I was writing a small software application which monitors websites for changes. If any change in the text, images or other files on a page occurs, the user should be notified.
I was doing it by downloading the entire website at regular intervals, like every minute. But then, I learnt that there are websites and applications which provide this service. Source: https://www.hongkiat.com/blog/detect-website-change-notification/
Now I have been tasked to write this application, so my question is that is there an API which would provide me this service. That is, notify me when the content of a website changes, including text changes, image changes or any other changes? I couldn't find something from my google search but I am a newbie.
