API integration services that connect your systems and keep them in sync
We connect your CRM, ERP, accounting and third-party tools through REST and GraphQL APIs, webhooks and OAuth — with clean data mapping and middleware that keeps records flowing reliably in both directions. Custom API development and integration, engineered in Kuala Lumpur, serving Malaysia and worldwide.
REST & GraphQL · OAuth-secured · you own the integration.
The integration components that make your stack talk
Concrete, engineered deliverables — not a diagram. Depending on scope, an integration project ships some or all of the following.
REST & GraphQL integrations
Connections to any CRM, ERP or SaaS tool that exposes an API — built against its documented endpoints and tested end to end.
Custom API development
When you need your own endpoints, we build REST or GraphQL APIs with authentication, rate limiting and versioned documentation.
Webhooks & event pipelines
Real-time triggers with signature verification, retries and backoff so an event in one system reliably updates the others.
Data mapping & transformation
Field-level mapping between mismatched schemas — formats, units, IDs and record shapes normalised so both sides stay clean.
Middleware & sync layer
An orchestration layer that brokers records between systems, resolves conflicts and keeps a single source of truth in two-way sync.
OAuth & secure auth
OAuth 2.0, API-key and token flows with credentials stored in encrypted secrets and scoped to least-privilege access.
We integrate the platforms your business already runs on — and speak their protocols. Beyond the tools below, we work with Salesforce and SAP, build against REST and GraphQL, secure calls with OAuth, and drive real-time flows with webhooks.
How we engineer an integration that stays reliable
A disciplined engineering process — from mapping the endpoints to monitoring live traffic — so the sync doesn’t break the first time an API changes.
Integrations we build every week
CRM integration
Sync leads, contacts and deal stages between your CRM, website forms and marketing tools — no more manual re-entry.
ERP integration
Push orders, inventory and invoices between your ERP and finance systems so stock and ledgers stay consistent.
Third-party integrations
Wire payments, shipping and support tools together with webhooks so an event in one triggers action in the rest.
Custom REST API
Expose your own data through a documented, authenticated REST or GraphQL API for partners or internal apps to consume.
Transparent scoping, fixed quotes
We don’t sell open-ended retainers. After a free scoping call we map the work and give a fixed price before anything starts. A few factors drive that scope:
Integrations built to survive real APIs
Engineers, not just connectors
We write real integration code, not only drag-and-drop — so edge cases and custom logic are handled properly.
Reliability by design
Retries, backoff, idempotency and logging are built in from the start, so a dropped call never means lost data.
Security-first auth
OAuth, encrypted secrets and least-privilege scopes — credentials are never hard-coded or shared in plain text.
You own everything
Built in your accounts, with your credentials, handed over with documentation. No lock-in to us.
Any stack, any protocol
REST, GraphQL, SOAP or webhook — CRM, ERP, database or SaaS — we connect what you already run.
KL-based, globally minded
On the ground in Kuala Lumpur, building and maintaining integrations for clients across Malaysia and worldwide.
Where integrations lead next
API integration questions
Which systems and third-party APIs can you integrate?
Almost anything with an API or webhook. Common ones include CRMs like HubSpot and Salesforce, ERPs like SAP, accounting tools like QuickBooks and Xero, e-commerce platforms like Shopify, payment systems like Stripe, and databases like PostgreSQL and MySQL. If a tool exposes a REST or GraphQL API, we can connect it; where there’s no public API we use webhooks, official SDKs, or middleware platforms like Zapier and Make.
Do you build against REST or GraphQL APIs?
Both, plus SOAP and webhook-based endpoints where a vendor still uses them. We choose per integration: REST for most CRM, ERP and SaaS APIs, GraphQL where a platform offers it and we need to fetch related data in one call. We test every endpoint in Postman before wiring it into your workflow.
What if a tool we use has no public API?
We have options. Many tools expose webhooks or a hidden API we can use safely; others integrate through iPaaS connectors on Zapier or Make, a database-level sync, file or CSV exchange, or — as a last resort — a resilient automated data-capture layer. In scoping we confirm the most stable route before committing to it.
How do you handle API authentication and security?
We use each provider’s recommended auth — OAuth 2.0, API keys, or signed tokens — and store credentials in encrypted secrets, never in code. Traffic runs over HTTPS, webhook payloads are signature-verified, access is scoped to the minimum permissions needed, and sensitive write actions can sit behind human approval. Nothing is hard-coded or shared in plain text.
How do you keep data in sync and avoid duplicates or conflicts?
We define a clear field mapping and a source of truth for each record, then use unique IDs, idempotency keys and deduplication rules so the same event never writes twice. Syncs run on schedules or real-time webhooks with retry-and-backoff, and every run is logged so a failed call is caught and replayed rather than silently lost.
How long does an API integration project take?
A single, well-documented two-system integration can be live in days to a couple of weeks. Multi-system middleware with custom data mapping, complex auth or ERP endpoints takes longer. After a free scoping call we give a fixed timeline and quote before any build starts.
Who owns the integration code and credentials after handover?
You do. Integrations are built in your accounts and connect through your own API credentials. On handover you receive the workflows, any custom middleware code, the data-mapping documentation and full ownership — you are never locked into us to keep it running.
What happens when a third-party API changes or breaks?
Vendors deprecate endpoints and rotate versions, so we build in monitoring and alerting that flags failed calls or schema changes early. Under a support arrangement we update the integration when an API version is retired; without one, we hand over documentation so your team can maintain it, and we’re available to help when needed.
Do you work with businesses outside Malaysia?
Yes. We are based in Kuala Lumpur and build and maintain API integrations for clients across Malaysia and internationally, remotely.
