API Integration

Make your systems talk to each other

We connect CRMs, ERPs, payment gateways, logistics platforms, and third-party APIs into one reliable, observable data flow — so information moves the moment it should, with zero manual re-entry or data silos.

About this service

Most businesses run on a patchwork of tools that don't share data — your CRM doesn't know what your billing system knows, and your support desk is always one step behind. We design and build the integration layer that ties everything together using REST, GraphQL, webhooks, message queues and event streams. Every connector we build includes retries, idempotency, error logging and live monitoring so nothing silently breaks at 2am.

What we deliver

Everything included

Every project is scoped specifically for you — these are the core capabilities that underpin this service.

01

Third-Party & SaaS APIs

Stripe, PayPal, bKash, Nagad, Shopify, Salesforce, HubSpot, Twilio, Google Workspace, QuickBooks and 200+ more — connected, tested and documented end to end.

02

Custom Middleware & Adapters

A clean, versioned integration layer that maps, transforms, validates and routes data between systems that were never designed to communicate.

03

Webhooks & Event Streams

Real-time, event-driven synchronisation with HMAC signature verification, configurable retry logic, dead-letter queues and Slack/email alerting on failure.

04

Legacy & Internal Systems

Wrap older in-house software — FTP, SOAP, Excel uploads, on-prem databases — in modern, secure APIs without a costly full rewrite.

05

Payment Gateway Integration

End-to-end payment flows with Stripe, PayPal, bKash and Nagad including webhook reconciliation, refund handling and PCI-safe data flows.

06

Real-Time Data Pipelines

Kafka, RabbitMQ and SQS-backed event streams for high-volume data that must flow reliably across microservices or third-party platforms.

How we work

A clear path from idea to live

    Design

    Define API contracts, authentication, error codes and the canonical data model.

  3. 3

    Build

    Develop connectors with full validation, idempotency and logging.

  4. 4

    Harden

    Add retries, rate limiting, circuit breakers, logging and alerting.

  5. 5

    Test

    End-to-end integration and failure-path testing in a staging environment.

  6. 6

    Operate

    Monitor live data flows, respond to incidents and iterate as you scale.

Why it matters

Outcomes you can measure

Real, practical results — not buzzwords. Here's what this service changes for your business.

No more manual re-entry

Data flows automatically between tools the instant it's created — no copy-paste, no spreadsheet imports.

Real-time data accuracy

A single source of truth across all your systems means every team always works with current information.

Resilient by design

Built-in retries, dead-letter queues and monitoring mean failures are caught and recovered — not silently lost.

Scales with your growth

Event-driven architecture handles 10 events or 10 million without rewiring your integration layer.

Faster product delivery

When your tools talk to each other automatically, your team spends time building — not fixing data problems.

Audit & compliance ready

Every data movement is logged with timestamps, source and destination — ready for audits or debugging.
