Have you dealt with API (SOAP)?

Yes, I have experience working with SOAP API. SOAP (Simple Object Access Protocol) is a message exchange protocol based on XML, often used for communication between distributed systems.

As a systems analyst, I analyzed WSDL files (Web Services Description Language), which describe available methods, data types, and message structures of SOAP services. This helped in correctly forming requests and processing responses.

Examples of using SOAP API:

• Retrieving customer data via the getCustomerInfo method
• Handling errors returned in SOAP Faults

For testing and analyzing SOAP services, I often used tools like SoapUI, which allow visually creating requests and viewing responses.

Important points when working with SOAP API:

• Clear understanding of the structure of XML messages
• Handling SOAP headers (e.g., for authentication)
• Considering protocol versions and security standards (WS-Security)
