You can send a request to the Bing Application Programming Interface (API) using one of three protocols:

• JavaScript Object Notation (JSON), a data interchange format based on a subset of the JavaScript programming language.
  
  
• Extended Markup Language (XML), a flexible data format derived from Structured Generalized Markup Language (SGML).
  
  
• SOAP (originally an acronym for Simple Object Access Protocol), an XML-based protocol for exchange of information in a decentralized, distributed environment.
  
  

For guidance about which protocol to use, see Choosing the Appropriate Protocol.

Then refer to the appropriate topic for guidance:
