Confirm the machine interface
Send the controller label, wiring photos, and the action the machine must perform.
项目适配
适用场景
买家信号
- Vending machines with an MDB controller or cashless harness.
- 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.
首先需要提供
- 机器照片或现有主板照片
- 接口或接线说明
- 支付/API 后要触发的动作
- 是否需要数据上传
不适合的情况
- 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.
集成方式
从 API 指令到机器动作
你的支付系统或后端确认后调用 QuLink，板子执行机器动作并把结果返回。具体接口在样品上确认。

控制流程
从机器接口到 API 控制的执行结果。
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.
API 示例
服务器命令或 webhook 示例。
命令字段取决于机器接口、固件配置，以及由支付还是你的应用触发。
POST /v1/devices/VEND-01/commands
{
"command": "vend",
"slot": "B04",
"reference_id": "ORDER-1001"
}
项目询盘
先发机器照片，我们帮你判断主板、接口和样品测试步骤。
发送机器型号、控制器照片和目标动作，我们确认 MDB 控制板 的接口路径和样品测试步骤。
一条有效的第一条消息
如果不确定机器接口，先发你手上的资料即可。照片往往比长文档更快判断方向。
- 机器类型和目标国家
- 机器照片、主板照片或线束照片
- 支付或 API 后要触发的动作
- 是否需要数据上传、预计数量
最快的第一步
- 发送机器照片
- 说明 API 或支付后要触发什么动作
- 告诉我们是否需要数据上传
常见问题
打样前通常会问的问题。
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.
