An app parameter is a container for values that are used repeatedly in your application. You can insert an app parameter into a DataPage, authentication, or connection object. It can be edited independently without editing the object where the app parameter is used. Thus, whenever you change a parameter’s value, all objects that contain that parameter use the latest value.
You can access the App Parameters screen by clicking Manage in the App Parameters panel of the App Overview screen.
Here are some examples of how you can use app parameters in your applications:
- If you use the same email address for several notification or acknowledgement emails, defining it as a parameter gives you the flexibility to change it at any time without modifying each DataPage.
- You can create a standard header bar and insert it in the header of all your DataPages. The parameter can be a long text and contain HTML code as well as images, menus, etc. Likewise, if you need a footer or a disclaimer on your DataPages, it can be created as a parameter. You can then insert that parameter into each relevant DataPage footer.
- For developers who build apps with the intention of distributing to multiple customers, you can use parameters to customize each implementation of the app for each of your customers without actually editing the DataPages. Elements such as emails, URLs, logos, names, etc. can be managed as parameters.
