What is the Access-Control-Allow-Methods header?
The Access-Control-Allow-Methods HTTP header is used to transmit metadata between a client and server as part of HTTP requests or responses.
HTTP headers define how content should be interpreted, cached, authenticated, secured, or processed by browsers and APIs.
Direction
This header may appear in both HTTP requests and responses.
Syntax
Access-Control-Allow-Methods: GET, POST, PUT
Example
Access-Control-Allow-Methods: GET, POST, PUT, DELETE
Common use cases
- CORS preflight responses

Common mistakes

- Assuming the header automatically changes server behaviour
