Über diesen Service
Need payments that work on the first live transaction? I integrate payment gateways into Android apps and websites, with the security details done properly.
What I integrate
- Razorpay, Stripe, PayPal, PhonePe, Cashfree, Instamojo, UPI
- Android (Kotlin/Java) and web (Laravel/PHP)
- Webhooks, subscriptions, refund handling (Premium)
How I keep it secure
- Orders created on your server, never in the app
- Webhook signature verification
- Secret keys kept out of the app code
- Error and failed-payment handling
What I need from you
- Your gateway test keys (never live keys)
- Access to the app or site code
- Your payment flow in 2-3 lines
How it works
- Message me your requirements
- I confirm scope and price
- I deliver tested, commented code in 2 days
- Revisions within the agreed scope
Clear communication in English and Hindi. Message me before ordering so we can confirm your gateway and setup.

Do you need my live API keys?
No. I build and test with your test keys, and you add the live keys yourself at launch.
What if my gateway account is not approved yet?
I can build and test in sandbox mode while approval is pending.
Can you handle refunds and failed payments?
Yes, in the Premium package, including webhook-based status updates.
Do you support both app and website?
Yes: Android in Kotlin or Java, and websites in Laravel or PHP.
