Configure a Machine-to-Machine Application

A Machine-to-Machine (M2M) application is used when one service needs to authenticate with another service without an end user signing in.

Common use cases include:

  • Backend APIs
  • Microservices
  • Cron jobs
  • Background workers
  • Automated processes
  • Server-to-server communication

Quant0 uses the Client Credentials flow for Machine-to-Machine applications.

Authentication flow: Client Credentials

When to Use a Machine-to-Machine Application​

Choose Machine-to-machine when:

  • There is no interactive user login.
  • A backend service needs to authenticate as itself.
  • One service needs to access another API.
  • Authentication happens entirely between trusted services.
  • The application runs as an automated or background process.

Create a Machine-to-Machine Application​

To create a Machine-to-Machine application:

  1. Open the Quant0 Organization Portal.
  2. Navigate to Applications.

  1. Select Create application.
  2. Select Machine-to-machine.
  3. Select Continue.

The authentication flow is:

Client Credentials

Configure Application Basics​

The Basics step allows you to configure the application's basic information.

Application Name​

Enter a name that clearly identifies the service.

Example:

Order Processing Service

Description​

The description is optional.

Example:

Backend service used to process customer orders

Use the description to help administrators understand the purpose of the service.

Configure URLs​

Machine-to-Machine applications do not require an interactive browser authentication flow.

Because there is no end-user redirect involved, the following URL settings are generally not required:

  • Callback URLs
  • Web origins
  • Login entry points
  • Sign-out URLs

Note: M2M authentication happens directly between trusted services and Quant0. No browser-based authentication redirect is required.

Configure Sign-In and Security​

M2M applications do not use interactive user sign-in.

There is no end-user authentication step.

The service authenticates as the application itself using:

Client Credentials

This means:

  • No user login is required.
  • No authorization code redirect is required.
  • No browser session is required.
  • The backend service obtains tokens directly from Quant0.

Review the Application​

Before creating the application, Quant0 displays a Review page.

Review the following configuration:

  • Application type
  • Application name
  • Authentication flow
  • Credentials
  • Access configuration
  • Application group
