POST request on button press / ScriptRunner

[Smacktur]

Hey, everybody!

I have created a custom button in my project (let's say named "Button 1") via ScriptRunner.

What I want:

If the user clicks on this button (in the task), send a POST request to the webhook I specified. It is also important that the payload contains the data of the task.

How to do it through ScriptRunner?

Thanks!
