CRUD Operations In SharePoint REST API Using jQuery AJAX

In this article, I have explained how to perform create, read, update, and delete operations on SharePoint list items using HTTP requests.

HTTP Request Use
GET This method helps to fetch the information fromSharepoint list
POST This method helps to create or update the list items in sharepoint listPUT: Required all the object properties to update the resourcesMerge: Optional to required all the object properties to update the resources
PUT/MERGE This method helps to update the existing object using X-HTTP method
DELETE This method helps to delete the object from sharepoint list

Open sharepoint site,

Create a list name “Employee” to play Create, Read, Update, Delete Operations using HTTP RequestsP
