# Nexgo OTP

This guide details the specific steps required to prepare your NexGo terminal for API integration.

### Generating the OTP (One-Time Password)

The OTP is a temporary pairing key required to authorize the connection between the Payrexx Cash Register API and your physical terminal.

**Step 1: Access the Main Menu** Ensure the terminal is powered on and connected to the internet. Locate the hamburger menu icon **(≡)** in the top-left corner of the display and tap it to open the navigation sidebar.

**Step 2: Select Connection Mode** The side menu contains various options for transaction history and settings. Tap on the option labeled **"Connect to cash register"**.

**Step 3: Retrieve the Pairing Code** The terminal will transition to a status screen displaying an alphanumeric code (e.g., `QP3U58`).
