How to close modal by using Bussieness rule

[Yuya Toda]

Hi there

I am exploring the way to close the modal by using Bussiness Rule for quite a while now. 

As far as I searched, only cliant script can be used for closing the modal window.

Could somebody help me with this please?

Note: The reason why I want to use Business rule is that I want to close the modal window by the result of the API result(record information)

Thank you for your answering my question.

Let me ask you an additional question.

Does external system  with API linkage to Servicenow make it possible to close modal?

Or is there any way??

Many thanks,

nope.

the modal is UI based and only user can close it or it can be closed from client side code i.e. the same code which opened the modal
