My problem is:

Hi, is it possible to retrieve the list of options of a select field (for example industries or states ecc) in json format (or any other format) to populate select field of a wp-form placed into a landing pages?

I’m using fluent form and i can create a function in wp to load external data into a select field but i don’t know how to retreive data from Mautic. I didn’t found data I need into the database so i think data is saved on a file into directorys tree.
