The target of this module is merely for developers in order to create custom APIs and then integrate them to external apps.
OpenCart architecture application separates one API for customer front end and another one for admin front end, so most of the functions are similar but there are some exclusive for admin, and integrating this module you are able to do many possibilities b your risk.

On the other hand, I'll need time to check and fix such error. I had never had such issue before.
