The Tag Groups plugin does integrate with the WordPress REST API, however the features below are still considered experimental and not officially supported.
Please be careful with all operations that change data. There will be no confirmation dialog. To be on the safe side, make a backup of your database before you start and test first with non-critical sample data.
POST and PUT requests are handled by WordPress interchangeably.
If you use a client like Postman or RESTED, send the attributes as URLencoded form data (Header: Content-Type application/x-www-form-urlencoded) and use Basic Auth with your application password, available in WP 5.6+ or via 3rd-party plugins (untested and unsupported).
Permissions to create or edit groups can be changed in the Tag Groups Settings (Pro version only).
Add the routes after your site URL. In GET requests you can simply add the arguments as parameters. Any returned data will be JSON-encoded, if applicable.
