There are 3 settings that need to be added in the AtBot Admin Portal to set up your bot's integration with QnA Maker. After you create a QnA Maker service click the View Code link on the record in QnA Maker.
Answers coming back from QnA Maker support Actionable Answer syntax. This means that within your Knowledge Base, you would include the :: syntax to create buttons throughout your answers.
AtBot will use some specific metadata values in your KB answers to perform actions specific to AtBot.
keywordmetadata property to your answer will trigger that keyword-based skill immediately after the answer is given. This is a good way to send something like "Did I answer your question?" with prompts to the user and a way to follow up if they select no. The skill must be added to a category in the bot.
