Hello, I have been created a custom field in order section like a text. I would like when customers starting to type to load information data from external json file on root joomla directory? How can I do it?

Hi,

You can add custom javascript code for that and target the input field with an addEventListener.
You can add your custom javascript code in the show_block_field view file via the menu Display>Views of HikaShop.
