# M2M users

### Overview

M2M (Machine-to-Machine) users enable secure API integrations between Dataloy VMS and external systems. These automated users authenticate using client credentials rather than traditional username/password combinations, allowing systems to communicate without human intervention.

### Access Requirements

To create and manage M2M users, you need one of the following roles:

* **Administrator**
* **M2MProvisioning**

### Creating an M2M User

#### Step 1: Navigate to M2M Users

From the main menu, go to **Setup** → **M2M users**

The M2M users page displays all existing machine users with their names and Client IDs.

#### Step 2: Create New User

Click the **"+"** button in the top right corner to open the creation dialog.

Insert a username and necessary security groups.

* **Security Groups**: Current permission assignments
* **Business Units**: Assigned business units

#### Sharing Credentials

Provide the following to your integration partner:

1. **Client ID**
2. **Client Secret**
