input and output connetor ?

hey everyone,
please i wanna know what’s the difference between an output connector and an input connector !
thank you.

A “connector in” for a task will execute when that task is initiated, and a “connector out” for a task will execute when that task is terminated.

Relevant documentation: https://documentation.bonitasoft.com/bonita/7.8/connectivity-overview

And to add a clarification to this good answer, there is no “input or output connector” : you have a connector in as explained by “rtumminelli_134599” and each connector has got inputs and output (in its definition)

And to add precision, the behaviour is a bit different between human and service tasks.
On a human taks, a connector in will be executed after contract execution, business variables initialization.
A connector out will be performed after form submission, contract update and operations execution.
