Unfortunately I was unable to come up with a solution so I had to make a workaround. Ideally I still need this to work so I will be trying to figure something out.
There could theoretically be a way to manipulate the custom field’s acf-json file via an automated PHP function like a chron job or something but that will still require the WP admin to sync the fields and do a bunch of other things that are far too complicated for the task I’m trying to accomplish.
I think am attempting to do something somewhat similar, at least behind-the-scenes.
I have an ACF select field that needs its options to be populated via JSON from an external URL’s API return. I have had no luck finding that kind of functionality in the bazillion searches I’ve tried. I’ll follow this thread in case anyone comes up with something.
