Is it possible to fill several sites from one WordPress admin panel?

Question

WordPress

Interested in the possibility of simultaneous placement of publications on several of their sites. So that each time you do not go separately to the admin panel of each site, but once at once for all. I've never experienced anything like this, but maybe someone more experienced knows. Is this possible with WordPress?

Answer 1

You can, of course.
Leverage the power of the WP REST API.
Roughly speaking, choose the main site. Next, add a form for publishing posts in it, or hang a new hook on the button for publishing a new post. In function.php, process and publish posts on other sites through the WP REST API.
Maybe WordPress Multisite can help you with something, but in this case you still need to publish articles for each site, it’s just convenient to switch between admin panels
