# Connect apps

fulfillmenttools offers multiple apps to help you manage your store operations. Our main app is the [Store Operations app](/documentation/apps/store-operations-app.md).

The fulfillmenttools app portfolio comprises a range of apps tailored to different application areas and operating systems. The following apps are offered:

* [Store Operations Android app](https://play.google.com/store/apps/details?id=com.fulfillmenttools.storeoperations)
* [Inventory Android app](https://play.google.com/store/apps/details?id=com.ocfulfillment.inventoryapp\&gl=DE)
* [Returns Android app](https://play.google.com/store/apps/details?id=com.ocfulfillment.multiplatform.app\&gl=DE)
* Returns iOS app

A fulfillmenttools app can only work if it's connected to a tenant via the Backoffice. An app can only be connected to one tenant at a time.

## Connecting an app to the Backoffice

{% stepper %}
{% step %}
**Download and open the app**

Download the app from the App Store or Google Play Store and open the app.
{% endstep %}

{% step %}
**Grant camera access**

Tap **Allow camera access** to enable your camera for the app. You can only access the app when camera access is active.

This will open the camera in the app.

{% endstep %}

{% step %}
**Open Backoffice to get the QR code**

Log in to Backoffice, select either view (if you have permissions to choose), and click **Apps and connections** in the page footer. This will show you a QR code that lets you pair your phone app with your tenant.

{% endstep %}

{% step %}
**Scan the QR code**

Use the app on your phone to scan the QR code displayed in Backoffice.

{% endstep %}

{% step %}
**Log in**&#x20;

After scanning the QR code, the app connects to the tenant and redirects you to the login screen. Input your credentials and tap **Log in**.

Using an outdated app version displays a screen that informs you of a version mismatch and prompts an update.

## 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://docs.fulfillmenttools.com/documentation/apps/connect-apps.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.
