Hi. Please HELP.  
Such problem. I do everything according to the video guide. When I send data via postman and process it via getParsedBody (), it returns null.

```php
    use Psr\Http\Message\ResponseInterface as Response;
    use Psr\Http\Message\ServerRequestInterface as Request;
    use Slim\Factory\AppFactory;

    require __DIR__. '/../vendor/autoload.php';

    $app = AppFactory::create();
    $app->get('/', function (Request $request, Response $response) {
        $response->getBody()->write("Hello, World!");

        return $response;
    });

    $app->post('/users', function (Request $request, Response $response, $args) {
        header("Content-Type: application/json;");
        $requestData = $request->getParsedBody();
        print_r($requestData);
        return $response;
    });

```

1. Have you tried to add the BodyParsingMiddleware?

```php
$app->addBodyParsingMiddleware();

```

1. Your (HTTP) client must send the correct request header value `Content-Type: application/json`

![image](https://canada1.discourse-cdn.com/flex030/uploads/slimframework/original/2X/5/59a7f3f2fcf6027da0c8512c1f5d7a2d6c845f10.png)

Read more: [Difference between Accept and Content-Type HTTP headers](https://webmasters.stackexchange.com/a/31231)

> header(“Content-Type: application/json;”);

Better don’t use the vanilla header() function in Slim. To manipulate the response headers use the $response object instead.

> Cannot register two routes…

Make sure, that your routes are not overlapping. Don’t define the same route twice.

Thanks for the answer. But it didn’t help. Can there be more tips?  
I have already spent a lot of time searching for a solution to this problem…

The request `Content-Type` is missing now, it’s **required**.

I should have sent it like this? Through the body and not params? 🙂

Yes, look at your first question 🙂

getParsed **Body** ()

> $requestData = $request-\>getParsedBody();

Maybe I just don’t get your question right. Are you trying to send JSON or form-data to the server?

If JSON set the correct Content-Type Header and switch the mode from form-data to RAW → JSON

Route processes the request. Everything is working out well and now I need to send requests like this?

I was given a test task. I need to make a simple api to output, add, and delete a user saved to a json file

If you want to implement a working RESTful API with JSON then yes 🙂
