How do I make a POST call in React Native?

css’; function callApi() { alert(‘Button was pressed! ‘); } function App() { return ( <div className=”App”> <header className=”App-header”> <button onClick={callApi}>Call API</button> </header> </div> ); } export default App; This will give us a button that when pressed will show an alert saying Button was pressed! .

POST request using fetch API: To do a POST request we need to specify additional parameters with the request such as method, headers, etc . In this example, we’ll do a POST request on the same JSONPlaceholder and add a post in the posts. It’ll then return the same post content with an ID.

By design, the POST request method requests that a web server accept the data enclosed in the body of the request message, most likely for storing it . It is often used when uploading a file or when submitting a completed web form. In contrast, the HTTP GET request method retrieves information from the server.
