I will fix shopify store errors, API and webhook integration issues


About this gig
Is something broken in your Shopify store or integration? I find the root cause, fix it, and send you a short written report.
What I can fix:
- Shopify Admin API errors (REST and GraphQL: 401, 403, 404, 429)
- Webhooks that do not fire, fail or return errors
- App and third-party integration issues (OAuth, tokens, permissions)
- Orders, inventory or customer data not syncing
- Checkout, email notification and other store errors
How it works:
1. You send the error message and screenshots.
2. I investigate logs, API responses and settings.
3. I fix it, test it and explain what was wrong.
Why me: I have 4.5 years of experience troubleshooting e-commerce application incidents with logs and APIs. I also built my own Shopify app, so I know the platform from the developer side.
Please note: this Gig is for fixing errors, not for theme design or full store setup. One order covers one issue. Use the extra for additional issues.

FAQ
Do you need access to my store?
Often I only need the error message and screenshots. If I need to look inside your store, I will ask for Shopify collaborator access. It can be removed any time. Please never share your password.
What kind of issues do you fix?
API errors (401, 403, 404, 429), webhooks that fail or do not fire, app and integration problems, data sync issues and store errors. I do not do theme design or full store setup.
What happens if you cannot find the cause?
I will tell you honestly what I found and what I could not confirm. If I cannot fix the issue, we can cancel the order so you are not charged for work that did not solve it.
How fast can you deliver?
Standard delivery is 3 days. If your store is losing orders or sales, choose the 1-day fast delivery extra and message me first so I can confirm I can start right away.
