## Generic product XML

The most common shape: a root element containing one child element per product, with fields as child elements or attributes. Element names vary by supplier (`product`, `item`, `urun`, `artikel`) and are detected from the content, not the name.

## Google Merchant Center feeds

RSS 2.0 or Atom feeds with fields in the `g:` namespace (`g:id`, `g:title`, `g:price`, `g:sale_price`, `g:availability`, `g:image_link`, `g:item_group_id` and so on). Items sharing an `item_group_id` become variants of one product. See [Google Merchant feeds](/features/google-merchant-feed).

## RSS and Atom catalogues

Plain RSS or Atom feeds where each item carries product data in custom or Dublin Core elements. Prices and stock are taken from any element that looks like a price or quantity.

## Variant shapes

- **Nested**: variants listed under the product element.
- **Flat**: every variant is its own product element with a parent or group code.
- **Attribute-based**: size or colour given as attributes rather than elements.

## Multi-file catalogues

Some suppliers split data across files: one XML with product details, another with stock or prices, sometimes a third with images. These are configured by support as a composite feed and behave like a single feed in the app.

## Encodings and namespaces

UTF-8, ISO-8859-1 and Windows-1254 declared in the prolog are handled. Namespaced elements are matched by local name, so `g:price` and `price` are treated alike where appropriate.

## FAQ

### My feed has a custom structure. Will it work?

Probably. The app scores the feed against known layouts and picks the closest. When nothing fits well enough, our team adds a profile for your feed, usually within a business day.

### Do you support JSON or CSV feeds?

No. The app reads XML only. Ask your supplier whether they also publish an XML or Google Shopping feed; most do.
