When an event occurs, a reaction follows.

You could also say: "an event here will certainly trigger a reaction."

  • reaction - (noun) - "the way someone acts or feels in response to something that happens, is said, etc." Merriam-Webster "a response to a stimulus" TFD

Another choice would be: "a response"


"Trigger" (verb meaning to cause) is a word we commonly use in software engineering.

The occurrence of event X triggers action Y


The occurrence of event X triggers event Y

"reaction" is another synonym, although it has a more general purpose and does not necessarily imply a procedural standard action taking place. It is also widely used to refer to natural reaction or instinct.


A response is a general term

A reaction to something:

an extended, jazzy piano solo drew the biggest response from the crowd

an honors degree course in Japanese has been established in response to an increasing demand
