# Nexgo OTP

Step-by-step guide for generating the Pay-Connect pairing code (OTP) on NexGo N-Series terminals.

This guide details the specific steps required to prepare your NexGo terminal for API integration using the **Pay-Connect** feature of the ELLYPOS terminal app.

## 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: Open Pay-Connect** The side menu contains various options for transaction history and settings. Tap on the option labeled **"Pay-Connect"**.

**Step 3: Retrieve the Pairing Code** The terminal transitions to the **"Connect to Pay-Connect"** screen, which displays a 6-character alphanumeric code (e.g., `F63DJW`).

* **Action:** use this OTP code when sending the pairing request.
* **Note:** If you navigate away from this screen before pairing is complete, the code will change.
