Is it mandatory to use web scrapper or just logstash to get data from public site

a question asked by many people, in fact is it possible to ingest data from an internet sales website, is it mandatory to use web scrapper or just logstash can be configured to retrieve articles posted on a site in real time. if this is possible plz can you tell me how to do it (plugin or tierce app or configuration)
thank you in advance

I do not think Logstash is the right tool for that. You need a web scraper.

ok so i need a web scrapper then i will wonfigure the logstash to read from the utput of the web scrapper
