Enhances your store’s REST API by adding powerful, flexible endpoints. 
Stay tuned more are coming!
Add or Remove a Single Category
Easily append or remove one category at a time—by numeric ID or human-friendly slug—using simple POST/PUT/PATCH or DELETE requests to 
 /wp-json/wc/v3/products/{product_id}/categories/{identifier}
Batch Manage Multiple Categories
In a single call, add or remove multiple categories at once via JSON payloads to 
 /wp-json/wc/v3/products/{product_id}/categories 
Supply an array of IDs or slugs under the “categories” key to update your product’s category list in bulk.
Automatic Slug Resolution 
Pass slugs like “summer-collection” and the plugin will resolve them to the correct WooCommerce term IDs on the fly—no extra lookups required.
Non-Destructive Updates 
Neither endpoint touches other product data. Categories are merged or pruned transparently without overwriting prices, stock, attributes, or any other fields.
Built-In Validation & Security
Sanitization of all inputs (IDs and slugs) to guard against bad data.
Permission checks ensure only users with the edit_products capability (Shop Manager, Admin) can modify categories.
Clear, standardized error codes (w3s_api_extension_invalid_product and w3s_api_extension_invalid_product_category) for consistent API responses.
W3S API Extension for WooCommerce installs alongside the core WooCommerce REST API, requires no additional configuration, and works out of the box.
