Sending Simple Apex Post Request

Question

I have narrowed down why my apex post request is not sending to an external API. For some reason the JSON data that I serialize and send is wrong but everything works when I test it using Postman.

    Http http = new Http();
    HttpRequest req = new HttpRequest();
    req.setEndpoint('apilink.com');
    req.setMethod('POST');
    req.setHeader('Content-Type', 'application');
    req.setHeader('Authorization', 'token'); 

    String body = '{"gift_id": "12345", "recipients": [{"email": 
    "[email protected]", "fist_name": "Test", "last_name": "test", 
    "message": "Testing post", "type": "email"}]}';
    req.setBody(JSON.serialize(body));
    HttpResponse response = http.send(req);

I get error code 400 which means bad data is being sent.

Any help would be awesome.

Figured it out (Noob mistake).... Did not need to serialize the JSON data. Thanks everyone.
