Connect and Transform External Data Seamlessly

Connect and Transform External Data Seamlessly is an intermediate course for developers and data professionals who need to build reliable pipelines from external data sources. In a connected world, simply accessing an API isn't enough; you must do it securely and be able to use the data you retrieve. This course provides the essential skills to master both sides of that equation: secure connection and effective transformation. Drawing on real-world best practices for REST API security and data engineering, you will get hands-on with the OAuth 2.0 protocol. You will learn how to implement secure authentication flows to manage access tokens and protect sensitive credentials. Next, you will dive into the practical challenge of data transformation, learning to parse and flatten complex, nested JSON into a clean, relational format ready for analysis in databases like BigQuery or PostgreSQL. By the end of this course, you will be able to confidently and securely integrate third-party data into your applications and analytics workflows.
