In the tab "Actions" of a Liferay Objects item we can
configure a trigger about a Webhook with a payload.
I didn't find any documentation about this Webhook.
When i create a new Webhook action I have two fields: "URL"
and "Secret".
The most obscure for me is the Secret field.
Moreover I'm not able to understand which payload is transported and
especially in what data format.
Thank you in advance for some help.
