Deprecated

10. What is SOAP?
Created by Microsoft in 1998 / W3C Standard
Protocol Agnostic / Common to use HTTP
RPC Message Pattern (Request/Response)
XML Schema used for Message Structures

11. SharePoint Web Service Addresses
Web Service Web Service Address
Search http://<site>/_vti_bin/search.asmx
User Profiles http://<site>/_vti_bin/userprofileservice.asmx
Sites http://<site>/_vti_bin/sites.asmx
Lists http://<site>/_vti_bin/lists.asmx
Permissions http://<site>/_vti_bin/permissions.asmx
Copy http://<site>/_vti_bin/copy.asmx
31 Public Web Services (25+6) in SharePoint

12. SOAP Request Message Format
SOAP Envelope
SOAP Body
Method and
Parameters

13. SOAP Considerations
• All Versions of SharePoint
• Ubiquitous
• Protocol Agnostic
• Language Agnostic
• Access to Enterprise Services
• Designed to work with Proxy
• Not JavaScript Friendly
• Verbose Xml Data
• No Anonymous

14. What is the CSOM?
Proprietary Microsoft SharePoint Client API
.NET / Silverlight / WP7 / ECMAScript
Mimics Server-side Object Model
Proprietary Message Transfer Format

15. CSOM Architecture

16. CSOM (.NET)
Create a Context
Load the Context
Execute Query
Access Properties

17. CSOM Considerations
• Efficient for Batch Operations
• Familiar for SharePoint
Developers
• Supports LINQ Queries
• Works with Anonymous
• Less Efficient for Simple
Operations
• Unfamiliar to Web Developers
• Limited # of Client Runtimes
• Microsoft Proprietary

18. What is REST?
Representational State Transfer
Web Addressable Resources / Hyperlink-able
Maps CRUD operations with HTTP Verbs
Commonly uses JSON for Data Messages

19. Anatomy of a REST Call
Request URLHTTP Method
HTTP Body with
Encoded DataHeaders

20. HTTP Status Codes
Status Code Description
200 OK The server successfully processed the request.
400 Bad Request The server didn't understand the request.
401 Unauthorized The request requires authentication.
404 Not Found The server can't find the requested page.
500 Internal Server Error The server encountered an error.
Calling a web service
requires checking the
status code to validate
success

21. Data Encoding - ATOMPUB

22. Data Encoding - JSON

23. REST Considerations
• Efficient for simple operations
• Familiar to Web Developers
• HTTP and open standards
• Very JavaScript Friendly
• Limited support for Anonymous
• Complex for batch operations
• Unfamiliar to SharePoint
Developers
• Requires knowledge of HTTP
protocol and programming

24. Anatomy of a REST
Call
 Using the List Data Service
 Using the Client REST API
 Data Encoding
