Hey @jetisco4u
I usually use the Network requests in the DevTools to figure things like this, so I went to the App Management app with the Network tab open after clicking on All Apps:
You can see the endpoint being used is: https://play.im.dhis2.org/stable-2-39-6/api/39/appHub/v2/apps
You could do the same in the apps.dhis2.org website, you’ll find the endpoint is: https://apps.dhis2.org/api/v2/apps?types=APP
I hope this helps!
