REST (SharePoint)

SharePoint Representational State Transfer (REST) service.

REST (Representational State Transfer) is an architectural style that allows you to interact with SharePoint data using standard HTTP requests. SharePoint provides a RESTful web service that enables developers to access and manipulate SharePoint resources such as lists, items, and libraries in a straightforward and flexible manner.

• Standard HTTP Methods: Supports standard HTTP methods like GET, POST, PUT, and DELETE to perform CRUD operations.
• JSON Format: Data is exchanged in JSON format, making it easy to work with in JavaScript and other programming languages.
• OData Protocol: Supports OData (Open Data Protocol), allowing for rich querying capabilities, including filtering, sorting, and pagination.
• Cross-Domain Requests: Can be accessed from client-side code in browser scenarios using CORS (Cross-Origin Resource Sharing).

• Retrieving list items and document libraries.
• Creating new list items or libraries.
• Updating existing items.
• Deleting items from lists or libraries.
• Executing complex queries and fetching related data.

To retrieve items from a SharePoint list using the REST API, you would perform a GET request to the following endpoint:

GET /_api/web/lists/getbytitle('ListName')/items

This will return a JSON array of items in the specified list.

Accessing the REST API in SharePoint typically requires authentication. Depending on the environment (on-premises or SharePoint Online), you may use:

• OAuth tokens (for SharePoint Online)
• NTLM or Kerberos (for on-premises SharePoint)
