Trouble Defining API Schema within API Components

I’m having trouble defining an API schema within Wappler API action settings.

The endpoint I’m working with (FoxyCart front-end API) requires all requests to be sent via HTTPS from a whitelisted IP address / Domain. My computer’s IP address and site domain are both whitelisted and the request works fine on my live site, but I’m getting an error when using the “Define API Schema” feature (within wither server action settings or API action component).

At this point, I’m assuming the requests sent by the Define API Schema/Fetch Schema button aren’t sent over https? Or I need to whitelist a different IP address?

I just need to be able to use the JSON data received in the API response dynamically.

Clarifying questions are, of course, welcome.
