In this 11 minute video I use PowerApps and Flow to scan a book’s barcode, connect to the Google Books API to pull book information (title, thumbnail image, etc). I also provide an Amazon link to the book from within the PowerApp. This demonstrates the live barcode reader in PowerApps and using the (experimental) call to the device’s native reader, which makes a really satisfying “beep” on an iPhone.
