Custom payment gateway integrations for any bank, website or app.
We develop custom integrations for local bank acquiring gateways and international payment processors into WordPress, WooCommerce, Next.js, Laravel, and custom mobile apps. We are developers, not a payment gateway. We take your bank documentation, write custom code for your platform, test in sandbox, and you verify the live payment.
// CyberSource Flex Microform Tokenization
const flex = new Flex(captureContext);
const microform = flex.microform({
styles: {
input: { fontSize: '15px', color: '#011e5b' }
}
});
const numberField = microform.createField('number');
const securityCode = microform.createField('securityCode');
// Generates transient token -> Zero PCI-DSS scope
microform.createToken((err, token) => {
if (token) authorizePayment(token); // 3DS2 Ready
});
Direct Acquiring Bank Bridges
Connecting commercial banks to custom stores with 3D Secure 2.2 authentication.
We develop from raw bank API documentation.
When tier-1 commercial banks hand you credentials for Mastercard MPGS, Visa CyberSource, or proprietary bank endpoints, they rarely provide ready-to-use CMS plugins. We write clean, secure custom code to bridge your website directly with your bank.
How We Deliver Your Integration
From raw bank documentation and sandbox testing to staging release. You check the live connection on your side, payment clears, work done.
Documentation & Sandbox Ingestion
Client shares bank credentials and API specifications
You share your bank or payment gateway API documentation (PDF, portal link, or Swagger/Postman) along with sandbox/test keys (Merchant ID, API passwords, test certificates, and IP whitelist requirements).
- Receipt of test Merchant ID & Gateway endpoints
- Review of API specification (REST, SOAP, or ISO 8583)
- Server IP whitelisting with the bank network
- Mutual Non-Disclosure Agreement (NDA) signed upfront
Platform & Security Scope Audit
Technical analysis of your CMS, custom stack, or mobile app
We evaluate your target platform—WordPress / WooCommerce custom plugin, Magento, PrestaShop, or custom Next.js/Laravel app where full code access is available. We determine the optimal integration pattern (Hosted Checkout vs. Drop-in iframe vs. Direct S2S) to keep your business strictly in PCI-DSS SAQ-A scope.
- CMS version hooks & headless compatibility verification
- Decision on checkout UX: embedded fields vs hosted redirect
- PCI-DSS SAQ-A scope verification (zero card data on server)
- Resilient webhook listener & state machine design
Custom Integration Plan & Fixed Quote
Clear milestone timeline, deliverables, and fixed pricing
We provide a transparent development roadmap with defined delivery checkpoints. You receive a guaranteed fixed-price quote with zero hidden hourly billing, detailing exact test cases and delivery schedules.
- Detailed scope of work and edge-case coverage
- Fixed milestone delivery schedule (typically 3 - 5 business days)
- Specification of supported payment methods (Cards, Apple Pay, 3DS2)
- Clear deliverables: source code, installation guide, admin settings
Development & Webhook Implementation
Writing clean, modular, PSR / ES-compliant code
Our senior payment developers build the custom module or API service directly in your staging environment or a private git branch. We build robust error handling, cryptographic signature verification (HMAC-SHA256), and replay-proof webhook consumers.
- Native integration into store checkout flow or mobile SDK
- Tokenization & 3D Secure 2.x frictionless/challenge handling
- Idempotent webhook callbacks with replay prevention
- Comprehensive transaction audit logging in admin panel
Rigorous Sandbox QA & Edge-Case Testing
Validating every transaction status before live rollout
We execute a complete battery of bank-specified test scenarios using test cards to verify all operational pathways: successful authorizations, 3DS OTP challenges, insufficient funds, expired cards, network timeouts, and refund handling.
- Test card executions: Visa, Mastercard, and regional debit rails
- Verification of 3DS OTP verification and challenge fallback
- Testing webhook event processing during network latency
- Customer order status transitions (Pending -> Paid -> Shipped)
- Completion of bank-required UAT certification questionnaire
Release & Client Live Connection Check
We deploy to production, client verifies live connection & payment, work done
Once sandbox verification is completed, we configure the production environment and release the integration. You (the client) test a real live card payment on your side to confirm end-to-end clearing into your merchant bank account. Once live connection is verified and payment is done, work is done!
- Production credentials configured & debug logs restricted
- Staging / Production release delivered to client
- Client verifies live connection and tests live payment on their side
- Payment confirmed, work done, full source code handover & warranty
Zero Raw Card Data On Your Servers (PCI-DSS SAQ A)
All integrations are developed using bank-approved Hosted Fields, Tokenized Sessions, or Secure Redirection. Your web server never touches, transmits, or stores sensitive cardholder data.
A fully integrated suite of payment gateways.
We develop directly to gateway REST and S2S APIs, implementing tokenization, 3D Secure 2.2, and automated webhook reconciliation.

Frequently asked questions.
Q.Our local bank gave us API documentation (PDF) and sandbox credentials, but no plugin exists for our CMS. Can you build it?
Yes, this is our core specialization. Many commercial banks license engines like Mastercard MPGS, Visa CyberSource, or run proprietary legacy SOAP/REST gateways without providing pre-built WordPress or WooCommerce plugins. We do not sell pre-made generic plugins. We take your bank documentation, write a clean bespoke plugin specifically for your website, test it in sandbox, deliver it to your staging environment, and you verify the live connection.
Q.How do you ensure our website complies with PCI-DSS regulations?
We architect integrations using bank-approved Hosted Fields, Hosted Session iframes, or Secure Acceptance redirect forms. Sensitive credit card numbers are captured directly by the payment processor's hardened servers, ensuring your web server never touches, transmits, or stores raw card data. This reduces your PCI compliance overhead to the simplest self-assessment questionnaire (PCI-DSS SAQ A).
Q.What platforms do you support?
We exclusively work on platforms where source code changes and custom plugin installations are possible: WordPress & WooCommerce custom plugin development, Next.js / React, Laravel (PHP), Node.js, Magento 2, PrestaShop, Python Django, and Mobile SDKs (Flutter & React Native). We do not work on locked proprietary platforms where custom backend code cannot be installed.
Q.What is the standard turnaround time for a custom gateway integration?
Standard CMS integrations (e.g., WooCommerce, Magento, PrestaShop) typically require 3 to 5 business days once sandbox credentials and API documentation are accessible. Complex enterprise platforms, multi-currency marketplace splits, or custom mobile SDKs (Flutter/React Native) are delivered in 5 to 10 business days with defined milestone checkpoints.
Q.How does the final go-live and payment check work?
We conduct full testing in the sandbox/test environment. Once all edge cases pass and we release the staging/production build, you (the client) test a real live card payment on your side to confirm the connection and money settlement. Once your live test clears into your merchant account, payment is done and the work is complete.
Q.Who owns the custom code once the integration is complete?
You receive 100% ownership of all custom source code, configuration files, and documentation. We deliver clean, unencrypted, and well-documented code with no recurring licensing fees.
