Using a LTI protocol, Is there any way to known the user (student) how "consume" the tool once authored?
I mean, actually send a url like param to launch_presentation_return_url like “rich editor” and the TC request a simple GET, I was waiting a POST like the rest of LTI reqs? Any resource/recommendation in order to obtain more information around user in this point?
Thanks
