Import post from WordPress RSS feed | Gato GraphQL for WordPress

This query imports a post from a WordPress RSS feed, using the title, content and excerpt of the post.

If the author with that username exists locally, it uses it, otherwise it replaces it with the one defined via variable $defaultAuthorUsername.

Variable $url receives the URL of the WordPress single post's RSS feed. It usually is the blog post URL + "/feed/rss/?withoutcomments=1". Eg:

https://wordpress.com/blog/2024/07/16/wordpress-6-6/feed/rss/?withoutcomments=1
