How do I find help on synching my product database with ebay and other online sales channels?

Hi,

When you say sync, which direction do you mean?

Your database into ebay's database? Or the other way round?

I know that ebay has web services API to do that:

From your database to ebay:

http://developer.ebay.com/products/trading/

From their to yours:

http://developer.ebay.com/products/open-ebay-apps/

Also, amazon has a similar API:

Let me know if you are looking for any more specific information.
