FAQ
What platforms or tech stacks do you support?
I support most modern tech stacks, including React, Next.js, Vue, Angular, Node.js, Python (Django, Flask), PHP (Laravel), and mobile apps using Flutter or React Native. If you’re using a different framework, feel free to message me to confirm compatibility.
Which payment gateways can you integrate?
I can integrate Stripe, PayPal, Flutterwave, M-Pesa, Paystack, Coinbase, Square, Razorpay, and other major gateways. If your preferred gateway isn’t listed, I can evaluate and integrate it if APIs are available.
Can you implement subscriptions and recurring payments?
Absolutely. I support one-time payments, recurring billing, subscription plans, usage-based billing, and trial periods depending on the payment provider’s capabilities.
Will my payment system be secure and PCI-compliant?
Yes. I follow secure coding best practices, use official SDKs or APIs, implement server-side validation, and ensure sensitive data is never exposed or stored improperly.
Do you support webhooks and payment status tracking?
Yes. I configure webhooks for real-time payment updates such as successful payments, failed charges, refunds, and subscription events.
Will I get documentation or guidance after delivery?
Yes. You will receive basic documentation or usage instructions, plus guidance on how to manage keys, switch environments, and monitor transactions.
Can you integrate M-Pesa for Kenyan or African clients?
Yes. I specialize in M-Pesa integrations, including STK Push, C2B, B2C, and webhook callbacks, as well as Flutterwave and Paystack for Africa-focused platforms.
What do you need from me to start?
I typically need: • Your project source code or repository access • Payment gateway API keys (test mode) • Your business/payment requirements • Callback or webhook URLs • Hosting or deployment access (if needed)
Do you offer post-integration support?
Yes. I provide free post-integration support for bug fixes and minor adjustments after delivery.
How long does the integration take?
Simple integrations usually take 1–3 days. More complex setups (subscriptions, multiple gateways, webhooks, dashboards) may take longer depending on scope.
