I am trying to build an embeddable widget, with WordPress as the server. I have products and I have created my WP API endpoints where I can
curl them and get my JSON back.
I have an existing structure from our old system I am piggybacking on for now until phase two, so there is an embedded script already that will be one of my endpoints.
When that gets pinged, I am verifying privileges etc, but need to “return” a loader/utility script to pop into the head of the site calling it so that it can handle the rest of the API calls etc.
I cannot for the life of me figure out that part though, how to get that script to return and be added to the DOM instead of returning JSON like normal.
I hope this makes sense, any input?
