Catalog

Public endpoints. No API token is required. Resource-group visibility is shared with the catalog snippet. ProductCatalogService builds the JSON, not the snippet's pdoFetch.

Product

Method	Path	Purpose
GET	/product/get/{id}	Product by ID
GET	/product/get	Resolve: alias or uri parameter, optional context
GET	/product/list	List / PLP
GET	/product/filters	Facets
GET	/product/{id}/images	Gallery

Query parameters for get and resolve: context, include_images (0|1, default 0), include_seo (default 1).

Main query parameters for list:

Parameter	Meaning
parent / category	Category ID (kept for backward compatibility; ignored if parents is set)
parents	CSV or array of category IDs. OR condition, and a product matches both by its primary category and by additional links (msCategoryMember)
nested	0|1. Expands the tree when parents is set
price_min, price_max	Price range
in_stock, stock_min	Stock
vendor_id, new, popular, favorite	Flags / vendor
options	Options JSON
limit, offset / page	Pagination. limit defaults to 20, maximum 100
sort, dir, query, context	Sort and search
include_options, include_content, include_images	Embeds (include_images default 0, at most 10 files per product)
include_seo	SEO block. The default is 0 on list and 1 on get

list response:

{
  "success": true,
  "message": null,
  "data": {
    "items": [
      { "id": 12, "pagetitle": "Mug" }
    ],
    "total": 1,
    "limit": 20,
    "offset": 0
  }
}

filters takes the same filters as list, plus keys, include_price (default 1), and include_vendors (default 0).

GET /product/{id}/images and the product card return up to 50 gallery files.

Category

Method	Path	Purpose
GET	/category/get/{id}	Category by ID
GET	/category/get	Resolve by alias / uri
GET	/category/list	List
GET	/category/tree	Tree

get parameters: context, include_hidden, include_content, include_breadcrumbs, include_children, include_seo (default 1).

list parameters: parent, limit, offset or page, sort, dir, context, include_hidden, include_content, include_seo (default 0).

tree parameters: parent, depth, context, include_hidden, sort, dir, include_seo (default 0).

With include_children=1 the nested categories in children also receive seo, unless include_seo is off.

SEO block

The block arrives in seo when include_seo is on. Assembly order:

1. Base values from the resource fields.
2. canonical.
3. Overrides from the TV map.
4. The msOnGetPublicSeo event.

Key	Source
title, description	Resource fields, overridden by the TV map where present
canonical	Built with MODX makeUrl. With friendly URLs off it comes out as index.php?id=N, so the link keeps working
robots	index,follow or noindex,nofollow. See searchable
og.*	From the TV map: og.title, og.description, og.image, og.type

The TV map is the ms3_public_seo_tv_map system setting: JSON that maps an SEO key to a TV name. Allowed keys are title, description, canonical, robots, og.title, og.description, og.image, og.type. Invalid JSON is ignored. The setting is empty by default: without it the SEO block is built from the resource fields alone.

The searchable field

Product and category responses carry searchable (the "Searchable" flag of the MODX resource). When it is off, robots in the SEO block becomes noindex,nofollow. Nothing else depends on it: the entry itself stays in the API output.

Resource group ACL

The filter is on only when both settings are true: MODX access_resource_group_enabled (on by default) and ms3_web_catalog_respect_resource_groups (the installer writes true).

A guest is matched against a permission that is not tied to a user. A customer also receives groups from msCustomerGroup through MODX user-group ACL.

Membership is "at least one": the document stays visible when any of its groups grants access, even if another group is closed.

Turn off ms3_web_catalog_respect_resource_groups to serve products without resource-group checks.
