SOAP API Data Format

D.

The SOAP protocol only supports the XML data format.

The only data format permitted with the SOAP (Simple Object Access Protocol) API is XML (eXtensible Markup Language).

SOAP is a messaging protocol that uses XML for exchanging structured and typed information between different systems. XML is used to define the structure of SOAP messages and to represent the data being exchanged.

SOAP is widely used in web services to enable communication between different applications over the internet. It is platform-independent, which means that applications built on different platforms and using different programming languages can communicate with each other using SOAP.

SAML (Security Assertion Markup Language) is an XML-based standard for exchanging authentication and authorization data between parties, typically between an identity provider and a service provider. While SAML can be used with SOAP, it is not the only data format allowed.

XSML is not a valid format and is likely a typo.

HTML (Hypertext Markup Language) is a markup language used to create web pages, but it is not a valid format for exchanging data with SOAP.

Therefore, the correct answer is D. XML.
