PUT    /api/posts/{id}         # Update post (full)
PATCH  /api/posts/{id}         # Update post (partial)
DELETE /api/posts/{id}         # Delete post

GET    /api/posts/{id}/comments    # List post comments

API Resources and Collections

Basic Resource

<?php

namespace App\Http\Resources;

use Illuminate\Http\Request;
use Illuminate\Http\Resources\Json\JsonResource;

class PostResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     */
    public function toArray(Request $request): array
    {
        return [
            'id' => $this->id,
            'title' => $this->title,
            'slug' => $this->slug,
            'excerpt' => $this->excerpt,
            'content' => $this->when($request->user()?->can('view', $this->resource), $this->content),
            'status' => $this->status,
            'published_at' => $this->published_at?->toISOString(),
            'created_at' => $this->created_at->toISOString(),
            'updated_at' => $this->updated_at->toISOString(),
            
            // Relationships
            'author' => new UserResource($this->whenLoaded('user')),
            'comments' => CommentResource::collection($this->whenLoaded('comments')),
            'comments_count' => $this->when($this->comments_count !== null, $this->comments_count),
            
            // Links
            'links' => [
                'self' => route('posts.show', $this->id),
                'author' => route('users.show', $this->user_id),
            ],
        ];
    }
}
