Frequently asked questions
How do I create a new custom API endpoint?
In your WordPress admin panel, go to “Custom API Creator” in the main menu. Click “Add New” to create a new API endpoint. Set your desired endpoint URL, add data sections, choose post types and fields, and set access permissions. Publish your API, and it’s ready to use!
Can I include custom post types in my API?
Yes! Custom API Creator works with any public post type, including custom post types created by other plugins or themes.
How do I restrict access to my API?
When creating or editing an API, you can choose between public access or restricted access. If you select restricted access, you can then specify which user roles are allowed to access the API.
Can I include custom fields in my API response?
The current version focuses on core WordPress fields (title, content, excerpt) and taxonomies. Support for custom fields is planned for a future update
How do I use parameters in my API endpoint?
You can include parameters in your endpoint URL using square brackets, like this: my-api/[parameter]. These parameters can then be used to filter your API results.
Is this plugin compatible with caching plugins?
Yes, Custom API Creator is compatible with most caching plugins. However, for dynamic APIs that change frequently, you may need to configure your caching plugin to exclude your API endpoints.
Can I modify the JSON structure of the API response?
The plugin provides a standardized JSON structure based on your configured sections and fields. For advanced customization of the JSON structure, you may need to use WordPress filters to modify the response.
Is Custom API Creator compatible with WordPress multisite?
Yes, Custom API Creator is fully compatible with WordPress multisite installations.
How can I debug if my API is not working as expected?
Check your endpoint URL, ensure your access settings are correct, and verify that your selected post types have published content. You can also check your server’s error logs for any PHP errors.
Does this plugin support authentication for private APIs?
Custom API Creator uses WordPress’s built-in authentication system. For restricted APIs, users must be logged in and have the appropriate role to access the API.
Can I use this plugin to create APIs for e-commerce data?
While the plugin doesn’t have built-in e-commerce fields, you can use it with e-commerce post types. For deeper integration with specific e-commerce plugins, custom development may be required.
How often is the plugin updated?
We strive to keep Custom API Creator up-to-date with the latest WordPress versions and security best practices. Updates are released as needed for bug fixes, security patches, and new features.
