Hi @nschutz ,
I wanted to check in and see how you went with this, apologies that this has been sitting around in the community for a while, it appears to have everyone stumped!
I have had a look at the API documentation https://lor.instructure.com/docs/api/#api-Resources-ImportResourceLatestVersion and it states 'A successful import will partly rely on the user having the proper permissions in Canvas to import resources into the Canvas course.'
Therefore, if you had administrative permissions, I would *anticipate* that the call will complete successfully. There are a few things you may wish to check such as which user the content was 'created' by after the import. I certainly anticipate from reading the documentation that you could achieve this.
Please let us know how you have progressed with this, I would be happy to help you out further!
Hope that helps!
Stuart
