In order to create passes, you will first need to create a wallet template for your campaign. Templates establish the structure and appearance of your passes so that when creating passes you just need to personalize them for one or more unique or non-unique users.
Wallet Templates outline the fields which you can modify. These are determined based on the application in which the passes will be used. That is, a wallet Template is an outline of how the Pass will appear on the IOS or Android device before sending the pass to your customers.
