You can create a flash briefing skill if you own, or have the right to distribute, original text or audio content that updates frequently. You should understand web technologies and have the ability to configure HTTPS, RSS and/or JSON content. The voice interactions for a flash briefing skill are defined by Amazon, but you must be able edit the format of your content so that the flash briefing Skill API can understand it.
The first of the Alexa flash briefing options to include is an error message. Alexa will read this to your audience if your briefing is unavailable. Next, you’ll be asked to paste the RSS feed provided by your audio host. The “preamble” field is a short, introductory cue that Alexa will read before delivering your briefing. Finally, fill out any remaining Alexa flash briefing options — frequency, briefing name, category/genre and more — and soon you’ll be ready to launch.
