Iterate on product's variants

[hvmzx]

Hi,

I have a product page with multiple variants and would like to iterate on them, and then add those variants if a change was detected on them (text crossed -> uncrossed), (disabled -> enabled) whatever it may be.

Is this something doable, and if it is, how can I dynamically add them to the fields in my json for the notification as I never know in advance how many variants might be in stock for me to iterate over so I can have 1 field, or 5 fields.

Thanks in advance !
