Add the License Key

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

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 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 iOS) 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, read our What Is a Bundle ID? guide first.

  4. Click next and confirm your selected bundle ID. 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 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 iOS) 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

It’s important that you set the license key before using any PSPDFKit API. During initialization of your widget, register the license key like this:

// To set the license key for both platforms, use:
await Pspdfkit.setLicenseKeys("YOUR_FLUTTER_ANDROID_LICENSE_KEY_GOES_HERE", "YOUR_FLUTTER_IOS_LICENSE_KEY_GOES_HERE");
