SOAP and REST API Course

Uplatz provides this comprehensive course on SOAP and REST API. It is a self-paced course with recorded video lectures. You will be awarded Course Completion Certificate at the end of the course.

SOAP is a protocol used for exchanging structured information between systems over a network. It relies on XML to format messages and typically uses HTTP or SMTP for communication.

• A client sends a SOAP request in XML format to a SOAP server.

• The server processes the request and sends back an XML-formatted response.

• Communication is done using a WSDL (Web Services Description Language) file, which defines the service operations and message structure.

• Protocol-based (strict standards to follow)

• Uses only XML for message formatting

• Supports WS-Security for encryption and authentication

• Built-in error handling through fault elements

• Supports stateful and stateless operations

• Language and platform-independent

• Requires more bandwidth due to XML overhead

REST is an architectural style that uses standard HTTP methods to interact with resources (data) via URLs. It's lightweight, flexible, and commonly used in web services.

• A client makes an HTTP request (GET, POST, PUT, DELETE) to a RESTful API endpoint (a URL).

• The server processes the request and returns a response, typically in JSON or XML format.

• Each URL represents a resource, and HTTP methods define the action on that resource.

• Stateless: Each request is independent; no session info stored on the server

• Uses standard HTTP methods (GET, POST, PUT, DELETE)

• Supports multiple data formats, commonly JSON

• Lightweight and fast (less overhead than SOAP)

• Scalable and ideal for web and mobile applications

• Easy to integrate with modern frontend frameworks
