Display posts from a single category
To display posts from a single category you will need to enter the ID number for that category. WordPress does not by default display this ID’s in wp-admin. We recommend using a free plugin like Show IDs by Robot 99 Link. Once installed navigate to Posts > Categories and the ID will be visible.
Troubleshooting
Make sure your WordPress is up to date and that your public API is turned on( it’s enabled by default ), and CORS is enabled. You can enable CORS with the following plugin https://wordpress.org/plugins/http-headers/
