About this gig
Is your API failing, your webhook not triggering, or your backend throwing errors?
I help troubleshoot and fix API and backend problems that are stopping your website, app, automation, or integration from working properly.
I investigate the root cause instead of simply patching the visible error, then apply the appropriate fix and test the affected functionality.
Problems I can help solve:
- REST API requests failing or returning unexpected responses
- Webhook failures or events not being received
- Authentication and authorization errors
- JSON, endpoint, and integration errors
- Stripe, Twilio, CRM, and third-party API issues
- Broken Zapier or Make.com automations
- Node.js and Express.js backend errors
- Database connection and backend integration problems
- Payment gateway integration issues
- API timeout and unexpected server errors
What you get:
- Investigation of the reported problem
- Identification of the likely root cause
- Implementation of the required fix
- Testing to verify the solution
- Clear explanation of what was causing the issue
API, webhook, integration, or backend not working? Send me the issue and Ill find the cause and fix it.
