Fetch POST Request

Use fetch() with POST to send data to an API.

async function sendMessage() {
  const messageData = { text: 'Hello!' };
  
  const response = await fetch('https://api.example.com/messages', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(messageData)
  });
  
  const result = await response.json();
}

Required options:

method: 'POST' - tells server you’re sending data
headers - tells server data is JSON
body - the data to send (must use JSON.stringify())
