This post describes a Power App that fetches and displays data from a simple REST API using a custom connector created by importing from Postman. The app also uses a Toggle control to create a While loop in Power Apps.
The app itself can be found here: https://apps.powerapps.com/play/f1478489-b888-4e8a-9fe5-8c244e126e70?tenantId=2e9f06b0-1669-4589-8789-10a06934dc61, but is sadly only available to those with a University of Edinburgh login, as this app is a personal educational project and is not for publication or profit.
Why did this happen?
I’ve recently been working on a project to access our Blackboard Learn Virtual Learning Environment more efficiently using REST APIs. It occurred to me that this might be possible using Microsoft Power Apps, which could allow the development of apps more quickly, if we could get the connection itself figured out. The Dad Jokes app was developed as a proof (or otherwise) of the concept.
