Once your ABM Account has been created, and your apps approved on the App Store, you need to connect your ABM Account with Appaloosa.
To do so, you will need to generate a vpptoken on your ABM Account and upload it on Appaloosa.
Login to your ABM Account and go to Settings and select Apps & Books.
In the right pane, you'll see the section My Server Tokens where you can download your vpptoken.
Click on download to retrieve your vpptoken which is valid for 1 year.
Now, go back to Appaloosa, click on Settings, and select Apple Business Manager.
Upload your vpptoken downloaded from ABM, enter your ABM email and save.
To start distributing your apps with the management features you can follow this guide.
If you want to distribute your apps using redemption codes without management please continue to this guide.
