Is it possible to configure Splunk to receive webhook with some information added to it and if it is can you give me link to the tutorial?
Depending on what you mean by webhook - as @_JP already pointed out, Http Event Collector is one of the main and most often used ways of input. Also you can call Splunk using REST to perform various actions - see https://docs.splunk.com/Documentation/Splunk/latest/RESTREF/RESTlist (actually pushing events to HEC is also using one of those REST endpoints).
Yes, you can do this using the Splunk HTTP Event Collector.
Here's a blog post showing an example of Splunk receiving data from a Zoom webhook:
