Why is my WP REST API custom post not working?
I’m writing a plugin, and I’m having some trouble with the custom endpoint that takes in data from the front-end of the app (Angular), and will pass it another function to filter some data. I have the GET request to the product database working just fine, but the POST just returns a 404 error (an empty array if I test the endpoint in Insomnia).
Is it correct to return 404 when a rest resource is not found?
Yes, it is pretty common to return 404 for a resource not being found. Just like a web page, when it’s not found, you get a 404. It’s not just REST, but an HTTP standard.
What does it mean to request a rest resource?
But requesting a REST resource and more particularly by a GET method doesn’t mean that the client is about terminating a workflow (that makes more sense with POST/PUT methods). The common use case is to return 204 as a result of a PUT request, updating a resource, without changing the current content of the page displayed to the user.
What does a 404 Not Found client mean?
The HTTP 404 Not Found client error response code indicates that the server can’t find the requested resource. Links which lead to a 404 page are often called broken or dead links, and can be subject to link rot.
How to add REST API support for custom content types?
If you need to add REST API support for a custom post type or custom taxonomy you do not control, for example a theme or plugin you are using, you can use the register_post_type_args filter hook that exists since WordPress version 4.6.0. For custom taxnomies it is almost the same.
How to register custom taxonomy with REST API?
Registering a custom taxonomy with REST API support is very similar to registering a custom post type: pass ‘show_in_rest’ => true in the arguments passed to register_taxonomy. You may optionally pass rest_base to change the base url for the taxonomy’s routes.
How to retrieving data with the WP REST API?

How is a rest request handled in WordPress?
The data structure of a request is conveniently handled by the WP_REST_Request class. This class is one of the three main infrastructure classes introduced in WordPress 4.4. When an HTTP request is made to an endpoint of the API, the API will automatically create an instance of the WP_REST_Request class, matching the provided data.
How does the WP _ REST _ server class work?
When an HTTP request is made to an endpoint of the API, the API will automatically create an instance of the WP_REST_Request class, matching the provided data. The response object is auto-generated in WP_REST_Server ‘s serve_request () method.
