Get notified of a new listing on certain websites

详细信息

I want to be notified of a new listing on two websites. 1. https://swappa.com/ 2. https://www.mercari.com So when there is anew listing on a certain products, I want to be notified via slack or discord webhook. For swappa, they go item. So I have a dashboard currently and I want to be able to add the items on my dashboard. So in the future I can remove and add items that need to be watched. Mercari, I do a search for a surface, and under that search I want to be notified of a new product. I want to be able to add different searches and remove them from my Dashbaord.
