What security feature does SFCC include to protect APIs?

The security feature that protects APIs in Salesforce Commerce Cloud (SFCC) is OAuth 2.0 authentication. This method provides a robust framework for managing access to APIs by using tokens, which are granted to users or applications after they have successfully authenticated. OAuth 2.0 allows applications to securely obtain access to user resources without sharing sensitive credentials like usernames and passwords.

By utilizing this token-based approach, SFCC ensures that only authorized users and systems can access specific APIs, reducing the overall risk of unauthorized access. In addition, OAuth 2.0 supports features such as scopes, which allow developers to limit access to only the required resources, further enhancing security. This method is widely recognized as a standard for API authentication in web applications, making it a suitable choice for SFCC to implement for securing its API interactions.

Other methods such as basic authentication or API key authentication lack the sophisticated token management offered by OAuth 2.0, which is why they are less preferred for managing access to APIs, especially when security and user experience are important.
