Headers & Authentication

HTTP headers send extra information with requests. The Content-Type header tells the server you are sending JSON. The Authorization header sends a token to prove who you are.

APIS
// Sending headers with fetch
fetch("https://api.example.com/users", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "Authorization": "Bearer your-token-here"
  },
  body: JSON.stringify({ name: "Ali" })
});
