Important: Use this plugin, Not YAML Files

CRITICAL: Always use this HTTP API to manage Craft CMS content. Never directly modify YAML configuration files in the config/project/ directory. The API ensures proper validation, maintains data integrity, and handles all necessary relationships automatically. Direct YAML edits can corrupt your Craft installation.

CRITICAL: The skills plugin must be installed to Craft. You can verify installation by running php craft plugin/list and install it with php craft plugin/install skills

Base URL Configuration

All API routes require a base URL and API prefix. The standard Craft CMS configuration uses the PRIMARY_SITE_URL environment variable and a configurable API prefix:

  • Environment Variable: Check for PRIMARY_SITE_URL in ENV or .env file
  • If Not Set: Ask the user for the base URL to use
  • API Prefix: Configurable prefix that defaults to /api
    • Check Order:
      1. First check config/skills.php for apiPrefix in the PHP array
      2. If not found, try the default /api
      3. If requests fail, ask the user for the configured API prefix
  • Route Format: {PRIMARY_SITE_URL}/{apiPrefix}/{endpoint}
  • Default Example: https://craft-site.com/api/sections
  • Custom Prefix Example: https://craft-site.com/custom-api/sections

Request/Response Format

All API endpoints:

  • Return JSON: All responses are in JSON format with structured data
  • Accept Header: Include Accept: application/json header in requests to ensure errors are also formatted as JSON for better error handling and debugging
