Fetch API

The Fetch API provides an interface for executing network calls programmatically. You can use fetch() to programmatically configure and execute a REST API.

Examples

GET request

const questions = await fetch("https://opentdb.com/api.php?amount=10")
return questions.json()

POST request

fetch("https://63772c9a5c477765121615ba.mockapi.io/users", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    name: "Alex",
    email: "alex@appsmith.com",
  }),
}).then((response) => {
    console.log("Success:", response.json());
}).catch((error) => {
    console.error("Error:", error);
});

File upload

const formData = new FormData();
formData.append("file", FilePicker1.files[0]);
        
let response = await fetch('https://httpbin.org/post', {
    method: 'POST',
    body: formData
});
