# HTTP Methods & CRUD — REST API Design

Source: https://www.geekswithgeeks.com/en/restapi/api-http-methods

> Mapping create, read, update, delete onto HTTP verbs.

## The core five

**GET** reads a resource. **POST** creates a new one (or triggers an action). **PUT** replaces a resource entirely. **PATCH** partially updates it. **DELETE** removes it. Picking the right verb communicates intent before anyone reads a body.

## CRUD to HTTP

The classic mapping onto a single resource collection.

```text
POST   /orders          -> Create
GET    /orders          -> Read (list)
GET    /orders/482      -> Read (one)
PUT    /orders/482      -> Update (replace)
PATCH  /orders/482      -> Update (partial)
DELETE /orders/482      -> Delete
```

## Safe vs unsafe

GET and HEAD are **safe** — they must not change server state, so browsers, proxies, and crawlers can call them freely. Never do a delete or a write behind a GET.
