S2S generally refers to Server-to-Server communication. It describes the process of transferring data directly between two servers without the involvement of a client (like a web browser or mobile app) as an intermediary. This is commonly used for tasks such as verifying transactions (e.g., ad conversions), data synchronization between systems, secure API integrations, and other back-end processes where direct, reliable communication is needed.
