and I receive an error message that says:
<err code="103" msg="Request signature (sig param) missing"/>
The URL you're using is missing the "sig" param. The SCORM Cloud API calls are secure methods which require being signed with your AppId's secret key. For an overview, please see: http://cloud.scorm.com/doc/web-services/api.html#ServiceFormat
Usually, API users will start with one of our client libraries (http://scorm.com/scorm-solved/scorm-cloud-developers/) to create a web app, and put their AppId and secret key in the configuration files. The methods in those libraries will generate the necessary "sig" param for an API call.
If you’re still having issues, please send a message to firstname.lastname@example.org. We’re happy to help.
