Custom API Integration Services

API integrations must be precise, secure, and reliable. At Aimit, we follow a structured process to ensure your systems communicate seamlessly, automate workflows, and deliver long-term business value. From discovery to deployment, every step is handled with transparency and technical excellence.

Our Custom API Integration Process

Here are two examples of custom software solutions we developed for our clients, each paired with mobile applications to ensure full accessibility and scalability.

Some of Our Work

Modern businesses rely on multiple platforms to operate from CRMs and ERPs to payment systems, logistics providers, and cloud applications. Without proper integration, these tools often become disconnected systems, leading to manual work and inefficiencies. At Aimit, we specialize in developing custom API integrations that connect your systems into one seamless ecosystem, ensuring real-time data exchange, automation, and business agility. Instead of working with fragmented apps or limited connectors, our team builds secure, scalable, and fully documented APIs tailored to your unique workflows. Whether you need to integrate payment gateways, marketing platforms, accounting tools, or third-party SaaS products, we ensure that every connection is reliable, compliant, and future-proof. 
 <h3>What We Deliver</h3>
 <ul>
 <li>Payment & billing integrations (Stripe, PayPal, Square, banking APIs)</li>
 <li>CRM, ERP, and HR system connections</li>
 <li>Logistics & shipping APIs for real-time tracking and carrier updates</li>
 <li>Marketing & analytics integrations with Google Ads, Meta, and BI tools</li>
 <li>Cloud service integrations (AWS, Azure, Google Cloud)</li>
 <li>Custom API design & documentation for internal systems</li>
 </ul>
 Our API integration projects typically start from $50,000 and scale based on complexity and the number of systems involved. To ensure transparency, we work in phases starting with requirements analysis and technical documentation, followed by integration development, testing, and deployment. Each step is carefully managed to guarantee stability, security, and compliance with global standards like GDPR, PCI DSS, and HIPAA. All integrations are built exclusively for your company. The documentation, architecture, and code belong entirely to you, ensuring independence and long-term reliability. With our expert development team based in Armenia, we combine enterprise-grade expertise with competitive pricing.

Custom API Integration

Every successful integration starts with understanding your systems, workflows, and objectives.

Identify business needs, integration goals, and expected outcomes.

Analyze your software ecosystem (CRMs, ERPs, payment gateways, logistics tools, etc.).

Define which systems need to connect, what data flows are required, and how errors should be handled.

Produce clear specifications (endpoints, authentication methods, data models).

Outcome: A documented integration blueprint aligning business and technical requirements.

Business Analysis & Documentation

If third-party APIs exist, we design connections around them. If not, we create custom APIs from scratch.

Evaluate third-party APIs or design custom endpoints.

OAuth, JWT, token-based access, encrypted data transfer.

Define direction (one-way, two-way sync) and error handling.

Ensure APIs can handle current and future data loads.

Outcome: A secure, efficient integration architecture tailored to your business.

API Design & Architecture

This is where the APIs are engineered and connected.

Connect payment gateways, shipping APIs, CRMs, marketing platforms, or internal systems.

Standardize and clean data so systems communicate correctly.

Build retry logic, logging, and alerts for failures.

Outcome: Fully functional, tested integrations ready for validation.

Integration Development

API integrations must be thoroughly tested to avoid data loss or downtime.

Check response time under different loads.

Verify encryption, access control, and compliance (GDPR, PCI DSS, HIPAA if relevant).

Ensure multiple systems work together as expected.

Outcome: A reliable, secure integration with minimal risk of failure.

Testing & Quality Assurance

Deploy integrations in a safe test environment.

Launch integrations with minimal downtime.

Set up dashboards, error logs, and notifications for real-time tracking.

Provide API documentation for future maintenance.

Outcome: Live, monitored integrations with full visibility and documentation.

Deployment & Monitoring

Keep integrations compatible with API changes.

Rapid response to downtime or API changes.

Add new endpoints, data flows, or third-party connections.

Prepare integrations for higher traffic, global users, or additional systems.

Outcome: A future-proof integration that adapts to new technologies and business growth.
