Hi @mauricio-souza

Your best option would be to use a script event handler and build an HTTP post which conforms to the system you are integrating to.
Here are some links on how to use the HTTPbuilder

Otherwise, you could customise the meta point to include the value and then only send the meta point on the publisher.
