Custom Module and Integration Development Services

Özel modül API ve yazılım entegrasyonu geliştirme

We build custom modules that fill the gaps in your existing e-commerce, web or enterprise software, and integrations that move data securely between systems. We add the functions you need in a controlled way, without needlessly replacing the platform you already run.

We build payment, shipping, accounting, ERP, CRM, marketplace and third-party service connections on OpenCart, WooCommerce, WordPress, PrestaShop, Magento and custom software. Where off-the-shelf plugins cannot express your business rules, we develop entirely bespoke solutions.

Our Custom Module Development Services

We develop each module in line with the platform’s standards, version and existing customisations.

E-Commerce Modules

We build modules for custom pricing, campaigns, product options, checkout steps, dealer management, payment rules, shipping calculation, reporting and admin panel needs. Potential conflicts with your current theme and plugins are reviewed before work starts.

WordPress and CMS Plugins

On WordPress and other content management systems we build custom forms, user areas, data transfer, content feeds, third-party service connections and admin screens, focused on the actual need rather than adding more plugin weight.

Enterprise Software Modules

We develop additional screens, reports, approval flows and automation modules for ERP, CRM, accounting or custom business applications, designing permissions and activity logging to match the existing system.

API and System Integrations

We plan the full connection so that different systems exchange data reliably and securely.

Payment and Finance Integrations

We connect virtual POS, payment providers, bank transfer notification, instalments, refunds and payment status flows to your platform. Security, error handling and transaction verification follow the payment provider’s technical requirements.

Shipping and Logistics Integrations

We automate shipment creation, barcode generation, shipping labels, tracking numbers, delivery status and rate calculation. Selection rules can be developed for multiple carriers or warehouses.

ERP, Accounting and CRM Integrations

We move product, stock, customer, order, invoice and account information between the relevant systems, making the direction of flow, the master data source and the update frequency explicit.

A Dependable Integration Architecture

Integrations need to hold up not only on day one, but under heavy use and during temporary connection failures.

Data Validation and Mapping

We check the fields sent and received, and make sure product codes, customers, taxes, prices, variants and statuses map correctly between systems.

Queueing, Retries and Error Logs

We build queue structures that keep heavy processing from overloading the system, controlled retries for temporary failures, and error logs your team can actually monitor.

Version and Performance Compatibility

We plan development around your software version and server capacity, identify the areas updates could affect, and provide maintenance and adaptation support when needed.

Modules and Integrations We Build

Depending on your project, we can build custom solutions that complete your existing system in these areas:

  • Virtual POS, payment provider and instalment modules
  • Shipping, courier, barcode and delivery integrations
  • Accounting, ERP, CRM and inventory connections
  • Trendyol, Hepsiburada, Amazon and other marketplace integrations
  • SMS, email, notification and verification services
  • Custom product, price, campaign and order rules
  • Admin panel, reporting and data export tools
  • External API, web service and file-based data transfer

How a Module and Integration Project Works

1. Technical Review

We review the software, version, plugins, server environment and the technical documentation of the service to be connected, and clarify the requirement and its likely impact on your current system.

2. Data Flow and Scope Plan

We define which data is taken from where, where it is sent, which rules apply and what happens when something fails.

3. Development and Testing

Wherever possible we build the module or integration in a test environment, checking sample transactions, permissions, load, malformed data and connection-loss scenarios.

4. Deployment and Support

We deploy the approved work to the live system, monitor the first transactions and hand over the operating knowledge. We can provide adaptation and maintenance support as services or platforms are updated.

Why AtayaLabs for Module and Integration Development?

Unlike simply installing a ready-made plugin, we weigh your business rule, your data security and the long-term maintainability of your system together.

  • Development experience across multiple e-commerce and CMS platforms
  • A technical approach built around APIs, data mapping and workflow
  • Controlled development that preserves your existing customisations
  • Error logging, validation and performance mechanisms
  • Maintenance and version adaptation support after deployment
