Get notified when a jira custom field is updated with new option (Multiselect field)

Question

Hi Everyone,
I am working on an automation which will create Applications & environments in Apwide (Go-live , Jira plugin) .
I want this automation to work when a jira custom field is updated with new option .
for instance , I have a field called "Application/System" with few options , when a new option is added to this field , I want to automate the process of creating the same application in Apwide Go-live plugin. I have the webhooks available for "Create" api in Apwide , I have been stuck on how to get notified when a jira custom field is updated .

Could someone check & share your insights please.

Thanks in advance .

You will not be able to do that through an automation rule. There are apps in the Atlassian Marketplace where you can connect to external sources for the list of values in your custom field. But not in native Jira.

Hi John , 
I am not going to change the value of field in issue , instead adding a new option to the custom field . 
Eg: application --> has [x,y] 
I want to get notified when this application field is updated with new option [z] .

Thanks .
