PUT

The PUT method replaces all current representations of the target resource with the request payload.

Usage

PUT is idempotent. Sending exactly the same PUT request multiple times will always result in the same state on the server. If the resource does not exist, it may create it.

Bun / Node.js

const response = await fetch('https://api.example.com/data/123', {
    method: 'PUT',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ name: 'updated name' })
});
