Add a License Key

PSPDFKit for Windows is a commercial product and uses a license key to verify your copy against the package name you registered.

Alternatively, you can initialize the SDK in trial mode without a license.

Generating the License Key

To use a PSPDFKit license with your app, you have to generate a license key and bind it to the applicationId bundle ID of your app.

  1. Log in to the PSPDFKit Customer Portal using the credentials you received when purchasing PSPDFKit. You’ll see the list of all your purchased licenses.

  2. Locate your license (e.g. PSPDFKit for Windows) and click the Assign license key button next to it. A dialog will open.

  3. Enter the bundle ID of your production app. If you’re unsure about this step, please read our What Is a Bundle ID? guide first.

  4. Click next and confirm your selected bundle ID. Please double-check that the chosen identifier matches the one configured in your app, as it can no longer be changed once it’s been set.

Getting the License Key

  1. Log in to the PSPDFKit Customer Portal using the credentials you received when purchasing PSPDFKit. You’ll see the list of all your purchased licenses.

  2. Locate your license (e.g. PSPDFKit for Windows) and click the License Key button next to it. If there is no such button, you probably need to generate the license key first.

  3. A dialog will open showing you a code snippet with your license key.

  4. After copying the license key over to your project, the PSPDFKit SDK will be ready to use.

Adding the License Key

This can be done either when initializing a PdfView, or through the Sdk.Initialize method, and it only needs to be set once after the application starts.

In XAML, when integrating the PdfView control, you can use its License property like so:

xmlns:pspdfkit="using:PSPDFKit.UI"

<pspdfkit:PdfView License="YOUR_LICENSE_HERE" ... />

In C#, use Sdk.Initialize:

PSPDFKit.Sdk.Initialize("YOUR_LICENSE_HERE");

The initialization call placement depends on your application’s structure, but you must make sure that it’s called before any PdfViews are loaded in or any model-only methods are used.

Trial Mode

For the trial experience, you can initialize the SDK without a license. This can be done by either omitting the License property of the PdfView in XAML, or through the manual call:

xmlns:pspdfkit="using:PSPDFKit.UI"

<ui:PdfView />
PSPDFKit.Sdk.Initialize();
