What is the proper url format to send website url to ping services

Been a long time since I have done this, and I completely forgot:

Is this a proper format to send a website sitemap to Google?

https://google.se/ping?sitemap=
What about this to a blog servers?

http://ping.weblogs.se/ping?sitemap=


Thanks

I believe it is:
https://www.google.com/ping?sitemap=
Taking this directly from googles site:
https://developers.google.com/search/docs/advanced/sitemaps/build-sitemap
Sitemaps >> Build and submit a sitemap

Hope this helps!
