About this gig
Is your WordPress REST API failing, webhook not triggering, or authentication/CORS blocking your integration? I can troubleshoot the issue, identify the root cause, and get your API connection working correctly.
I help fix WordPress REST API integration problems involving:
- REST API errors: 400, 401, 403, 404 & 500
- API authentication, tokens & API keys
- Webhook setup, failures & payload issues
- CORS and cross-origin errors
- Third-party API integrations
- JSON request/response & data mapping
- API endpoints, headers & parameters
- Data synchronization and connection issues
Instead of only identifying the error, I investigate the API request, response, authentication, webhook and data flow, fix the underlying problem, and test the integration.
Please provide your API documentation, error message/logs, and relevant access or code before I begin.
Have a complex API integration? Message me before ordering so I can review the requirements.
