High-Throughput APIs & Seamless Third-Party Integrations.
Connect your digital ecosystem effortlessly. SmartEdge designs, develops, and documents high-speed RESTful and GraphQL APIs capable of handling millions of requests with sub-100ms latency.
Solving the Core Friction in API Development & Integration.
Here is how we turn common operational roadblocks into competitive technical advantages.
The Common Challenges You Face
Disjointed Systems & Data Silos
Different software tools across your business unable to communicate or share real-time transaction data.
Brittle, Unreliable Third-Party Connections
Third-party API downtime causing data loss, transaction failures, and customer frustration.
Lack of API Documentation & Security
Unversioned, undocumented endpoints exposing sensitive customer data and creating security vulnerabilities.
How SmartEdge Bangladesh Delivers the Solution
Standardized OpenAPI / Swagger Specs
Fully documented, version-controlled endpoints with automated request and response schema validation.
Resilient Queue & Webhook Processors
Idempotent event consumers with exponential retry logic, dead-letter queues, and failure alerting.
Bank-Grade API Security Standards
OAuth 2.0, JWT authentication, rate limiting, request signing, and IP whitelisting.
Features & Engineering Highlights
Built with uncompromising security, performance benchmarks, and modularity.
High-Speed Caching Layer
Redis cache integration providing sub-50ms responses for high-frequency catalog and pricing endpoints.
Webhook Ingestion & Dispatch
Scalable event publishers notifying external partner software of key order, payment, and status changes.
Payment Gateway Connectors
Pre-built connectors for Stripe, PayPal, SSLCommerz, bKash, Nagad, and international merchant banks.
Comprehensive Rate Limiting & Telemetry
Token-bucket rate limiters preventing API abuse with real-time error tracking and latency metrics.

Our 6-Step Delivery Lifecycle for API Development & Integration
API Contract & Schema Design
Specifying data contracts, error payloads, and REST/GraphQL schemas.
Core Endpoint Engineering
Writing type-safe endpoint logic, database transactions, and middleware.
Security & Authentication Layer
Implementing OAuth2/JWT tokens, cryptographic validation, and rate limits.
Load & Concurrency Testing
Benchmarking endpoints with simulated bursts of 10,000+ simultaneous requests.
Documentation & Sandbox
Publishing interactive developer documentation and staging sandbox environments.
Production Deployment
Deploying behind AWS API Gateway / Cloudflare with active latency telemetry.
Frequently Asked Questions About API Development & Integration
Do you support GraphQL or REST?
We support both! We often recommend REST for standardized resource operations and third-party public APIs, and GraphQL for complex frontend data requirements with nested relations.
How do you handle API rate limits from third parties?
We build intelligent token-bucket queue workers (BullMQ/Redis) that pace outgoing requests precisely within third-party provider limits.
