DEMO AND EDITOR Run the Bubble demo: https://bubble-xml-feed-kit-demo.bubbleapps.io/version-test
Inspect its inputs, custom states and workflows in the read-only editor: https://bubble.io/page?id=bubble-xml-feed-kit-demo&tab=Design&name=index

QUICK SETUP
1. Add Validate Google Merchant Product Fields to a workflow and map your product data. Read is_valid, missing_required_fields and warnings.
2. Add Build Google Merchant Item XML with the same values. Required fields: product_id, title, description, link, image_link, availability, price_amount, price_currency. Map a decimal amount such as 29.90 (or 29,90), and an actual ISO 4217 currency code such as EUR or USD.
3. Use the returned item_xml only after checking the builder's is_valid and warnings. Malformed basic inputs return empty item_xml.
4. Pass item_xml into Wrap Google Merchant RSS Feed's item_xml_list_or_text input, plus channel_title, channel_link and channel_description. For multiple products, build and collect item fragments first, then join them as one text value. This input is text, not a Bubble list. Use only generated item fragments, not arbitrary or complete XML documents.
5. Use the returned feed_xml and item_count in your app. If publishing an endpoint, use a GET API workflow and Return data from API > Other content-type > application/xml; Text to return = feed_xml. Live endpoints and scheduling depend on your Bubble plan. The plugin does not host a feed for you.

OPTIONAL FIELDS
The builder accepts brand, gtin, mpn, condition (new/used/refurbished), product_type, google_product_category, sale_price_amount and sale_price_currency. Sale currency defaults to price_currency.

VALIDATION SCOPE
Availability inputs such as in stock or available are normalized to in_stock; out of stock and sold out become out_of_stock. Preorder/backorder require an additional availability_date attribute, which this version does not generate, and return is_valid=no. Identifier advice is advisory: missing GTIN/MPN/brand alone does not change is_valid. Currency validation checks the three-letter format, not the full ISO list. GTIN checksums, category/country-specific rules, variants, shipping, tax, landing-page matching and Merchant Center approval are outside this version's validation scope.

PRIVACY AND LIMITS
The plugin executes on Bubble's servers. It makes no external API requests, stores no product data itself and requires no API keys. It does not configure Google Merchant Center, send products to Google, or guarantee product approval. Use synthetic data in the public demo.
