Paypal / field missing when I try to capture a multiseller payment - php

Question

Here is the response, I don't urdestand what is the problem.
{
"name": "INVALID_REQUEST",
"message": "Request is not well-formed, syntactically incorrect, or violates schema.",
"debug_id": "5939e86ea6f6e",
"details": [
{
"field": "/",
"location": "body",
"issue": "MALFORMED_REQUEST_JSON",
"description": "The request JSON is not well formed."
}
],
"links": [
{
"href": "https://developer.paypal.com/docs/api/orders/v2/#error-MALFORMED_REQUEST_JSON",
"rel": "information_link",
"encType": "application/json"
}
]
}
And the code, what calls the capture endpoint:
$headerForBasicAuth = $this->paypalModel->getBasicAuthHeader();
$http = Http::withHeaders([
'Authorization' => 'Basic '.$headerForBasicAuth,
'Content-Type' => 'application/json'
]);
$response = $http->post($this->paypalModel->getBasePath().'/v2/checkout/orders/'.$request->orderID.'/capture')->body();
If needed, there is the code, how I create the order:
$headerForBasicAuth = $this->paypalModel->getBasicAuthHeader();
$http = Http::withHeaders([
'Authorization' => 'Basic '.$headerForBasicAuth,
'Content-Type' => 'application/json'
]);
$body = [
'intent' => "CAPTURE",
'purchase_units' => [
[
'payee' => [
"merchant_id" => "V2B4REMFCWFE6"
],
'amount' => [
'currency_code' => 'USD',
//'value' => $data['price']
'value' => '15'
],
'payment_instruction' => [
'disbursement_mode' => 'INSTANT',
'platform_fees' => [
[
'amount' => [
'currency_code' => 'USD',
'value' => '5'
]
]
]
]
]
],
'application_context' => [
'cancel_url' => 'http://laravel-paypal-example.test',
'return_url' => 'http://laravel-paypal-example.test',
'shipping_preference' => 'NO_SHIPPING'
]
];
$response = $http->post($this->paypalModel->getBasePath().'/v2/checkout/orders', $body)->body();
I'm using platform fee, but in admin menu, I can't enable the platform fees checkbox, every time give an error: "Your settings weren't saved. Please try again later."
The orderID is okay, I checked many times. So, when I create an order, I can accept the payment in the PayPal checkout, but when the transaction is approved, I can't capture it with orderID.

Somehow there is a request body in what you are posting to the /capture endpoint. From looking at your code I can't tell how/why a body is being added, but it is in fact being added, and whatever is added is not valid JSON, and hence the request is rejected.
