I will do payment gateway integration for stripe, paypal, shopify, and more


Level 2
About this gig
Need a developer to integrate a payment gateway that actually works securely, without breaking your checkout or webhooks? I don't just plug in Stripe or PayPal. I integrate a wide range of payment gateways, custom payment APIs, and subscription billing for websites, apps, and SaaS platforms.
Gateways I work with:
- Stripe, PayPal, Shopify Payment, Square, Razorpay, Authorize.Net, Braintree, Mollie, 2Checkout, and many more
- Custom payment APIs, direct bank integrations, and local/regional gateways
- Recurring billing, one-time payments, refunds, disputes, webhooks, sandbox testing
What you get:
- A payment integration mapped to your exact workflow not a copy-paste snippet
- Secure handling of API keys, webhook signatures, and PCI-conscious practices
- Testing in sandbox mode with clear proof of success, failure, refund, and error cases
- Integration with your existing platform: Shopify, WordPress, custom PHP/Node/Python, or any REST-based app
- Clear handover notes so you know exactly what was built
I've worked with dozens of gateways and platforms. If your gateway is rare or regional, send me the documentation, and I'll confirm feasibility before you order.

FAQ
Which payment gateways can you integrate?
I work with Stripe, PayPal, Shopify Payment, Square, Razorpay, Authorize.Net, Braintree, Mollie, 2Checkout, and many other regional or custom gateways. If you have a specific gateway in mind, share its API documentation and I’ll confirm.
Can you integrate a gateway that is not listed in your gig?
Yes. I have versatile experience with many gateways. Just send me the API docs or admin access to the gateway, and I’ll let you know if it’s feasible.
What do I need to provide before you start?
You’ll need to share API keys/credentials securely, platform admin access, endpoint documentation, and a clear description of the required flow (one-time, subscription, refunds, etc.).
Do you test the integration before delivery?
Yes. I test in sandbox/test mode first — success, failure, refund, and webhook scenarios — then guide you through live verification.
Will this work with my existing website or app?
Usually yes. I can integrate with Shopify, WordPress, custom PHP/Node/Python apps, and most platforms that expose REST APIs. Share your stack and I’ll confirm.
How do you handle security?
I use environment variables, never hardcode secrets, verify webhook signatures, and follow PCI-conscious practices. Your keys and customer data are handled carefully.
Do you provide support after delivery?
I provide clear documentation and can help with issues related to the delivered integration. For new features or significant changes, message me first to discuss scope.
