I'm currently trying to build a news reader that gets rss feeds from different google news topics and I found this website that breaks down the url parameters pretty well, but under the topic parameter, the link that it has for a list of topics brings you to this page which says nothing about topic keywords. The only topic key that I've been able to find is tc being the key for the tech topic.
Does anybody know where I could find a list of these topics or if the topic=[topic] parameter is deprecated what I could use instead?
It will depend of country.
Example (for US):
https://news.google.com/news/headlines/section/topic/BUSINESS?ned=us&hl=en
But, if you query other country, the topic will change.
Example (Colombia):
Here is the RSS about economy/business in Colombia:
Check too the ned and hls parameters added.
