# AS2

Couchdrop supports AS2 for secure, business-to-business file exchange with partners and trading networks. Use Couchdrop as an inbound AS2 endpoint, connect to external AS2 partners for outbound transfers, and manage AS2 alongside your other transfer methods and storage connections.

You can use Couchdrop AS2 to:

* Receive files from trading partners over AS2
* Send files to external AS2 partners
* Modernize AS2 file exchange without managing traditional AS2 infrastructure
