Get more than one author's posts with REST API

Question

http://example.com/wp-json/wp/v2/posts?author=1

gives me author 1's posts.

http://example.com/wp-json/wp/v2/posts?author=1&author=5

gives me only author 5's posts. Is there any way to get 2 different author's posts with one request?

Answer 1

The author parameter in your request, seems to be mapped to the author__in parameter in WP_Query that runs behind the rest-api call here, where a comma separated input:

/wp-json/wp/v2/posts?author=1,5

is translated to an array( 1,5 ) input for author__in.
