This document summarizes a presentation about extending PowerApps and Microsoft Flow with custom code. The presentation discusses how PowerApps and Flow can be extended through Azure API Apps, Azure Functions, and notifications. It also covers demoing the addition of custom data sources, extending the PowerApps expression language, reusing Azure Functions in Flow, and enabling two-way communication between PowerApps and Flow. The presentation aims to provide workarounds for limitations in PowerApps' expression language and extensibility through custom APIs, functions, and webhooks.
