I'm a bit confused now, with SCORM you would be talking to an API file with JavaScript to pass get and set variables, there's no JSON in SCORM. If you're talking to an LRS using the xAPI then that's a different matter, for it DOES use JSON for its data stream. It seems you're talking apples and oranges here, has anyone actually communicated with a SCORM API to pass Construct 3 game data to an LMS????
