About this gig

I will connect your website, web application, or business systems using APIs and reliable integration workflows.


I can integrate websites and applications with payment gateways, CRMs, ERPs, shipping systems, e-commerce platforms, accounting tools, notification services, and other third-party systems.


Services include:

  • REST API integration
  • Payment gateway integration
  • CRM integration
  • ERP integration
  • Webhooks
  • Data synchronization
  • Order synchronization
  • Product and inventory synchronization
  • Authentication and API security
  • Custom API endpoints
  • Third-party service integration
  • API troubleshooting
  • Legacy API integration


I can work with existing Laravel/PHP applications as well as suitable web-based platforms.


Please provide the API documentation or explain the systems you want to connect before ordering. Multi-system integrations should be discussed first so I can map the data flow and scope correctly.
