API Integration & Middleware Development UAE
Payment gateways. ERP connectors. Government APIs. WhatsApp Business. Shipping providers. Internal services. We connect your stack to everything else — with clean middleware, real error handling, and webhook reliability.
Integration that doesn't break at 3am.
Idempotent endpoints, retry logic, dead-letter queues, observability. Production integration patterns that survive real traffic.
Payment gateway integration
Telr, Network International, Checkout.com, Stripe, Tabby, Tamara, Apple Pay, Google Pay.
ERP integrations
Odoo, SAP, Dynamics, Zoho, NetSuite — both as source and destination of data.
WhatsApp Business API
Official Cloud API or on-premise, with template management, opt-in flows, and CRM sync.
Shipping API integration
Aramex, DHL, FedEx, Naqel, local couriers — quotes, booking, tracking, labels.
Government API integration
UAE Pass, MOHRE, DED, RERA, Ejari, Dubai Trade, FTA, customs.
Third-party API integration
Any REST/GraphQL/SOAP/XML-RPC API — properly wrapped with retry, auth, and logging.
Middleware development
ESB-style middleware when systems can't be modified directly — protocol translation, routing.
Webhooks & automation
Reliable webhook infrastructure — signing, replay, dead-letter handling, observability.
Integration monitoring
Dashboards, alerting, SLA tracking — so you know when an upstream provider degrades.
Integration done with discipline.
Most integration issues are operational, not technical. Our process forces the operational thinking upfront.
We document both API contracts in detail — auth, rate limits, error codes, sandbox/prod differences.
Build with idempotency, exponential backoff, circuit breakers, and structured logging from day one.
We deliberately break things — network failures, timeouts, malformed responses — and verify recovery.
Deploy with monitoring on every external call, SLA tracking, and alerting before users notice issues.
Why most API integrations break in production
Building an integration that works on a sunny afternoon is easy. Building one that survives 18 months of production traffic, intermittent upstream failures, retry storms, schema changes, and the inevitable 3am incident — that's the actual job. Most teams underestimate this until they're firefighting.
Three patterns separate production-grade integrations from the rest:
Idempotency as a first principle
Networks fail. Webhooks deliver twice. Users double-click. If your integration creates duplicate records or double-charges customers when this happens, you've built a fragile system. Every endpoint that creates state needs an idempotency key — a deterministic identifier that prevents duplicate side effects on retry. Most teams add this after the first incident; we add it on day one.
Treating errors as data
The difference between "the integration is down" and "the integration is healthy but the upstream provider is returning 503s on 4% of requests" is the difference between firefighting and proactive ops. Every external call needs structured logging — request ID, latency, status, error code, retry count. Aggregated into dashboards, these tell you exactly which upstream provider is degrading before customers feel it.
Webhook reliability
Webhooks are the most under-engineered part of most integrations. They need signature verification (against forgery), replay tolerance (in case the network drops and the provider retries), dead-letter handling (for the 1% that fail processing), and ideally a replay endpoint so you can re-process historical events without involving the upstream provider. Without these, you'll lose data and not know it.
The engineers we work with have built integrations for fintech, eCommerce, logistics, and SaaS — environments where integration failure means real money lost. They write integrations the way payment companies write integrations: defensively, with observability, with retry, with rollback.
If you've got an existing integration that's been causing pain — duplicate orders, missed webhooks, slow batch jobs, mysterious data gaps — we can do a 1-week audit and produce a remediation plan. Usually the fixes are smaller than you expect.
