FAQ
Which payment gateways can you integrate?
I integrate Stripe, PayPal, Paddle, and Razorpay. If you need a different gateway, contact me before ordering and I'll confirm availability.
How long does payment gateway integration take?
A basic one-time payment integration takes 1–2 days. A full subscription billing setup with webhooks, invoices, and refund flows takes 3–5 days.
Will you handle webhooks for payment events?
Yes. I implement webhook listeners for all critical payment events — successful payment, failed payment, subscription renewal, cancellation, and refund. This ensures your app stays in sync with payment status in real time.
Is the integration secure? Will card data be stored on my server?
No card data is ever stored on your server. I use tokenization (Stripe Elements / PayPal SDK) so sensitive data goes directly to the payment provider. Your server only handles tokens and order metadata.
Can you set up recurring subscription billing?
Yes. Subscription billing with multiple plans, free trials, upgrade/downgrade, and automatic renewal is included in Standard and Premium packages.
Which frameworks and languages do you support?
I work with Laravel (PHP), Next.js, and plain PHP. For other stacks, contact me to confirm compatibility before ordering.
What happens if a payment fails?
I implement retry logic and failure handling — the user gets notified, their subscription is paused after grace period, and they can update their payment method. This is fully automated via webhooks.
