How to Insert Gutenberg Blocks Using wp_insert_post
It’s 2023, and we still have no simple way to insert Gutenberg blocks into WordPress using wp_insert_post. You’re out of luck if you want to pull content from an API and insert it dynamically with ease. There are methods like parse_blocks and render_blocks but they still require a lot of messing around to work with. The way Gutenberg blocks work is strange. They’re not stored as an array or structured data in the database. They are stored in the HTML as HTML comments.
