XML Feed Product Integration

Sizebay supports product integration via XML feeds based on the Google Merchant Center standard. This approach simplifies implementation while ensuring compatibility with e-commerce best practices.

1. Requirements

The XML feed should be segmented by each unique combination of country, language, and currency to ensure accurate localization.

Parameter	Description	Required for Separate Feed?
target_country	Country where the product is sold	✅
content_language	Language used for product content	✅
currency	Currency in which the product is priced	✅

Rule of thumb: You must provide one XML feed per unique combination of target_country + content_language + currency

4. Feed Update Frequency

Sizebay fetches your XML feed once per day at 05:00 AM (GMT+0).

• If the product does not exist, it will be automatically added to our system.

• If the product already exists, it will be updated based on changes in:

• title

• price

• sale_price

• sale_price_effective_date

• availability

Make sure your XML is accessible and up-to-date before the scheduled fetch time.
