About this gig

I will integrate third-party APIs into your website, web application, software, or custom system with a reliable and scalable implementation.

Whether you need a simple REST API connection or a complex multi-endpoint integration, I can connect your system with external services and ensure data is transferred correctly and securely.


I can help with:


  • REST API integration
  • JSON & XML APIs
  • SOAP APIs
  • Third-party API integration
  • Custom API development & integration
  • Webhooks & real-time data
  • API authentication, API keys & OAuth
  • Data synchronization between systems
  • Payment, CRM, ERP, shipping and other service APIs
  • PHP, JavaScript and backend API integrations
  • API troubleshooting, debugging and error fixing


I can work with existing applications or build the required integration from scratch. I will review the API documentation, handle authentication and data mapping, implement the required endpoints, test the integration, and ensure proper error handling.


If you have API documentation or a specific integration requirement, send it to me before ordering.


I can review the requirements and recommend the best approach for your project.

    Roland is very competent and did a wonderful job updating our website. He was a pleasure to deal with and happily took on feedback and quickly made the requested changes. I highly recommend engaging Roland for similar jobs and I look forward to continuing to engage him for future web service needs.
