To get started with Digital Passes you will first need to create a template. This template will hold the design (color, images, etc.) of your passes as well as other settings that determine what information will display on the pass and what functionality it will have. To begin, go to Digital Passes -> Templates in your Main Menu. This page will list all the Digital Pass templates you have created and provide a link for you to update them.
To create a new Digital Pass template, click Create Template. You will give the template a logo, name, description, and select the type of template you are creating. See this article for more details on creating your template.
