API Development & System Integration
Get a QuoteWhen your systems connect properly, your business runs faster and your people work smarter.
At Webtech Nepal, we build the invisible connections that make modern businesses work. An API is just a way for one piece of software to ask another piece of software for information or action. When done right, it means your website can check inventory in real time, your CRM can pull customer data from your sales platform, and your accounting software can record transactions automatically. When done wrong, you get broken connections, data that doesn’t match, and staff spending hours copying information between systems. We do it right: clean, documented APIs that other developers can actually use, secure integrations that protect sensitive data, and monitoring that catches problems before your team notices them.
Whether you need to connect your website to a payment gateway, build an API that mobile apps can use, or stitch together five different business tools into one smooth workflow, we can help. We listen to how your business actually operates, map out where data needs to move, and build connections that are reliable and easy to maintain. No fragile hacks, no undocumented shortcuts, no “it works on my machine” surprises. Just solid plumbing that keeps your digital business running day after day.
Fields of Expertise
We build API and integration solutions that help Nepali businesses automate work, reduce errors, and create seamless experiences for customers and staff. Here’s what we do:
Custom API Development
Built-from-scratch interfaces that let your software talk to other software. We design RESTful and GraphQL APIs with clear endpoints, proper authentication, and comprehensive documentation—so other developers can integrate with your system without guessing how it works.
Third-Party API Integration
Connections to services your business already uses. We integrate with payment gateways, SMS providers, email platforms, map services, social media, accounting software, and logistics systems—making your existing tools work together instead of operating in isolation.
Payment Gateway Integration
Secure connections to local and international payment processors. We integrate eSewa, Khalti, Fonepay, Stripe, PayPal, and bank APIs—handling transaction processing, refund flows, webhook notifications, and reconciliation so your finance team doesn't chase missing payments.
CRM & ERP Integration
Links between your customer database and business management systems. We connect Salesforce, HubSpot, Zoho, SAP, or custom systems—syncing contacts, orders, inventory, and support tickets so every department sees the same accurate information.
E-Commerce Platform Integration
Connections that let your online store talk to fulfillment, accounting, and marketing tools. We sync orders, update stock levels, trigger shipping labels, and record revenue automatically—cutting manual work and reducing the errors that frustrate customers.
Social Media & Marketing API Integration
Automated posting, analytics pulling, and lead capture from social platforms. We connect Facebook, Instagram, LinkedIn, Twitter, and Google APIs—scheduling content, tracking campaigns, and feeding social leads directly into your sales pipeline.
Cloud Service Integration
Connections to AWS, Google Cloud, Azure, and other cloud platforms. We set up file storage, serverless functions, database syncing, and CDN delivery—leveraging cloud power without locking you into one provider's ecosystem.
Legacy System Integration
Modern connections to older software that still runs critical parts of your business. We build middleware, translation layers, and API wrappers that let your legacy database or internal tool communicate with modern apps—extending the life of working systems without full replacement.
Real-Time Data Sync
Live connections that keep information current across platforms. We implement WebSockets, server-sent events, and polling strategies—so when one system updates, all connected systems see the change immediately, not hours later.
Mobile App Backend APIs
Server-side interfaces that power your iOS and Android apps. We build authentication, data fetching, push notification handling, and file upload endpoints—optimized for mobile network conditions and battery efficiency.
Webhook & Event-Driven Architecture
Systems that react automatically when something happens elsewhere. We build webhook handlers, event buses, and message queues—triggering actions like sending emails, updating dashboards, or notifying teams without constant polling or manual checking.
API Documentation & Developer Portals
Clear guides that help other teams use your APIs correctly. We write interactive documentation, provide code examples, and set up sandbox environments—reducing integration time for partners and support burden for your team.

Our Process
Discovery & Planning
We start by mapping how your business actually works: what systems you use, where data lives, who needs what information, and where things currently break or slow down. This shapes our integration strategy, technology choices, and success metrics—so every connection solves a real problem.
System Audit & Mapping
We document your existing software landscape: versions, capabilities, limitations, and data structures. This audit reveals integration points, potential conflicts, and opportunities to simplify before we start building—preventing nasty surprises mid-project.
API Design & Architecture
We design the interface contract: what data gets exchanged, in what format, how authentication works, and what happens when something goes wrong. Good design here prevents endless debugging later. We prioritize security, scalability, and clarity from the start.
Development & Implementation
We write the code that connects your systems. Clean, tested, documented code that handles edge cases gracefully: network timeouts, partial failures, data format mismatches, and rate limiting. We don't just make the happy path work—we make it robust.
Authentication & Security Setup
We implement proper access controls: API keys, OAuth tokens, JWT authentication, IP whitelisting, and encrypted transmission. Your data is valuable and often sensitive; we treat it that way from the first connection request.
Testing & Validation
We test integrations thoroughly: unit tests for individual functions, integration tests for complete flows, load tests for performance under pressure, and failure tests for graceful degradation. We verify data accuracy, timing, and security before anything touches production.
Documentation & Handover
We write clear documentation that your team and future developers can actually use. Endpoint references, authentication steps, error codes, rate limits, and example requests in multiple programming languages. Knowledge that stays with your business.
Deployment & Monitoring
We deploy to production with monitoring dashboards, alert systems, and logging in place. We track response times, error rates, data throughput, and system health—catching issues before they affect your operations or customers.
Maintenance & Evolution
We keep integrations running as APIs update, systems change, and your business grows. Version management, deprecation handling, performance tuning, and new feature additions—ensuring your connections stay reliable as the software landscape shifts.
