What constitutes "web content" and "authoring tool" for the purposes of the VPAT?

I'm filling out a VPAT for our company's product and having some difficulty understanding the terminology. Our product is an integration tool for flowing data between different systems. The frontend is web-based, while the backend is all JAVA. The tool allows users to create and manage integrations, which are represented in the web UI. Does this constitute "web content", and thereby make our product an "authoring tool"? I've been able to find some definitions of "authoring tool" but not much for "web content". I'm having a really hard time finding out where to draw the line.
