HTTP Callouts

This demonstration shows how to call an exchange rates API using template strings, variables, and JSON traversal. It targets the update of a price list by calculating prices based on a monthly average exchange rate using Streamscript. The process involves setting start and end dates for a month, building a URL with merge fields, and using an HTTP GET command to fetch and return exchange rates from an endpoint.
