To use Apple Pay outside of the Unzer Direct payment window, you will need to exchange certificates with Apple.

The following will guide you through the setup.

Create an Apple Pay key and download a CSR (certificate signing request) through Unzer Direct.
Go to Settings > Acquirers > Clearhaus. Below the Apple Pay switch, you will find a link to create a certificate.
In the next menu, select Apple Pay as the type and enter a description of the new key.
After the key is created, click it to see the details and download the CSR.
Make sure the CSR values are correct before downloading them.
On the Apple Developer site, go to the iOS certificate page and upload the CSR downloaded from Unzer Direct.
You can now download a certificate from Apple.
Back to the key details in Unzer Direct - upload the newly downloaded certificate from Apple

You can now receive Apple Pay payments directly through your own iOS app.
