RE: Create a greeting with data from Google BigQuery

You can access any web service using a Self script.
See,
https://www.botlibre.com/forum-post?id=13020078

For a greeting you can use a "redirect" or "srai" template to redirect to a script.
i.e.
Template("{redirect "call bigquery"}")

Then you have a script like,

state Greeting { pattern "call bigquery" answer callBigQuery(); function callBigQuery() { var json = Http.requestJSON(...); ... }
