API & Integration Development

Connect Your Systems, Services & Applications

Modern businesses rarely operate with a single system. Your website may need to communicate with payment gateways, CRMs, accounting platforms, marketing tools, shipping providers, mobile applications, or other business systems.

Praxleo provides API development and integration services that help different platforms communicate, exchange data, and work together more efficiently.

From REST API development and third-party integrations to webhooks, authentication, automation, and custom system connections, we build practical integrations around your business requirements.

Connected Technology

Make Your Systems Work Together

When your tools don't communicate properly, teams often end up manually copying data between systems.

API integration can help automate those processes. Praxleo can connect your websites, web applications, WordPress websites, Laravel applications, Vue.js applications, e-commerce platforms, mobile applications, CRM systems, payment gateways, shipping platforms, marketing tools, and business systems.

The result is a more connected technology environment with less repetitive manual work.

Security

API Authentication & Security

API integrations need appropriate security controls to protect data and prevent unauthorized access.

🔑 API Keys
◆ Bearer Tokens
O OAuth / OAuth 2.0
✓ Authorization
↕ Request Validation
🔒 HTTPS

⌁ Rate Limiting

Security requirements depend on the API, application architecture, data being exchanged, and business use case.

Event-Based Integrations

Webhooks & Event-Based Integrations

Not every integration needs constant polling. Webhooks allow one system to notify another when something happens.

We can implement webhook endpoints, validate incoming requests, process events, and update the appropriate systems.

  • Payment completion
  • New orders
  • Subscription changes
  • Account creation
  • Form submissions
  • Shipment updates
  • CRM events
  • Inventory changes
  • Status updates
Data Connectivity

Data Synchronization

Different systems often need to share the same information. We can help synchronize data around available APIs, business rules, update frequency, and data structures.

  • Customers
  • Products
  • Orders
  • Inventory
  • Payments
  • Leads
  • Appointments
  • Users
  • Content
  • Business records
{ "source": "website", "entity": "customer", "action": "create", "destination": "crm", "status": "synchronized" }

Payment Gateway Integration

Payment processing is a common requirement for websites and applications. We can integrate supported payment gateways into e-commerce websites, custom applications, SaaS platforms, booking systems, and membership platforms.

  • Payment initiation
  • Payment status
  • Callback handling
  • Webhooks
  • Transaction records
  • Order updates
  • Failed-payment handling
  • Refund workflows where supported
◎

CRM & Business System Integration

Connect your website with the tools your business already uses. Instead of manually transferring leads, information can move automatically between systems.

Email, SMS & Notification Integrations

Automated communication can improve how your applications interact with customers.

  • Transactional email
  • Contact form notifications
  • Account notifications
  • Order notifications
  • SMS
  • Verification messages
  • Password reset messages
  • Application alerts
⌘

Custom API Development

Sometimes an existing API doesn't provide everything your business needs. We can build a custom API layer around your application.

  • Business-specific endpoints
  • Custom database access
  • Application integrations
  • Mobile application backends
  • Frontend backends
  • Third-party connections
  • Data transformation
  • Authentication
  • Custom business logic
first_name → customerName
phone → phoneNumber
order_id → orderReference
Integration Layer

API Middleware & Data Transformation

Different systems don't always use the same data structure. An integration layer can transform data between these systems so each platform receives the structure it expects.

  • Data mapping
  • Data transformation
  • Field conversion
  • Validation
  • Normalization
  • Error handling
  • Response transformation
  • Business rules
✓

API Error Handling & Reliability

Integrations can fail for many reasons. An external service may be unavailable, credentials may expire, requests may be rejected, or a third-party API may change.

  • API errors
  • Timeouts
  • Invalid responses
  • Authentication failures
  • Rate limits
  • Network failures
  • Duplicate requests
  • Failed webhooks
  • Unexpected data
  • Third-party service downtime

Where appropriate, integrations can use retries, logging, queues, and fallback handling to improve reliability.

API Documentation

Well-documented APIs are easier to maintain and integrate. Documentation can cover:

  • Available endpoints
  • Request methods
  • Parameters
  • Authentication
  • Request examples
  • Response structures
  • Error responses
  • Webhook events
  • Integration requirements
Business Automation

Automation Through Integrations

APIs can do more than transfer data. They can connect systems and automate repetitive business processes.

We can first understand the existing architecture and then determine the safest implementation approach.

  • Existing API integration
  • API troubleshooting
  • Authentication fixes
  • Endpoint changes
  • Webhook implementation
  • Data synchronization
  • Third-party API updates
  • API migration
  • Performance improvements
  • Integration debugging
  • Custom endpoints
How We Work

Our API & Integration Process

A structured approach helps ensure the integration matches both technical requirements and the business workflow.

01

Understand the Business Requirement

We start by understanding what you want the systems to do and which platforms need to communicate.

02

Review the APIs

We review available API documentation, authentication methods, endpoints, limitations, webhooks, and data structures.

03

Design the Integration

We determine how data should move and where validation, transformation, authentication, and business logic should happen.

04

Develop

Required API endpoints, integration logic, webhooks, authentication, and data processing are implemented.

05

Test

Requests, responses, errors, authentication, edge cases, and important workflows are tested.

06

Deploy

The integration is deployed to the appropriate environment and configured for production.

07

Monitor & Support

We can continue supporting the integration as APIs, business requirements, and connected systems evolve.
