# Get started

Follow this quick tutorial to make your first API call. In this tutorial, you’ll log a user into IXM One to retrieve their session ID.

### Prerequisites

For the tutorial, you need an IXM One account and the user credentials.

## Retrieve your session ID

To retrieve your session ID, perform the following steps:

1. Access the IXM One API.
2. Go to **Users > Log a user into the system**.
3. In the body, enter your IXM One application name, username, and password.
4. Optionally, enter your Application GUID. If you don’t have one, just leave it as is.
5. Check the response to retrieve your session ID.

An API call or API request is a message to a server that requests an API to provide a service or information.

When you're logged in, you get a session ID that you can use for authorization. The session ID is connected to a user including their rights and permissions.

A standalone application can be identified by a globally unique identifier (GUID). If you are unsure, ask your administrator whether your application requires an application GUID upon login.
