Using SSL for data transmission is essential for maintaining the security of single sign-on (SSO) transactions, especially when using session IDs (SID) and endpoint URLs. SSL (Secure Socket Layer) provides a secure channel over the internet, ensuring that the data sent between the client and the server is encrypted. This means that any information, including the SID, cannot be easily intercepted or tampered with by malicious actors during the transmission process.

When SSO transactions occur, the SID must be transmitted securely to validate the user's identity across different applications or services. By using SSL, organizations can safeguard this sensitive information from potential exploits like man-in-the-middle attacks, where an attacker could intercept communication to gain unauthorized access to user sessions or sensitive data.

While encrypting the SID and never transmitting it to third-party sites are important considerations, they are not as directly related to the immediate protection during data transmission as the implementation of SSL. Validating the SID at the endpoint does add a layer of security, but without a secure transmission method in place, the SID could still be exposed to threats. Thus, securing data transmission through SSL stands as a primary defense mechanism in protecting single sign-on transactions.
