finnhub.io is a RESTful API. On their signup page, the provide an API Key, and a Secret, but they are asking for a URL for a "WebHook". I don't know what to fill in there.
What do I need to build in Lazarus to provide a "WebHook" ?
Assuming I wanted to set up a test bed in Postman... what wd the "WebHook" URL be?
