Introduction

What a VARIO Cloud App is, how it integrates with the ERP, and how a private App becomes public.

A VARIO Cloud App is an external web application that you build and host yourself. It is integrated into VARIO-Cloud in three ways:

• UI integration: VARIO Cloud embeds your App inside an iframe at defined integration points (for example, as a navigation entry or dialog). To the end user, the App appears as part of the ERP UI.
• Data integration via REST API: Your App talks to the VARIO Cloud backend using the public REST API (secured with OAuth2) to read and update ERP data.
• Webhooks: You can send and receive Events triggered by the Cloud App or via Webhooks

The App does not run inside VARIO Cloud itself. Instead, it is a self-hosted service that connects to VARIO Cloud through iframe-based UI integration and the REST API.

App types: private vs public

VARIO Cloud supports private Apps and public Apps. Every App starts out private — public is a status an existing App is promoted to, not a separate kind of project.

Private Apps

Private Apps are built for a single customer or organization.

• Any customer on the Enterprise plan can develop and add private Apps.
• Private Apps are not listed in the App Store.

Public Apps (App-Store)

Public Apps are available to all customers via the App Store.

You do not need our approval to start. Build and run your App as a private App first; when it is ready for a wider audience, it goes through these steps:

1. Contact us with your finished private App.
2. Sign the App Store contract.
3. Review process — we review the App, and on success it is published as a public App in the App Store.

Because the path always starts private, nothing about the development work changes when you plan to publish later. Build it the normal way — see Create an App and the Quickstart.
