense",
  "source": "qr_payment",
  "machine_action": {
    "interface": "vending",
    "slot": "B12"
  },
  "reference_id": "QR-ORDER-208"
}

FAQ

Questions buyers usually ask before a sample test.

Can this work without replacing the full vending machine?

Often yes. The first step is checking whether the machine can accept MDB, relay, serial, or cabinet-controller commands.

Can we use our own wallet or checkout?

Yes. Your checkout can approve payment and call the QuLink command API.

Can the board report vend results?

Yes. The project can include vend success, failure, online status, and fault upload.
