Update operation

There can be two types of update operations:

• Update some attributes of a particular record
• Replace that particular record completely with a new one

Only thing that change to perform these two operations: HTTP method.

With the Update operation, to update some of attributes of the resource use:

HTTP method: PATCH

While to replace the whole resource use:

HTTP method: PUT

The URI and the parameters will remain the same:

URI: /{resource}/{resource_id}

Parameters: There can be multiple parameters in a query string. Initially, people try to pass these parameters in the body but actually, the PATCH and PUT parameters are passed using a query string.

Result: This should update or replace the resource based on the HTTP method.

Here, resource_id will be the ID of the resource which can be found from the List operation's result. Again, practically using PATCH or PUT will not make any difference but based on REST standards PATCH should be used for updating the different attributes of a record while PUT should be used for replacing the whole resource.
