PUT: Updates a resource at a specific URI. Idempotent—sending the same request multiple times results in the same outcome.eg-PUT api/users/123 {"name": "Jane Doe","email": "[email protected]" } here we are updating user with id =123.POST: Creates a new resource, usually without specifying the URI (the server decides). Non-idempotent—multiple requests can create multiple resources. eg-> POST api/users {"name": "Jane Doe","email": "[email protected]" } Here we will create a new user (resource ) in server and return the status 201.
