# When to prefer PUT over POST HTTP method?
|
||
|
|
|
||
|
|
`PUT` should be idempotent. This means that it's harmless to call a `PUT` request many times. On the contrary, calling `POST` requests repeatedly might change data on the server again.
|
||
|
|
|
||
|
|
A way to see it is:
|
||
|
|
|
||
|
|
* `PUT` = SQL `UPDATE`
|
||
|
|
* `POST` = SQL `INSERT`
