# Technical requirements The fulfillmenttools applications have several technical requirements. Additional configurations are necessary when using [Zebra](https://docs.fulfillmenttools.com/documentation/apps/technical-requirements/zebra-hardware-scanner-configuration) or [Honeywell](https://docs.fulfillmenttools.com/documentation/apps/technical-requirements/honeywell-hardware-scanner-configuration) hardware scanners or a [Zebra printer](https://docs.fulfillmenttools.com/documentation/apps/technical-requirements/zebra-printer). {% hint style="info" %} For questions about network setup, permissions, or requirements, contact us using [our support portal](https://ocfulfillment.atlassian.net/servicedesk/customer/portal/1/group/13/create/47). {% endhint %} ## Application-specific requirements ### Android apps (Operations, Inventory, and Returns) * Android smartphone or Mobile Data Entry (MDE) scanning device. * Minimum software version: Android version 8 (API Level 26). * Maximum software version: Android version 14 (API Level 34), which requires application version 1.22.0 or higher. * The application is developed and tested on Google Pixel devices (4a or newer). * A range of MDE devices, such as Honeywell (for example, EDA-52) and Zebra (for example, TC 21 and TC 26), is supported. A list of recommended devices or approval for specific devices is available upon request. * MDE devices may require additional software to be installed and activated so the hardware scanner is accessible by the application. * Devices not managed by a Mobile Device Management (MDM) tool must be able to access [Google Play](https://play.google.com/store/apps) for application downloads and updates. * Alternatively, APK download is possible via the REST API when using a custom MDM solution. In this case, the application is downloaded through a channel provided by fulfillmenttools instead of from Google Play. * Required application [permissions](https://play.google.com/store/apps/details?id=com.ocfulfillment.fulfillmentapp) must be granted on the device. * Ports and URLs for Google Firebase Cloud Messaging (FCM) must be accessible to support push notifications. Refer to [FCM ports and your firewall](https://firebase.google.com/docs/cloud-messaging/concept-options#messaging-ports-and-your-firewall) for details. (Operations app only) * The current version of [Google Play Services](https://developers.google.com/android/guides/overview) must be installed. This is usually present when a Google account is configured on the device. * Ports and URLs for Google Play Services must be accessible. See the [appendix](#appendix). * A stable internet connection or sufficient WiFi signal is required in the entire area where the application is used (for example, 50 Mb/s or Long-Term Evolution (LTE)). The required bandwidth depends on the number of active devices. ### Operations app (web) * The latest version of a modern web browser, such as Google Chrome. * Stable internet connection (50 Mb/s). * Honeywell devices may need a separate license for the hardware scanner to be usable. ### Backoffice * It's recommended to use one of the two most recent versions of a modern web browser, such as Google Chrome. * Recommended minimum screen resolution: 1024x768. * Stable internet connection (50 Mb/s). ### Returns App (iOS) * Apple iOS device with a camera. * Minimum software: iOS Version 14.1, which requires application version 1.2.1 or higher. * The application is developed and tested on iPhone SE (iOS version 14.1 or newer). * Devices must be able to access the [Apple App Store](https://apps.apple.com/us/app/fulfillmenttools-returns/id6477875850) for application downloads and updates. * Required application [permissions](https://apps.apple.com/us/app/fulfillmenttools-returns/id6477875850) must be granted on the device. * A stable internet connection or sufficient WiFi signal is required in the entire area where the application is used (for example, 50 Mb/s or Long-Term Evolution (LTE)). The required bandwidth depends on the number of active devices. ## Android-specific requirements The Android mobile application utilizes Google Play Services and so requires access to the following services: * Firebase Analytics requires access to: * `app-measurement.com/a` * Firebase App Distribution requires access to: * `firebaseappdistribution.googleapis.com` * `appdistribution-uploads.crashlytics.com` * Firebase Authentication requires access to: * `www.googleapis.com` * `firebaseauth.googleapis.com` * `identitytoolkit.googleapis.com` * `securetoken.googleapis.com` * Firebase Crashlytics requires access to: * `*.crashlytics.com` * `*.fabric.io` * `crashlyticsreports-pa.googleapis.com` * `firebasecrashlyticssymbols.googleapis.com` * Firebase Performance requires access to: * `play.googleapis.com` * `www.googleapis.com` * Play Services and Firebase Installations require access to: * `device-provisioning.googleapis.com` * `firebaseinstallations.googleapis.com` ## Hosts and ports To use the applications, the following hosts and protocols must be accessible from the network. Dedicated URLs are used for each tenant. * [Google Identity Toolkit](https://cloud.google.com/identity-platform/docs/use-rest-api?hl=en) service: * `https://identitytoolkit.googleapis.com/` * `https://securetoken.googleapis.com/` * [Sentry.IO](https://sentry.io/) service: * `https://*.ingest.sentry.io/api/` * Operations app (web): * `https://pick--prd.web.app/` * Backoffice: * `https://ocff--prd.web.app/` * REST API: * `https://ocff--prd.api.fulfillmenttools.com/` * GraphQL API: * `https://ocff--prd.graphql.fulfillmenttools.com/` * `wss://ocff--prd.graphql.fulfillmenttools.com/` * Download API: * `https://ocff--prd.download.fulfillmenttools.com/` * Public configuration files: * `https://storage.googleapis.com/ocff--prd-config-public/` ## Supported barcodes for camera scanning The following barcodes are supported when scanning using the camera on an Android device: * `EAN-8 Composite Symbologie` * `EAN-13 Composite Symbologie` * `QR Code` * `Data Matrix` * `Code-128` * `UPC-A` * `UPC-E` * `Interleaved 2 of 5`
