For example, entering /?json=1 into the browser loads the main site html, the same as omitting the json querystring variable: /

The JSON API is activated. I have tried reactivating and deactivating, checking .htaccess file settings, and deactivating all other plugins. None of those have made much difference so far.

• json
• rest-api
• plugin-json-api

• 2 what do you men "json api is activated". the api is part of version 4.7 and there is nothing that needs to be activated – Mark Kaplun Commented Apr 21, 2017 at 16:13
• 1 Touche Mark. But it still doesn't work when the old plugin is deactivated. – n8bar Commented Apr 21, 2017 at 16:19
• 2 the end point is in /wp-json, have you tried it? – Mark Kaplun Commented Apr 21, 2017 at 16:26
• 1 I didn't know that but it gave me a 404 error. however, /index.php/wp-json worked. Thank you!! – n8bar Commented Apr 21, 2017 at 16:34
• 1 if you need the /index.php there is probably something generaly wrong with how permalinks are setup on the site. never saw it myself so not sure what advice to give – Mark Kaplun Commented Apr 21, 2017 at 16:50

I'm likely doing it wrong, but when I form my requests for a Wordpress installation at http://www.example/ like this:

http://www.example/index.php?rest_route=/my/rest/route/here

I end up getting proper responses back.

I had a heck of a time figuring this out and ended up grokking a URL formatted like that in the HTML returned to me. I was expecting to make requests as http://www.example/wp_json/wp/v2/my/rest/route/here , but I only got HTML responses.

I had the same problem and I solved it setting the permalink in the wordpress and also changing the .htaccess (see https://www.wpbeginner/wp-tutorials/how-to-fix-wordpress-posts-returning-404-error/) to make permalink work correctly.

Ok, so the new endpoint for Wordpress 4.7 is mywordpresswebsite.example/index.php/wp-json. It's part of Wordpress Core as of 4.7 and not a plugin anymore, there's nothing to be activated. Thank you, Mark Kaplun.
