Frequently Asked Questions

How do I authenticate API requests?

The plugin provides two primary methods for authentication:

• API Keys (Recommended for External Tools): From the plugin's "Authentication" settings tab, you can generate dedicated API keys. These are ideal for services like n8n, Pabbly, and Make, as they are independent of user accounts. The key should be sent in the Authorization header as a Bearer token.
• Standard WordPress Authentication: The plugin also supports any standard WordPress authentication method, such as Application Passwords or cookie authentication for logged-in users. This is treated as a fallback if no API key is provided.

What file types can I upload via the media endpoint?

The plugin respects WordPress's allowed file types setting. By default, this includes common image formats (JPEG, PNG, GIF, WebP) and other media files allowed by your WordPress installation.

Can I create custom post types?

Yes! The plugin can create posts of any registered post type, including custom post types created by themes or other plugins.

Is the plugin secure?

Yes, security is a top priority. The plugin includes:

• Comprehensive input validation and sanitization
• File type and size checking
• User permission verification
• Protection against common attacks like SSRF and XSS
