Generating SumUp payment URL with PHP SDK: Tips needed

I’m trying to create a payment link for invoices using the SumUp PHP SDK. Here’s what I’ve done so far:

$sumup = new \PaymentProcessor\Processor([
    'client_id' => '...',
    'client_secret' => '...',
    'auth_type' => 'app_credentials',
]);

$invoiceService = $sumup->getInvoiceService();
$total = $bill->total;
$money = $bill->money;
$invoiceId = $bill->id;
$customerEmail = $bill->customer;
$details = $bill->details;

$invoiceResponse = $invoiceService->generate($total, $money, $invoiceId, $customerEmail, $details);
$transactionId = $invoiceResponse->getResult()->transaction;

The response doesn’t include a payment URL, so I made one:

$paymentUrl = 'https://example.com/pay?invoice='.$invoiceId.'&transaction='.$transactionId;

I set up a basic frontend with the SumUp Card SDK, but I’m unsure how to handle the payment data securely. How can I properly integrate the backend with the SumUp widget to process payments? Any advice on getting a proper payment link or handling card info would be great!

Hey there! I’ve been tinkering with SumUp recently too, and I gotta say, it’s pretty nifty once you get the hang of it. Have you considered using webhooks? They’re super helpful for keeping track of payment statuses in real-time.

I’m curious, what kind of invoices are you dealing with? Are they for a specific type of business or service? It might affect how you set things up.

Oh, and speaking of setup, have you played around in the sandbox environment yet? It’s a lifesaver for testing without the stress of real transactions. What’s been your experience with it so far?

Also, I’m wondering about your frontend. You mentioned using the SumUp Card SDK - what made you choose that over other options? I’d love to hear more about your overall payment flow!

I’ve encountered similar challenges with SumUp integration. From my experience, the createCheckout() method is indeed the way to go. It’s crucial to note that SumUp handles PCI compliance on their end, which is a significant advantage.

For secure integration, consider implementing webhook notifications. This allows SumUp to inform your backend about payment statuses in real-time. You can set this up in your SumUp dashboard and create an endpoint in your application to process these notifications.

Also, don’t forget to properly handle errors and edge cases. SumUp’s API can sometimes be finicky, so implementing robust error handling and logging will save you headaches down the line.

Lastly, make sure to test thoroughly in SumUp’s sandbox environment before going live. It can reveal integration issues that might not be immediately apparent.

hey mate, i’ve used SumUp before. Instead of making ur own payment URL, try using the createCheckout() method from the SDK. it generates a secure checkout link for u. sumthing like:

$checkoutResponse = $sumup->getCheckoutService()->createCheckout([
    'total' => $total,
    'currency' => $money,
    'description' => $details
]);
$paymentUrl = $checkoutResponse->getCheckoutReference();

This way, SumUp handles the payment securely on their end. Hope this helps!
