can i use stripe checkout with destination charges? - laravel

Question

I'm wondering if there is any way to charge some kind of fee on transactions using the new Stripe Checkout system. In this particular instance I am using Laravel 8 with Livewire. In my component I have a function tied to a button called setStripeSession.
\Stripe\Stripe::setApiKey(env('STRIPE_SECRET'));
$session = \Stripe\Checkout\Session::create([
'payment_method_types' => ['card'],
'line_items' => [[
'price_data' => [
'currency' => 'usd',
'product_data' => [
'name' => 'Custom Media',
],
'unit_amount' => $this->toPennies($price),
],
'quantity' => 1,
]],
'mode' => 'payment',
'success_url' => 'http://e68ec3e6b8b2.ngrok.io/',
'cancel_url' => 'http://e68ec3e6b8b2.ngrok.io/',
],['stripe_account_id'=>$this->stripe_account_id]);
$this->stripe_session_id = $session->id;
Message::where('id',$message_id)->update(['stripe_session_id'=>$this->stripe_session_id ]);
$this->emit('PayonStripe',['ssid'=>$session->id]);
}
I imagined adding something like the below code but the variables are not recognized by the stripe API during the rquest.
'transfer_data' => [
'destination' => '{{CONNECTED_STRIPE_ACCOUNT_ID}}',
],

Yes! You can set these within the payment_intent_data parameter:
$session = \Stripe\Checkout\Session::create([
'payment_method_types' => ['card'],
'line_items' => [...],
'mode' => 'payment',
'success_url' => 'http://example.com/success',
'cancel_url' => 'http://example.com/cancel',
'payment_intent_data' => [
'application_fee_amount' => 100, // optional
'transfer_data' => [
'destination' => 'acct_123',
],
],
]);
A number of parameters are exposed this way in Checkout, such as metadata for the payment intent and similar data for subscription mode under subscription_data.
