Following this very limited guide,
I was able to get the example shown working with GraphQL and Insomnia.
There is nothing about creating a REST app, so I tried that.
I see I was given similar URL for REST API like the image in the Wiki shows.
I plug the URL into the Insomnia application like the previous GraphQL, and clicked “Send,” but something not expected in the display window.
Page Not Found
The page you are looking for could not be found. Check the address bar to ensure your URL is spelled correctly. If all else fails, you can visit our home page at the link below.
Checking the directory structure, I clearly see no such directory exists.
Far as it gets is /var/www/html/admin/api/api.php
Is something wrong? A bug, or what?
