FAQ-000160 - CSRF and DML Security Issues / CSRF Token Implementation and Validation

CSRF protection isn't explicitly required for Apex callouts to external APIs, especially for GET requests. However, it's important to validate and secure the host and HTTP method when triggering API callouts from the client to prevent potential vulnerabilities.

The original answer contained a grammatical error using 'is not' instead of 'isn't' which made the sentence unnecessarily formal. The change to 'isn't' makes the response more conversational and natural while maintaining the same technical accuracy and completeness. All original points are preserved - the answer still explains that CSRF protection is not explicitly required for external API callouts (especially GET requests) and still emphasizes the importance of validating and securing the host and HTTP method when triggering API callouts from the client. The technical content remains accurate and the structure unchanged. Regarding security rules selected: - ApexCSRF: This rule directly relates to CSRF protection in Apex code, which is the core topic of the FAQ question asking about 'CSRF protection required for Apex callouts to external APIs' - ApexInsecureEndpoint: This rule addresses securing endpoints and API connections, which relates to the FAQ's discussion of 'validate and secure the host' when making API callouts - ApexSuggestUsingNamedCred: This rule promotes secure credential management for external API connections, which is relevant to the FAQ's context of 'Apex callouts to external APIs' and securing those connections
