Technically, API stands for Application Programming Interface. From the business perspective, it is the layer to scale up and communicates with a different system to turn IT/Data to business benefits. So, if we consider the Data is the new 21st century’s oil, the Pipeline is the Data Pipeline, and the API is the Faucet. Therefore, API security is important for companies and organizations. API security affect application and data security, data privacy. This book help to secure your APIs. it includes best practices to secure APIs.
