Google Merchant Shopping Feeds for PrestaShop - Boost Your Ads (1.6-1.7)

Export your PrestaShop catalogue to Google Merchant Center the right way. Shopping Feed for Google Merchant builds a clean, Google-compliant RSS/XML product feed straight from your shop, ready to submit in Merchant Center for Google Shopping and Performance Max campaigns.

From version 2.0 the module is fully multi-feed: create any number of feeds, each with its own name, status, settings and generation URL, all managed from a single feed-list screen. Every feed carries its own product filter, its own field mapping and its own language/currency variant, so a single PrestaShop install can drive separate feeds for different markets, currencies or campaigns.

The feed maps PrestaShop products to Google attributes — id, title, description, link, image_link, price, brand, condition, availability, google_product_category, gtin, mpn, item_group_id and custom_label_0 through custom_label_4 — and emits identifier_exists=no automatically when a product has no usable GTIN or brand+MPN, eliminating Merchant Center "missing identifier" warnings. Product variants are exported separately, each with its own link, image and item_group_id grouping; item_group_id is emitted only for real attribute combinations, never on simple products.

Large catalogues are handled with a streamed, memory-safe generator: the feed is written to a cached XML file in batches of 500 products with a flush between batches, so the whole feed is never assembled in memory. Feeds can be regenerated on demand (&refresh=1), served from cache for speed, output as gzip, and generated from cron for hands-off scheduled refreshes. Multistore and the full PrestaShop multilanguage / multicurrency model are supported.

Supported versions:

PrestaShop 1.6 through 8.x and 9.x (ps_versions_compliancy min 1.6 → current).

Emitted Attributes Schema: g:id, g:title, g:description, g:link, g:image_link, g:price, g:brand, g:condition, g:availability, g:google_product_category, g:gtin, g:mpn, g:item_group_id, g:identifier_exists, g:custom_label_0..4

Custom Labels Mapping: bind identifiers custom_label_0..4 cleanly onto chosen attribute groups or store characteristics.

Streaming Engine Parameters: writes cached XML outputs in stable 500-product batches; features optional gzip compression loops; manages automation requests using cron.php command lines.

Data Integrity Design: feed properties are isolated systematically as JSON; idempotent installation routines migrate legacy single-feed profiles safely without data loss.

Dynamic Feed URL Base:

index.php?fc=module&module=googlemerchantpremium&controller=generation&id_feed=N&shop_id=S

Optional parameters: &id_lang=L, &id_currency=C, &refresh=1

Cron Script Structure:

cron.php --shop_id=S --id_feed=N [--gzip]
