How to trigger outbound REST API when State is change?

[jackh]

Hi,

My use case requires to call external REST API from ServiceNow when the incident state is changed.   For example, our release pipeline will create a new incident (via inbound REST API call) for someone to approve this release.   Once the incident assignee approves the ticket by changing the State (e.g. from New to Approved), it will trigger to call outbound REST API to our release pipeline.   How to do that in ServiceNow to trigger such outbound API when State is changed?

Any advice would be appreciated.

Thanks

You can have onChange client script on state field and check if the new State is APPROVED, then call the script include from client side

in Script include, you can have script for your outbound REST web service

Please allow me to ask a silly question. Where can i see such onChange code for my UI?

I did not understand what do you mean by "onChange code for my UI?"

But you can find client scripts under 'System Definition' and filter the Type as onChange, you can see lot of example scripts
