Have you heard about External Services, Salesforce's functionality that lets Awesome Admins build Flows that integrate with third-party cloud products? OpenAPI schemas are prewritten code provided by 3rd parties, a lot like the "widget" code you might copy & paste to embed a YouTube video, Spotify player, or Bandcamp album into a web page. You can use these "schemas" to teach Salesforce to talk to external cloud services and supercharge the Flow Builder user interface, making it possible for Awesome Admins to: - send text messages - display related YouTube videos next to Cases - read scanned documents with OCR - and more!
