API & System Integration

Make your software work together — custom APIs, payment gateways, CRM and ERP integrations and data synchronisation between the tools your business depends on.

API & System Integration

Most businesses use many tools: a website, a CRM, an accounting package, payment providers, email platforms and more. When they don’t share data, people end up copying information by hand, and mistakes creep in. Netra Code builds APIs and integrations that connect your systems so data moves automatically and accurately.

Our integration services

Custom API development

We design and build REST APIs (and GraphQL where it fits) for your applications, with authentication, rate limiting, versioning and clear documentation in OpenAPI format so other developers can use them easily.

Payment integrations

Card payments, wallets and bank transfers integrated into websites, apps and billing systems, including payment confirmation webhooks and reconciliation.

Business system integrations

Connect your website or app to CRMs, ERPs, accounting software, marketing platforms, shipping providers and communication tools such as email and WhatsApp.

Data synchronisation and migration

Keep records consistent across systems in real time or on a schedule, and move data safely when you switch platforms.

How we make integrations reliable

  • Clear data mapping agreed before development starts
  • Idempotent processing so repeated messages don’t create duplicates
  • Retries and queues for temporary failures
  • Logging and alerts so issues are visible and traceable
  • Automated tests against sandbox environments

Process

  1. Understand the systems, data and business rules involved
  2. Review API documentation and access requirements
  3. Design the data flow and error handling
  4. Build and test in sandbox environments
  5. Launch with monitoring and document everything

Technologies we use

  • REST
  • GraphQL
  • Webhooks
  • OAuth 2.0
  • Laravel
  • Node.js
  • Postman
  • OpenAPI

FAQ

API & System Integration: common questions

An API (application programming interface) lets two pieces of software exchange data. An integration uses APIs so that, for example, a new order in your store automatically appears in your accounting system.

Often yes, through export files, database connections, webhooks or other methods. We assess what is possible and reliable before recommending an approach.

We use secure authentication such as OAuth or API keys stored as secrets, encrypted connections, input validation and logging, and we request only the permissions each integration needs.
