Answer: Use external functions.

The correct answer is B (External Functions) because they are specifically designed to integrate third-party SaaS services with Snowflake. External Functions allow Snowflake to securely call external HTTP-based APIs (like Amazon Textract, Google Document AI, or Azure Computer Vision) without moving data out of Snowflake's environment. This aligns with Snowflake's best practices for processing unstructured data using external services. Option D (API Gateway) is incorrect because while API Gateway can be used as part of the infrastructure for External Functions, it's not the primary method Snowflake users employ to access third-party services - External Functions are the Snowflake-native solution. Options A (Internal Functions) and C (Process Functions) are not valid Snowflake concepts for this use case.
