• Repeated calls to the server produce the same result
• Making multiple calls should result in the same mutation as making a single request
• Response from the server might not be the same (the resource changed between requests)
• PUT and DELETE

Difference between PUT and POST

• PUT is idempotent whereas POST is not
• PUT completely overwrites a resource at a particular KNOWN URL
• POST creates a resource at an unspecified URL
• Rule of thumb if to use PUT to update a resource and POST to create a resource

Difference beetween PUT and PATCH

• PATCH is not idempotent
• PATCH can update part of resources
