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.
