I didn't see anything in the documentation so I don’t think this is possible, but I want to confirm.
Is there any way to have a background process run without there being a Banno Card displayed?
I’m currently creating a way to notify the user that they aren’t enrolled in e-statements. However, I would need there to always be a Banno card (plugin) displayed so that the program uses the API and generates a popup when the user logs in.
If possible I would like to be able to "hide" the plugin so that the process is ran in the background.
Is this possible?
No, it is not possible to run a background process within the Banno UI as you have described.
It’s possible to run processes outside of Banno itself and still use Banno’s APIs (see answer to Consumer API - Using Authentication Framework via a "background" service), but that is different from what you are looking to do.
