SDK Initialization
License Key
In order to run the Scanbot SDK within your production app, you must purchase and use a valid Scanbot SDK license.
Each license key is valid only for a given app bundle identifier. You will be unable to use any of the SDK features if the license key is corrupted, expired, or invalid in any other way.
Trial License
The Scanbot SDK will run without a license for one minute per session! To get a free, "no-strings-attached" 7-day trial license, please submit the Trial License Form on our website.
Please kindly note that a trial license can only be used in a development and staging environment. You are not allowed to publish your app to the App Store, Play Store, or any 3rd party Android App Store with a trial license.
Purchase a Production License
To get pricing information and purchase a production license for the Scanbot SDK, please request a quote.
App Identifier
Every app has a unique identifier (sometimes also known as "bundle identifier" or "application ID"). Your license will be bound to this identifier. To request a trial license or purchase a production license you have to provide us the bundle identifier of your app.
Initialization
We provide free "no-strings-attached" developer support for the implementation & testing of the Scanbot SDK. If you encounter technical issues with integrating the Scanbot SDK or need advice on choosing the appropriate framework or features, please visit our Support Page.
The Scanbot SDK must be initialized before usage. Make sure to run the initialization as early as possible.
We recommend implementing the initialization in the Application
class of the Android app, and in the AppDelegate
class of the iOS app.

Furthermore, for Android, it is highly recommended to add the flag LargeHeap = true
to the Application
attribute on the MainApplication
since image processing is very memory-intensive.
Updating the License in Production Apps
To renew an expired license or extend a valid license with new Scanbot SDK features, you will have to update your app in the App Store / Play Store. The expiration date and the feature list of a license are contained in an encrypted data part of the license key string. This means a renewal or extension of a license will cause a new license key string to be generated.
License Checks in Production Apps
If your Scanbot SDK license has expired, any call of the Scanbot SDK API will terminate your app.
To prevent this you should always check for license expiration during the runtime by calling the method IsLicenseValid()
.
If this method returns false
, you should disable any usage of the Scanbot SDK functions or UI components.
We highly recommend implementing a suitable handling of this case in your app!
Example code for checking the license status:
if (ScanbotSDK.MAUI.ScanbotSDK.IsLicenseValid)
{
// Making your call into ScanbotSDK API is now safe.
// for e.g.
// ScanbotSDK.MAUI.ScanbotSDK.ReadyToUseUIService.LaunchDocumentScannerAsync(..),
// ScanbotSDK.MAUI.ScanbotSDK.SDKService.ApplyImageFilterAsync(..), etc.
}
Logging
When initializing the Scanbot SDK you can enable or disable logging of the SDK.

- Android
- iOS
On Android logs are printed into LogCat as well as saved on the device. You can find them in Environment.getExternalStorageDirectory()/debug_logs/[package_name]
. Usually it is /sdcard/debug_logs/[package_name]
.
You can also set EnableNativeLogging
to true, to enable C++ logging for low level debugging.
On iOS all logs are printed to the console. There will be no log files created by the Scanbot SDK.
While it may be useful for development, consider switching logging off in production builds for security and performance reasons!
Image Quality / Compression
SBSDKConfiguration
has two more optional properties that specify the image storage format and compression for temporary images. Temporary images are all images created by the document scanner, cropping UI, as well as all image manipulation functions like ApplyImageFilter
.
