- Coffee machines that need payment or app approval to start a drink.
- Projects where the existing cabinet and controller should stay.
- Teams that need vend result, fault, or session data in their own backend.
Qué enviar
- Fotos de la máquina o placa actual
- Notas de interfaz o cableado
- Acción objetivo después de API o pago
- Si necesita carga de datos
No es adecuado si
- You need a payment acquirer account or card settlement.
- The machine has no MDB, pulse, relay, serial, or other controllable interface.
- You need a guaranteed compatibility statement before a sample.

Map the command
Define the API command, machine action, result fields, timeout, and fault behavior.
Test one machine
Validate the command, machine action, result, and reconnect behavior on a sample.
Configure the rollout
Confirm connector, firmware, quantity, and support before production.
Ejemplo de API
Ejemplo de comando de servidor o webhook para una acción del lado de la máquina.
Los campos del comando dependen de la interfaz de la máquina, el perfil de firmware y si el pago o la aplicación activa la acción.

Proyecto RFQ
Cuéntanos qué debe hacer, enviar o reportar la máquina.
Envía el modelo de máquina, fotos del controlador y la acción necesaria. Confirmamos la interfaz de Placa de control MDB y el siguiente paso de prueba.
A good first message
If you are unsure about the exact interface, send what you have. Photos often answer more than a long spec.
- Machine type and target country
- Machine photo, board photo, or wiring photo
- Action after payment or API command
- Need data upload? expected quantity?
Fastest first step
- Send a machine photo
- Describe the action after API or payment
- Tell us if data upload is needed
FAQ
Preguntas habituales antes de un test de muestra.
Does QL-MDB-100 replace the existing vending controller?
No. It works with the MDB path exposed by the existing controller. The exact behavior is confirmed on a sample.
Can we keep our own payment provider?
Yes. Your provider or backend approves the transaction, then calls the QuLink API.
What data can it return?
Available vend result, fault, session, and device status fields are confirmed from the machine interface.
What should we send first?
Machine model, controller label, reader or payment module, harness photos, and the target action.
