API call through Onload of a catalog form

[Rahul84]

Hi Developers/ @Ankur Bawiskar 

This is related to one of the tricky requirement which I need to build.

I need to call an API on the load of a catalog form and the response I need to store in one of the catalog form field which is a drop down options field.

Please let me know how I can achieve this type of requirement.

Step by Step explanation would be helpful and also a type of sample code.

Thanks in Advance !!

1) onLoad catalog client script with GlideAjax

2) then add the choices via g_form.addOption()
