About this gig
Need to connect your application with another system or fix an existing API integration?
I develop and integrate APIs that allow applications, ecommerce platforms and business systems to exchange data and work together reliably.
I can help with:
- REST API development and integration
- Third-party API integration
- Existing API troubleshooting and fixes
- Authentication and API access
- Database and API connectivity
- JSON request and response handling
- Webhooks and data synchronization
- Ecommerce and business system integrations
- PHP and CodeIgniter API development
- Testing and debugging integrations
My experience includes connecting ecommerce platforms with business and logistics systems for order processing, shipment booking, tracking, reporting and other operational workflows.
I can work with an existing integration or develop new API functionality based on the documentation provided by the external service.
Please contact me before ordering for complex integrations, multiple systems or APIs with extensive business logic so I can review the documentation and recommend the right scope.
Send me the API documentation and a brief description of what the two systems need to exchange.
