# Create an App

### Creating a new App and getting API credentials  <a href="#creating-a-new-app-and-getting-api-credentials" id="creating-a-new-app-and-getting-api-credentials"></a>

Start in the VARIO Cloud Admin-Center: [https://admin.vario.cloud](https://admin.vario.cloud/)

#### Step 1 – Open the Developer Menu (This has to be activated for you by the VARIO AG)  <a href="#step-1-open-the-developer-menu-this-has-to-be-activated-for-you-by-the-vario-ag" id="step-1-open-the-developer-menu-this-has-to-be-activated-for-you-by-the-vario-ag"></a>

1. Sign in to the VARIO Admin-Center.
2. In the left-hand navigation, select **“Entwickler”** (Developer).

This opens the Developer view where you see a list of your existing Apps.

#### Step 2 – Start the “Create App” dialog  <a href="#step-2-start-the-create-app-dialog" id="step-2-start-the-create-app-dialog"></a>

1. In the Developer view, locate the buttons in the header toolbar on the top right.
2. Click **“App erstellen”** (Create App).

A dialog titled **“Neue App erstellen”** (Create new App) will open.\
It contains a single text field labeled **“App-Manifest”**.

#### Step 3 – Paste the App manifest  <a href="#step-3-paste-the-app-manifest" id="step-3-paste-the-app-manifest"></a>

To define your new App, you must provide a valid **App manifest** in JSON format.

1. Prepare your manifest JSON locally.
2. Paste the JSON into the **App-Manifest** field.
3. Click **“Anlegen”** (Create).

**EXAMPLE APP MANIFEST**&#x20;

```json
{
  "appVersion": "1.0.0",
  "label": "Demoapp",
  "description": "Just a demo app",
  "shortName": "demoapp",
  "rootUrl": "https://app.example.com/",
  "pcInstallationUrl": "https://app.example.com/ui/install.html",
  "pcInstallationDeletionUrl": "https://app.example.com/ui/uninstall.html",
  "pcManifestUrl": "https://app.example.com/manifest",
  "requirements": {
    "licenseKey": "app_demo_license_key",
    "permissions": [
      {
        "resource": "crm-activity",
        "verb": "read"
      },
      {
        "resource": "crm-activity",
        "verb": "create"
      }
    ]
  },
  "authorizationVerbs": [
    {
      "verb": "use-app",
      "description": "Allowed to use the demo app"
    },
    {
      "verb": "add-activity",
      "description": "Allowed to add activities"
    }
  ],
  "uiIntegrations": {
    "integrations": [
      {
        "pointOfIntegration": "navigation.root",
        "id": "demo-page",
        "url": "https://app.example.com/ui/demo.html",
        "iconClass": "fal fa-atom-simple",
        "msgKey": "Demoapp",
        "permissionKey": "use-app"
      },
      {
        "id": "demo-dialog",
        "url": "https://app.example.com/ui/demo-dialog.html"
      },
      {
        "id": "demo-vr",
        "url": "https://app.example.com/ui/demo-vr.html"
      }
    ]
  }
}
```

At this point, you have defined:

* basic App metadata (`label`, `description`, `appVersion`)
* licensing and visibility (`uniqueLicenseKey`, `privateApp`, `dedicatedApp`)
* URLs for the App backend and UI (`rootUrl`, `pcInstallationUrl`, `pcInstallationDeletionUrl`, `pcManifestUrl` )
* required **permissions** for the APP (access to the activity table in this case) under `requirements.permissions`
* custom **authorization permissions** that can be assigned to users
* **UI integrations** (for example, a navigation entry via `pointOfIntegration: "navigation.root"`)

#### Step 4 – Copy your API credentials (AppClient)  <a href="#step-4-copy-your-api-credentials-appclient" id="step-4-copy-your-api-credentials-appclient"></a>

After you create the App successfully, VARIO-Cloud will generate OAuth2 client credentials for this App:

```json
{
  "appIdentifier": "your-app-identifier",
  "clientId": "your-client-id",
  "clientSecret": "your-client-secret",
  "appJWK": "JWK_TOKEN"
}
```

{% hint style="danger" %}
**Important**\
`appIdentifier`, `clientId`, `clientSecret` and `appJWK` are shown **only once**.\
You must copy these values immediately and store them securely (for example in a password manager, a secrets vault, or environment variables used by your App).
{% endhint %}

These values are what you will use later to authenticate against the VARIO-Cloud API (e.g. when requesting OAuth2 tokens) and to verify the APP\_JWK Token.

Once you have copied and stored these credentials, you are ready to continue with authentication (e.g. OAuth2 Refresh Token grant) and actual API calls.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.vario-software.de/documentation/apps/create-an-app.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
