API Development, Integration & Troubleshooting


Is your API not working, returning errors, failing to connect, or not syncing data correctly?

I will develop, integrate, troubleshoot, and fix APIs for your website, web app, mobile app, SaaS, WordPress, WooCommerce, Shopify, or custom application.


I can work with REST API, JSON, XML, SOAP API, third-party API integrations, webhooks, authentication, API requests, data synchronization, and custom API development.


I can help with:

  • API integration and third-party API connection
  • REST API development and integration
  • API errors and failed requests
  • 400, 401, 403, 404, 429 and 500 errors
  • Webhook setup, debugging and troubleshooting
  • OAuth, API keys, tokens and authentication
  • JSON, XML and SOAP API integration
  • Stripe, PayPal and payment APIs
  • Shopify and WooCommerce APIs
  • WordPress REST API and custom integrations
  • API synchronization and data exchange


My process is simple: I review the issue, identify the root cause, implement the fix or integration, and test the result.


Please contact me first so I can confirm the requirements and provide the right package.
