Hello,
I created ASP.Net Core MVC app that accesses Moodle platform. I used LtiLibrary.NetCore library to create Lti request. I registered app as Moodle External tool and added Consumer key and Consumer secret. It works okey, i got data from Moodle, but my question is necessary to validate consumer key and consumer secret from Moodle. Can anyone explain me Lti requests and what to do with validation?
