Confused on how to approach this project

Hi everyone,

I’ve been tasked by management at work to develop a mobile application to communicate with some custom hardware we manufacture. The app would be responsible for collecting history data and uploading it to a database on the customers premises using an api we develop.

Has anyone ever worked on a project like this? The only keywords I can find is hybrid SaaS approach, but I am still confused how to tackle this.

How would I handle user log in with different customers/companies and knowing what url their api is hosted on and configuring that within the app.

Any help or advice is greatly appreciated!
