Hello everyone,

We are working on integrating our SaaS platform, with an Anviz access control system for one of our clients. They have **C2 KA keypads** and an **SC011 control board** installed.

### **The Challenge**

Our goal is to **synchronize access codes in real-time** between our platform and these keypads. However, we have encountered some limitations:

1. The keypads **cannot be connected to CrossChex Cloud** , which provides an API for user code management.
2. The client uses **CrossChex Standard**.
3. We received an **SDK from Anviz** , but it appears to be designed for **.NET applications** , while our tech stack is **Node.js and React.js (JavaScript).**

### **What We Need Help With**

- Is there a way to **connect directly** to the C2 KA keypads or SC011 controller from a **Node.js** application?
- Does CrossChex Standard expose any **local APIs, database, or other integration points** that we could leverage?
- Has anyone successfully integrated **CrossChex Standard** with third-party software using **JavaScript, WebSockets, or other communication protocols**?
- Are there **alternative methods** to push access codes to these devices without using the .NET SDK?

Any insights, documentation, or experiences would be **greatly appreciated**. Thanks in advance for your help!

Best regards,  
Iván

Hi

The CrossChex Standard is on site software. The CrossChex Standard can not an A CS-based software system. We suggest you can create a server service and call our SDK in the server service. Base on the created server you can control our terminal directly.
