If you just need to create a post with custom post type, WordPress has it's own REST API to create a post. Refer here.

Else if you have certain specific requirements that the default API does not support then you need to create a new custom endpoint. You can find help from here. There you write your logic to authenticate your API requests, creating post with POST data, saving extra field values or meta.
