I’m doing a Library management system and I need to create a special ACF field that has a textfield and a button. The user inserts an ISBN number (book id) on the textfield, clicks the button and make an ajax request to a server. If the server finds information about the desired book, other ACF fields are filled (author, title, etc).
Is this possible? Where on the ACF Documentation I can find information to develop a field that behave likes that? (make ajax request and manipulate other fields)
