POST Request to external API resulted in a `500 Internal Server Error`-CodePudding

so i have a task that need to do POST to an external API with {{url}}/link-ec/submit (this is for example)

and i did with form request input, and end up with 500 Internal Server Error

i'm using laravel controller for submitting this form

this is my controller

$dataSubmit = [
                "customerName"          =>  $request->input('customerName'),
                "mobilePhone"           =>  $request->input('mobilePhone'),
                "nik"                   =>  $request->input('nik'),
                "birthPlace"            =>  $request->input('birthPlace'),
                "birthDate"             =>  $request->input('birthDate')
];



$clientSubmit = new \GuzzleHttp\Client(['headers' =>             
            'Accept' => 'application/json',
            'Content-Type' => 'application/json',
            'Authorization' => 'Bearer token']);

$responseSubmit = $clientSubmit->request(
            'POST',
            'url/link-ec/submit',
            ['json' => $dataSubmit]

        );
        $responseSubmit = json_decode($responseSubmit->getBody(), true);

        return $responseSubmit;

in case you guys need the route and form to know the problem:

Route::get('/post-link', 'IntegrationController@submit');
<form class="form form-fifastra financing-form" method="GET" id="form-apply"
                                action="{{ url('post-fifada') }}">
                                @csrf
</form>

this is the error

CodePudding user response：

The problem is that the API cannot deserialize the request body. Try to json encode the body before sending it, because the API expect a json in the body.

$responseSubmit = $clientSubmit->request(
        'POST',
        'url/link-ec/submit',
        ['json' => json_encode($dataSubmit)]

    );
