Our school system (zermelo) didn’t have an app (only a sluggish web app). So I wanted to see if I could make a proper iOS app for it. I first looked for any documentation on their API, which thankfully existed (unlike with magister…). I saw that their api is very simple to work with.
After that, I first tried fetching and showing the schedule in a simple react app. After finding out that their authentication method was requesting an access token by providing the Zermelo api with a code that shows up in the Zermelo dashboard, I was very surprised, I expected them to require me creating an application in some developer dashboard.
