Im so new using API in my project, so i tried to make an POST request using Guzzle in Laravel, but i really dont know to do it, i've been seraching on the internet how to but i can't find the answer, here's what i've been tried:
$headers = [
'Content-Type' => 'application/json',
'signature' => '73ceef837b9be3cf098eca4a4697bd6a36718b64b0cf407c4324415941ff9780',

"email": "muhammadmaududy4#gmail.com",
"amount": "10000",
"notifyUrl": "https://mywebsite.com",
"expired": "24",
"expiredType": "hours",

$headers, $body);
And i tried to do it on postman and its work perfectly, here's the setting on my postman:

Answer 1

You can use Laravel's Http Facade to deal with requests (easier to test later, if needed):
$headers = [];
$body = [];
$request = Http::send(
method: 'POST',
url: 'https://your.url/',
options: [
'headers' => $headers,
'form_params' => $body,
]
);

Answer 2

$response = Http::withHeaders([
'X-First' => 'foo',
'X-Second' => 'bar'
])->post('http://example.com/users', [
'name' => 'Taylor',
]);
I show a example code on top. I provide your code below.
$response = Http::withHeaders ([
'Content-Type' => 'application/json',
'signature' => '73ceef837b9be3cf098eca4a4697bd6a36718b64b0cf407c4324415941ff9780',
'va' => '0000002298436631',
'timestamp', '20191209155701'
])->post('https://sandbox.ipaymu.com/api/v2/payment/direct',[
"name": "Dudy",
"phone": "082298436631",
"email": "muhammadmaududy4#gmail.com",
"amount": "10000",
"notifyUrl": "https://mywebsite.com",
"expired": "24",
"expiredType": "hours",
"comments": "Catatan",
"referenceId": "1",
"paymentMethod": "qris",
"paymentChannel": "qris"
]);

Answer 3

Try this
$client = new \GuzzleHttp\Client();
$response = $client->post(
'https://sandbox.ipaymu.com/api/v2/payment/direct',
[
'form_params' => [
"name" => "Dudy",
"phone" => "082298436631",
"email" => "muhammadmaududy4#gmail.com",
"amount" => "10000",
"notifyUrl" => "https://mywebsite.com",
"expired" => "24",
"expiredType" => "hours",
"comments" => "Catatan",
"referenceId" => "1",
"paymentMethod" => "qris",
"paymentChannel" => "qris"
]
],
[
'headers' => [
'Content-Type' => 'application/json',
'signature' => '73ceef837b9be3cf098eca4a4697bd6a36718b64b0cf407c4324415941ff9780',
'va' => '0000002298436631',
'timestamp', '20191209155701'
]
]
);
dd($response) //response data
