# Product Feeds

> How product feeds work with Molin AI.

Product feeds allow Molin to automatically sync your product catalog and keep your AI assistant up to date with the latest product information, pricing, and availability.

## Supported feed formats

Molin supports the following feed formats:

* [Google Shopping feed](/home/platforms/google-shopping-feed) (XML/CSV)
* [Árukereső/Compari feed](/home/platforms/arukereso-compari-feed) (XML)
* [Prefixbox feed](/home/platforms/prefixbox-feed) (JSON)
* Heureka XML
* JSON (schema.org format)

## Feed authentication

You can protect your feed with one of the following authentication methods:

* **Basic Auth**: standard HTTP Basic Authentication with username and password
* **Bearer token**: OAuth-style Bearer token authentication
* **Custom header**: any custom HTTP header for authentication

Please reach out to our customer support team to set up feed authentication.

## Feed requirements

Your product feed should include at minimum:

* Link
* Price
* Title
* Description

We strongly recommend including additional attributes like:

* Availability
* Images

## Product field limits

Molin enforces character limits on product data to ensure optimal performance and consistent AI responses. Fields exceeding these limits are automatically truncated.

## Feed updates

Molin automatically checks your feed for updates regularly to keep your product information current. The frequency depends on your plan.

## Platforms supported without a custom feed

You don't need a custom feed if you connected Molin to one of the supported e-commerce platforms:

* [Shopify](/home/platforms/shopify)
* [ShopRenter](/home/platforms/shoprenter)
* [UNAS](/home/platforms/unas)
* [WooCommerce](/home/platforms/woocommerce)

## Troubleshooting

If Molin cannot access your feed, check:

* The feed URL is publicly accessible from [our static IPs](/home/general/static-ips)
* Your security solution is not blocking our requests (see [Feed allowlisting](/home/general/feed-allowlisting))
* The feed format is valid and follows the expected schema
* Authentication credentials are correct (if using feed authentication)
