I am trying to see how we can see who signed up for our courses in Skilljar and those who have not. Seeing that the integration API key is deprecated, so wondering if there is a workaround or code we can use to push that info to show in a contacts properties
Hi, @DLee23 
thanks for your question. Have you looked into using Private Apps or OAuth and a Public App? Either will allow you to provide authentication when using our APIs. Additionally, do you have a link to the Skilljar documentation for setting up authentication? This might help give our community more information.
Best,
