SOAP vs. REST: What's the difference and when should you use each?

The text explores the debate between SOAP and REST, two key API technologies used for enabling communication between different software applications. SOAP, a protocol developed in the late 1990s, is known for its standardized structure using XML, making it suitable for environments requiring strict security and transaction reliability, such as financial services and healthcare. REST, on the other hand, is an architectural style that emerged in 2000, emphasizing simplicity and scalability with its use of standard web technologies like HTTP and JSON. REST is generally preferred for public APIs and mobile apps due to its flexibility and lightweight nature, although SOAP's formal structure is beneficial for enterprise settings requiring rigorous standards. The text also introduces GraphQL, a newer API approach by Facebook that allows more precise data queries, offering advantages in handling multiple data sources but also introducing server-side complexity. Additionally, the text mentions Zapier, a tool that simplifies API interactions by automating tasks without requiring code, highlighting its role in easing the integration of various applications.
