Frequency Asked Questions (FAQs)
Does Stripe Pro keep customers on my website during checkout?
Yes. Stripe Pro uses an embedded payment form, so customers complete the payment directly within your OpenCart checkout without being redirected to an external page.
Is this extension secure and PCI compliant?
Yes. Stripe handles all sensitive card data using its secure infrastructure. Your OpenCart store never stores card details, making the payment flow PCI-friendly and secure.
Does it support 3D Secure authentication?
Yes. Stripe Pro automatically supports 3D Secure authentication. If the customer’s bank requires it, Stripe will handle the verification step during checkout.
Do I need to configure webhooks?
Yes. Webhooks are required for reliable payment confirmation. They ensure your OpenCart store receives accurate payment status updates even if the customer closes the browser.
What happens if the webhook is not configured?
Without webhooks, some payments may not update correctly or instantly. The extension includes a fallback check, but webhook setup is strongly recommended for accuracy.
Can I test payments before going live?
Yes. Stripe Pro supports both Test Mode and Live Mode. You can fully test the payment flow using Stripe test cards before accepting real payments.
Does it support guest checkout?
Yes. The extension works for both guest users and registered customers without any issues.
Can customers retry failed payments?
Yes. If a payment fails, customers can retry the payment without creating duplicate orders.
Does it support multiple currencies?
Yes. Stripe Pro supports multiple currencies and correctly handles different currency formats, including zero-decimal currencies.
Will this improve my conversion rate?
Yes. Since customers stay on your website and experience a smooth checkout process, many stores see improved conversion rates and reduced cart abandonment.
Can I track transactions inside OpenCart?
Yes. The extension provides a Transactions tab and Webhook Logs, allowing you to monitor payments, debug issues, and track all Stripe activities.
Is HTTPS required?
Yes. HTTPS is required for live payments to ensure secure communication and compliance with Stripe requirements.
Does the extension store any sensitive payment data?
No. All sensitive data such as card numbers is handled by Stripe. Your OpenCart database only stores payment references and status information.
Is this better than Stripe Checkout?
Stripe Checkout redirects customers to a hosted page, while Stripe Pro keeps everything inside your store. This provides a more seamless experience and better brand consistency.
What payment methods are supported?
Stripe Pro supports cards and other Stripe-supported payment methods through the Payment Element, depending on your Stripe account configuration.
Which Stripe integration method is used in this extension?
Stripe Pro uses Stripe Payment Element with PaymentIntents API, which is the latest and recommended integration method by Stripe. It replaces older token or source-based implementations.
How is the PaymentIntent created and managed?
The PaymentIntent is created server-side using the OpenCart order details. It includes order ID, amount, currency, and customer data.
The extension reuses an existing PaymentIntent when possible to prevent duplicate payments and ensures consistency.
How does the extension prevent duplicate payments or order updates?
The extension uses multiple layers of protection including idempotency keys during payment creation, tracking of unique Stripe event IDs, and internal order event logging. These combined mechanisms ensure that the same payment or webhook event does not update an order more than once.
How are webhooks verified?
Webhook requests are verified using Stripe’s signature validation system. If the signature does not match or the request appears invalid, it is rejected immediately to prevent unauthorized updates.
What happens if webhook events are delayed or missed?
If a webhook is delayed, the extension performs a fallback verification when the customer returns to the store after payment. This helps ensure the order is updated correctly, although webhook confirmation remains the most reliable method.
How is security handled in the payment flow?
All sensitive payment data is handled by Stripe using Stripe.js, and it never touches your OpenCart server. Only non-sensitive information like the publishable key and client secret is sent to the browser, while secret keys remain securely stored on the server.
Does the extension support manual capture (authorize only)?
Yes, the extension supports both automatic capture and manual capture. In manual capture mode, payments are authorized first and can be captured later from the Stripe dashboard, allowing more control over order processing.
How are Stripe customers handled?
For logged-in users, the extension links them to a Stripe customer and reuses it for future transactions. For guest users, a temporary customer record is created for each order. Customer details are updated automatically during each payment attempt.
How does the extension handle currency and amount conversion?
The extension uses the OpenCart order currency and converts the amount into Stripe’s required format. It correctly handles minor units and also supports zero-decimal currencies, ensuring accurate payment processing.
What validation is performed before marking an order as paid?
Before updating an order, the extension verifies key details such as order ID, PaymentIntent ID, amount, currency, and payment status. This ensures that only valid and matching transactions are accepted.
Where are logs stored and what do they contain?
Logs are stored in the OpenCart log directory and include useful information like order ID, PaymentIntent ID, and event types. Sensitive information such as API keys or card data is never stored in logs.
How does the extension handle failed payments?
When a payment fails, the extension updates the order status accordingly and allows the customer to retry the payment. This helps reduce order loss and improves the checkout experience.
Can the extension work with custom checkout or one-page checkout?
The extension works with standard OpenCart checkout flow. It can also work with most custom checkout solutions, although some themes or heavily modified checkouts may require minor adjustments.
Does it support both PHP 7.4 and PHP 8+?
Yes, the extension is compatible with PHP 7.4 as well as PHP 8 and above, making it suitable for modern hosting environments.
How are API keys managed securely?
API keys are stored securely within OpenCart settings and are never exposed to the frontend. The extension also validates key formats and keeps test and live credentials completely separate to avoid configuration mistakes.
